The structure of PCBs makes it simpler for electronics manufacturing companies to integrate more designs into their products without bordering about the more wires and components sticking out.

One of the causes for concern when designing Printed Circuit Boards (PCBs) is the temperature. Indeed, a PCB that has a higher temperature can be a challenge. And if you have come across one of that, you will know that the physical attributes of the circuit board can be negatively affected by the temperature.

In this article, we will teach you all you need to know about high-temperature PCB. Whether you are looking at how to calculate the temperature or how to reduce the same, we have everything covered here.

You can be confident that this is the most extensive high-temperature PCB article you will read and all the questions you may have are answered here.

What Is High-Temperature PCB?

high temperature material

First things first – let us consider the meaning of high temperature Printed Circuit Board (PCB). Of course, as the name suggests, you may be forced to believe that it has to do with circuit boards that have more temperature than expected.

Of course, that perspective isn’t entirely wrong, but there is more to high-temperature PCB that you need to know about.

To put it simply, a high-temperature PCB is the type of circuit board that has materials that can conveniently withstand up to 170 degrees Celsius of heat transfer.

Understandably, you may not have an idea of what this is and how it works. That is why we put in the work to provide in-depth information on the role of heat transfer in PCBs, especially as it relates to high-temperature PCBs.

The Epoxy Glass Perspective

For you to understand the need for high-temperature PCBs, we will like you to understand where it starts from, and that is from an epoxy glass.

The idea is that an epoxy glass is required at the onset because it contains polymers, which are needed for creating the base of circuit boards. That is of course after the polymers must have been melted down.

With that in mind, the next step will be to record the Tg Levels, which is a glass transition temperature that is derived when the polymers are melting.

It is on that note that the Tg Levels will be distributed for manufacturing different circuit boards depending on the needed heat transfer.

Market Demand for High-Temperature PCBs

You may be a newbie to the use of circuit boards that have a high temperature. It may also be that you have been using that type of circuit board for some time, but you are not sure if you are making the right choice.

Therefore, you need to understand the real reasons why many consumers are always looking for high-temperature PCB manufacturers instead of traditional PCB designers.

Below are some of the reasons/factors that are driving market demand for high-temperature PCBs:

1. Cost-Effective

The first factor that motivates consumers and electronics companies to use PCBs of high temperature is because of the costs.

Indeed, it has become clear that the costs of manufacturing regular circuit boards are almost in the same price range as the costs of manufacturing high-temperature PCBs. Therefore, it makes sense to choose the latter because it has more potentials than the traditional PCBs do.

2. Turnaround Time

The other factor is that it takes lesser time to design circuit boards of high temperatures. It is possible because there may be little or no need to modify the board, as you would have if you were to design the traditional PCBs.

3. Efficiency

The last but not the least is that the effectiveness and efficiency of the circuit board wouldn’t be in doubt.

For instance, a high-temperature PCB has higher Tg Levels, and that is the reason why the circuit board provides advanced features that aren’t readily obtainable in traditional PCBs.

How to Design High-Temperature PCB

By now, we are sure you are getting the drifts as to why circuit boards that have a higher temperature tend to stand a higher chance of adoption than the traditional PCBs.

In lieu of that, you are now looking for ways to design one of those circuit boards. We must point out here that the designing process isn’t always easy, because some proactive steps need to be taken to preserve the board.

Because of the technicalities involved, it is advised that you hire the services of an experienced high-temperature PCB manufacturer to help you design the board.

Haven said that; let us now consider some of the things that must be in place before a high-temperature circuit board can be designed.

1. Pick the Appropriate Components

Worthy of mention is that the design of a high temperature Printed Circuit Board (PCB) with the design of the traditional PCB isn’t the same.

Particularly, the difference stems from the materials used in putting the boards together. Therefore, pay special attention as we share the relevant high-temperature PCB materials that you can readily use for designing the circuit board.

Core Materials

The first thing we must consider is the core materials or components that will aid in the design of high-temperature PCBs.

The two most commonly used materials are:

  • Polyimide and
  • FR-4

Note: We must stress it here that the aforementioned 2 materials are basically used for designing the base of the circuit board. That implies that if there was to be a need for high-temperature uses, those materials may not withstand the heat.

In light of that, we have no other option than to go shopping for relevant materials that will optimize the base materials for long-lasting effects, especially in the face of higher temperatures.

Solder Paste

Solder paste proves to be a veritable means of improving the temperature of circuit boards. In that case, we are looking at the possibility of sticking all the components together so they don’t fall off from the circuit board.

Heat Management Details

You must also consider information pertaining to the details of heat on the circuit board. For that to happen, you must look at the required heat management specifications on the board so you don’t make mistakes when adjusting the design to accommodate high temperatures.

Component Placement

As much as a circuit board with more temperature is ideal, it can also be problematic. That is why a professional high-temperature PCB manufacturer must always consider the best ways of placing the components on the circuit board.

There is no rocket science attached to this because it can be readily completed if you have an idea of what to look at how to place the same.

The general rule is that those components that tend to aggravate/create more heat on the circuit board must be separated or placed in farther distances. The reason for doing that is that more spaces will be created on the circuit board for more component placement, just as it helps to cut down on excess heat transfer.

Here are some of the components that are likely to create excess heat, and which must be spaced as fast as possible to prevent damage on the board:

  • Regulators
  • High power resistors

 

Causes of High Temperature on PCBs

Tg170 PCB

While a high-temperature PCB can be the real deal, it seems to have a fair share of bad attributes too.

So, in this section, we are going to consider some of the factors that facilitate excess high temperature on Printed Circuit Boards (PCBs).

Note that the consideration here is to highlight the reasons why it is difficult for high-temperature circuit boards to function effectively because their functionalities have been hampered by irregular heat distribution on the circuit board.

Below are some of the major causes of excessively high temperatures on Printed Circuit Boards (PCBs):

2. Poor PCB Design

Obviously, when the right designs aren’t in place, it becomes hard for the circuit board to function effectively. That informs the reason why a poor design is the first factor that reduces the efficiency of high-temperature PCB.

So, how can a poor design be the reason why the temperature of your circuit board keeps rising?

Inadequacy of the Copper Area

The first factor is that the inadequacy of the copper area or the trace width can be the first sign that the temperature of a circuit board will rise.

Most times, it can also trigger inconsistent temperature increases that can impede the viability of the circuit board.

Impeded Heat Dissipation

As much as heat is needed on a high-temperature PCB, it doesn’t have to be excess too!

For that reason, you have to consider some of the poor layout and design mechanics that could impede or reduce the speed of dissipating heat from the circuit board.

3. Non-Strategic Component Placement

The second factor that can cause the excessively high temperature on circuit boards is incorrect component placement. The idea is that if the manufacturer isn’t strategic about placing the high-temperature PCB materials in different locations, it can impede the strength of the board.

In light of that, proactive steps must be taken to ensure that some of the components that need more airflow are strategically placed where their heat will be conveniently dissipated.

Furthermore, if such high-powered components aren’t placed close to where excess heat from them can be forced out, it wouldn’t be long before such heat compounds to increase the temperature of the circuit board over time. As such, the circuit board wouldn’t take much time before it damages.

Incorrect Spacing

In addition to transferring away heat in good time, it is also ideal to space the components.

The rule of thumb is to space or place those components that are sensitive to be far from other components on the board that tend to emit excess heat.

4. Wrong Material Selection

You may make the mistake of selecting any high-temperature material you think is best, but which isn’t the best anyway.

Selecting a wrong PCB dielectric material implies that such material might not conveniently withstand thermal conditions when they become excessive.

5. Component Misplacement

You can also make a mistake when selecting a component for your high-temperature PCB.

Have in mind that you have to liaise with a professional high-temperature PCB manufacturer to select the best components that will be used for designing the circuit board. The best way to go about that is by studying the datasheet.

To give you a heads-up, some of the factors you must consider when selecting components for your high temperature Printed Circuit Board (PCB) include but are not limited to:

  • Temperature limits
  • Cooling techniques
  • Method of dissipating heat/power and
  • Thermal resistance

 

How to Measure the Temperature of High-Temperature PCB

Do you want to measure the temperature of your Printed Circuit Board (PCB)? You need to do that so you can easily identify the possible causes of the increased temperature as a way of reducing the temperature too.

Here are some of the significant PCB temperature reduction strategies you can use:

  • Keep the heat source and temperature sensor at a reasonable distance
  • Connect all the GND pins of the temperature sensors to the ground plane where heat emanates from.
  • Ensure that you use a common ground plane between the source of heat and the temperature sensor.

 

How to Reduce PCB Temperature

What do you do when you find out that the temperature of your circuit board is continually increasing?

We bet you want to find ways of reducing the heat so it doesn’t negatively affect the performance of the board.

If that’s what you want to do, here are some of the strategic ways of cutting down excessive heat transfer on your high-temperature circuit board:

  • Channel the built-in cooling fans to allow cool air into the circuit board while pushing out hot air.
  • Implement Conduction as a way of initiating the transfer of heat by initiating direct contact between the heat sink and the heat source.
  • Invest in thicker and wider plates to resist excessive heat on the high-temperature PCB.

 

Conclusion

When you have put all those factors into consideration, it will do you a world of good to use the services of a qualified and professional high-temperature PCB manufacturer to design an ideal circuit board that will be highly effective.

Impedance control is an important consideration when looking for components to use in a Printed Circuit Board (PCB). That is also why consumers and electronic companies are always exploring options to get the best impedance matching in PCB.

In this article, we will walk you through the basic concept of impedance control as it pertains to circuit board design. You will also learn about the best ways of calculating impedance control in a circuit board, as well as how to control it and the best manufacturers/factories you can rely on.

pcb trace impedance

What Is Impedance Control in PCB?

The first thing we want to consider is the meaning of impedance control. An understanding of the concept will make it simpler for you to realize the importance of using it as a control measure in your circuit board.

Impedance control refers to the reactance and resistance that a circuit board is expected to attain so that the design will be perfected.

Also, impedance control involves the propagation of signals in a Printed Circuit Board (PCB) without distortions. The control measure must be applied because it helps to provide a repeatable high-frequency performance of the circuit board it is used on.

How to Determine Impedance Control of a Printed Circuit Board

Do you want to determine or find out if your circuit board has the right impedance control? It is simple if you know what to look for.

The first thing we want you to understand is that the impedance of Printed Circuit Boards (PCBs) is determined by the materials used in designing the circuit board. It is also determined by the physical dimensions of the circuit board. Above all, the impedance control of a Printed Circuit Board (PCB) is measured in Ohms (Ω).

That said, let us now walk you through the other important factors that contribute to the evaluation/determining of the impedance control of a circuit board.

1. Trace Impedance

The first thing you must have in mind is that the impedance of the trace is one of the most important elements of the circuit board.

For that reason, you should be aiming for trace impedance control of 25 and 125 Ohms.

2. Targeted Impedance Value

The second way of determining the impedance of a circuit board is to figure out and aim to meet the targeted impedance value.

What this means is that the PCB manufacturer/designer must ensure that the stack-up and choice of trace used in the circuit board are designed to meet the targeted impedance value. It also makes sense that a certain tolerance is maintained, especially when it involves high-frequency signals.

3. Solder Resistance

The presence of solder resistance on the circuit board can also be another factor that influences the control of impedance on the Printed Circuit Board (PCB).

Aside from those, there are many other ways of determining the impedance control of a circuit board. They include:

  • The width and thickness of copper traces
  • The distance of the impedance control from the reference copper plane.
  • The method of passing the signal through vias
  • Prepreg and core material dielectric constant
  • Prepreg material thickness of core thickness on each side of the trace

 

Service Levels for Impedance Control

You now know some of the basics of impedance control PCB. Now, we will look at how the same control can be used for facilitating control and propagation of signals in a circuit board.

Ideally, there are 3 service levels/methods of facilitating impedance matching in PCB. They have been explained below so you will have a better idea of how they work in a circuit board.

1. Impedance Control

this is the ideal concentration and basic of impedance control in the Printed Circuit Board (PCB).

If this is what you want, it implies that the PCB manufacturer/designer will have to continually make efforts to design the circuit board until the required/expected impedance control is attained.

2. No Impedance Control

For some reason, you want to use the second level of service, which entails the removal of impedance control.

In such an instance, additional efforts will not be made to hit the desired/expected impedance level because the tolerance of the impedance is already loose/low.

Since additional design elements wouldn’t be required, it means that the PCB manufacturer will expedite action in the manufacturing of your Printed Circuit Board (PCB).

3. Impedance Watching

Last but not least is Impedance Watching. It is considered one of the most tactical because of the adjustments that need to be made.

Ideally, the designing of a circuit board using Impedance Watching entails that the PCB designer/manufacturer will have to outline the traces of the impedance control on the circuit board. After that is done, the next step is for the provider to accordingly adjust the trace width and the dielectric height. That way, there will be uniformity in the design.

But, that is not all there is to it. After the necessary adjustments, the PCB manufacturer will need to approve of the specifications you made for the circuit board. It is only after the approval that the quality impedance control factory will start working on the design.

How to Control Impedance of PCB

Do you want to know the best ways to control impedance in a Printed Circuit Board (PCB)? It is not rocket science because it is something you can do with the help of your PCB manufacturer.

Here are some of the excellent strategies you can always use to control the level of impedance in your circuit board:

1. Measurements

The first step is to have an accurate measurement of the impedance level that is to be used in the circuit board. The reason is that a measured impedance level has its way of regulating the overall stability of the circuit board.

For example, if you were working on a TV cable or satellite, the first thing you want to do is to set the coaxial cable of the TV to act as a conductor while the antenna will work as the source. When that happens, it will be easier to measure and control the electrical impedance of the cable by evaluating the characteristics of other important elements, including:

  • Conductors and
  • Insulators

 

2. Matching impedance

Truth be told – nothing can be achieved if there was no way to ensure that the impedance of the circuit board matches. That brings us to the second approach to controlling the impedance of a circuit board.

The idea here is that the PCB manufacturer/designer needs to ensure that the signal on the circuit board smoothly moves from the source of a message to the load.

Also, we must emphasize that the reason for looking into this is that if the input impedance and output impedance match, then the same should be extended to ensuring that the load impedance and reference track must also match.

3. Testing

finally, the circuit board in question must be subjected to rigorous tests because that is one of the excellent ways of finding out potential downsides to the board’s design.

 

Impedance Control Verification

Now, we must consider another important aspect of impedance control in Printed Circuit Boards (PCBs). We are talking about how to verify or confirm the validation of the impedance control.

Usually, the importance of impedance control verification or measurement is meant to uncover some of the loopholes that might limit the viability of the circuit board.

There are many methods of measuring impedance control in a circuit board, but we will discuss some of the popularized ones so you will have an idea about how they work.

Use High-Quality Cables and Probes

The first method of verifying or measuring impedance control of a circuit board is to use high-quality cables and probes. The idea is that if the probes or cables are used, they will simplify the process of evaluating the circuit board.

Besides, you might want to resort to using gated cursors because they play an important role in obtaining the mean value of the board.

Third, you might be interested to use the third option of using calibration quality adapters, especially when there is an urgent need to use RF adapters.

Test Coupons

The second method is to use test coupons. There is no doubt that test coupons play an important role in the evaluation and measurement of the impedance control of a circuit board.

The reason for that is not unconnected to the fact that test coupons are typically fabricated at the edges of the circuit board.

Because of that, the coupons have become a veritable method of facilitating inspection of internal structures, layer alignment, and electrical connectivity of the circuit board.

Time-Domain Reflectometer (TDR) Can Help

The third option you want to explore is the Time-Domain Reflectometer (TDR). It is primarily used for measuring the impedance level of a Printed Circuit Board (PCB) by sending signals along a line and measuring the part of a message in the signal to confirm if the impedance matched or not.

Mistakes to Avoid When Designing a Circuit Board for Impedance Control

pcb impedance calculator

We would like to point out that some mistakes tend to be made if the PCB manufacturer is not careful. These mistakes can be avoided if the manufacturer/designer is certain of the potential causes so it will be easier to address them.

For this article and not to make things complicated for you; we have sub-divided these mistakes into different parts. That way, you will have a general overview of each of the potential places that the mistakes can be reflected in the design of the circuit board.

Mistakes to Avoid During Stack-Up

The first mistake that PCB manufacturers make is usually when the stack-up of the circuit board is being designed.

We have taken the time to evaluate some of the potential mistakes that can be avoided during the stack-up of the circuit board, especially as it pertains to impedance control PCB.

Impedance Space/Trace

The first mistake is made in the spacing of the impedance traces. In this case, the PCB manufacturer must be careful because not spacing the impedance trace well enough can reduce the movement of signals on the circuit board.

To that end, the spacing between the two traces of the circuit board must not be more than twice the width of the traces.

Also, the PCB manufacturer must make conscious efforts to ensure that the width of the trace is not two times more than the dielectric thickness between the nearest reference layer and the target signal layer.

Prepregs

The major mistake that must be 3 different types of prepregs must not be used in a stack-up of the circuit board.

Mistakes To Avoid During Routing

Some mistakes must be avoided during the routing of the Printed Circuit Board (PCB).

Length Mismatch

The ideal length that must be used to prevent mismatching is to maintain a length match of +/-5 mils of the different pairs.

Traces Crossing Split Planes

Traces can be prevented from crossing the split planes by ensuring that they are not routed across a split plane.

How Is PCB Impedance Calculated?

There are different methods used for the calculation of PCB impedance. Some of them have been explained below:

Use an Online Calculator

The quickest way to calculate the impedance of a circuit board is to use an online calculator provided by your PCB manufacturer. You can easily locate that on the manufacturer’s website.

Smith Chart

The second option you have is to use the Smith Chart. The work of the chart is to graphically highlight and determine the coefficient relationship between the load and source impedances on the circuit board.

Computer Simulation

Using computer simulation is another excellent way of figuring out the impedance of a circuit board. It works by enabling automatic modification of the relevant parameters that will be used for selecting the best design to use for the circuit board.

However, using computer simulation as a PCB impedance calculator has a notable downside, which is the higher cost of using the software.

Conclusion

Impedance control helps you to have an idea of the quality of your PCB design while making it easier for you to find out potential mistakes and errors.

You have many reasons to use the FR5 PCB materials in your next Printed Circuit Board (PCB) design. Indeed, there are many consumer needs as they relate to PCBs, and having one of the best materials is a good way to start.

We are pleased with what the FR5 PCB has to offer. That is why we have come up with this comprehensive guide to give you a heads-up on everything you need to know about this type of PCB material.

What Is FR5 PCB?

The FR5 substrate is made up of woven glass reinforced material and an epoxy resin binder. It is one of the most used materials for the design and manufacturing of circuit boards.

In terms of the specifications, there are many features that you will like about the FR5 PCB. The first is the maximum operating temperature of 140 degrees, which ensures that the circuit board doesn’t overheat or goes above the recommended temperature. The second attribute is the thermosetting fiberglass composite that is there to further enhance the resistance of the circuit board to a flame.

Worthy of mention is that the FR5 PCB isn’t the only type of PCB material out there. There are many of those, and these include the FR1, the FR2, and the FR4 PCB materials. That is not leaving out the FR4 PCB material, which is a fierce competitor to the FR5 PCB material.

The Competition between the FR4 and the FR5 PCB Materials

It is not out of place for a variant of the Printed Circuit Boards (PCBs) to provide better features than what the others would. That has been the basis of the competition between the FR5 PCB and the FR4 PCB materials.

Interestingly, the similarity between the two is impressive. They both have multiple use cases, including high-temperature applications.

However, the primary difference between the two lies in the heat resistance and the number of layers that each of the materials can be used.

Features of the FR5 PCB Material

For maximum comprehension of what you stand to benefit from using the FR5 PCB, we will like to highlight some of the features.

1. Moisture Absorption

There is no doubt that the removal of moisture, especially when it becomes excessive is one of the important elements to be considered when selecting a PCB material.

In the case of the FR5 PCB, the moisture absorption is low. To that end, it will make a good material to be used for your next circuit board.

2. Resistance

If a circuit board can resist many things, it implies that the chances of developing faults will be lower.

That inspires why the design of the FR5 PCB is impressive with the high chemical resistance. That is not leaving out the fact that it has a low dielectric loss.

3. Mechanical Properties

While checking the components of a PCB material, one of the important things to look at is the properties that are tenable in the mechanics of the circuit board.

Interestingly, the FR5 PCB has mechanical properties that are not only impressive but also enhance the functionalities of the circuit board where it is used.

4. Excellent Performance

There are many ways to evaluate the performance of a circuit board. That includes but is not limited to the mechanical properties and the entire composition of the board.

Therefore, investing in the FR5 PCB is the right thing to do considering the excellent performance. One of the ideal ways of confirming the performance of the FR5 PCB is by checking the performance during the lead-free soldering process.

Use Cases

Are you looking to see where the FR5 PCB will be deployed? Well, there are many use cases and applications where circuit boards designed with the FR5 PCB material can be deployed.

We will explain just a few so you will understand that the use cases and applications are not only many but are channeled in the right direction.

High-Temperature Applications

If there is anything that endears consumers to the FR5 PCB material, it is the excellence as far as high-temperature applications are concerned.

Already, the FR5 PCB material has many components that are in one way or the other, designed to reduce the heating on the circuit board.

PCB Testing

As awkward as this may sound, one of the major use cases and applications of the FR5 PCB is when it is time to test the circuit boards.

Sometimes, the PCB manufacturer may have made some mistakes in the process of designing and manufacturing the circuit board. In some other cases, the consumers may not be satisfied with the outcome of the design.

No matter the outcome of the design, the fact is that something could be done to forestall the negative outcomes. That is the essence of the PCB testing undertone to the FR5 PCB. With this, you can check and evaluate your circuit board before it is released

Serves as Insulation Structural Parts

The insulation properties in the FR5 PCB are many. And considering that the insulation of a circuit board is an important element for protecting the board from overheating, the insulation properties of the FR5 PCB will come in handy.

According to the PCB industry analytics, the components of the FR5 PCB can be used as insulation structural parts.

Also, the primary use cases or applications of these parts are in the electrical equipment and motor.

Automotive Industry

It is time you know that most of the Printed Circuit Boards (PCBs) used in automobiles are made from the FR5 PCB material.

One of the major reasons why PCB manufacturers, as well as the consumers, are pleased with the material is because of the improvements in the Tg, which is the Glass Transition Temperature.

Therefore, the higher glass transition temperature of the FR5 PCB pegged at 160 degrees, as well as the maximum operating temperature of 140 degrees goes the extra mile to improve the sturdiness of the components of automobiles where it will be used.

Aside from that, there are some other use cases of the FR5 PCB. That includes the use in the designing and manufacturing of circuit board holders, solid frames, antenna isolators, and test boards.

Why the FR5 PCB Is Better Than the FR4 PCB

fr5 pcb manufacturer

You may be wondering why the FR4 PCB is competing with the FR5 PCB. The fact is that both have something unique to offer, as far as the designing of Printed Circuit Boards (PCBs) is concerned.

Aside from that, there are some advantages and reasons why the FR5 PCB is steadily topping the charts over the FR4 PCB.

Here are some of the better advantages that the FR5 PCB has, which help to set it apart from its fierce competitor – the FR4 PCB.

1. Smaller Z-CTE

The first advantage that the FR5 PCB has over the FR4 PCB material is the size of the Z-CTE.

Because of the smaller size, the FR5 PCB is undoubted, ideal for multiple use cases. That is why PCB manufacturers don’t find it difficult to use the same for high multilayer circuit board designs.

2. Higher Tg

The higher the Glass Transition Temperature (Tg), the more the use cases and applications of the PCB material.

Without any iota of doubt, the other reason why the FR5 PCB is better than the FR4 PCB is because of the higher Tg. It is because of the higher and improved Glass Transition Temperature (Tg) that the FR5 PCB is the best PCB material for the job.

3. Good Insulation Properties

The point is that if a circuit board doesn’t have good insulation, it tends to overheat.

Just as the Tg is improved, FR5 PCB also made plans to insulate the circuit board so that it wouldn’t be negatively affected by the outcome of overheating.

Besides, the good insulation properties of the FR5 PCB makes the difference, as it helps in keeping overheating at bay.

4. Better Heat Resistance

There is no gainsaying that the FR4 PCB has a good heat resistance that prevents the circuit board from overheating.

Yet, there are many other important factors to consider. That is where the FR5 PCB comes in with better heat resistance.

When checked, the heat resistance of the FR5 PCB is about twice of what it derivable on the FR4 PCB.

5. Moisture Resistance

It makes sense to keep moisture or water out of the circuit board. Even when you are watching, there is a likelihood that moisture may still find its way into the Printed Circuit Board (PCB).

In light of that, the moisture resistance of the FR5 PCB is a great consideration. Ideally, what is done here is to absorb moisture so that the filtration into the circuit board will be lower.

6. Electrical Strength

The other important consideration of the FR5 PCB is electrical strength. Because every component is important and the electrical is highly valued, it makes sense that the strength of the same should be solidified.

The input of the FR5 PCB in this regard may not be fully explained. However, the takeaway is that the use of the FR5 PCB material in a circuit board goes the extra mile to provide good electrical properties to the circuit board.

FR5 PCB Designs

There is no end to what can be made out of the FR5 PCB. The PCB manufacturer is expected to have an eye for details, as well as understand the procedures so that it can have a swell time when designing the FR5 PCB.

Of course, there are different PCB designs that can be made out of the FR5 PCB. Below are some of them:

Double-Sided PCB

If you are looking at designing a Printed Circuit Board (PCB) that has two sides, it is pertinent that you consider the Double-Sided PCB designed under the auspices of the FR5 PCB material.

Rigid

The rigid PCB can be also designed with the FR5 PCB as the base material. The expertise of the manufacturer and the availability of the needed materials will determine the success of the job.

Multilayer

On the other hand, there is an opportunity for you if what you are considering is a PCB that has more than two sides.

In that case, the multilayer property of the FR5 PCB is what you will need to design a circuit board that has multiple layers.

How to Select the Best FR5 PCB Manufacturer

It is one thing to understand and cherish all that the FR5 PCB has to offer. It is another thing to make it reality by selecting the best PCB manufacturer for the job.

If you are at a crossroads or you don’t know what to have in mind when considering a manufacturer, we are here to help you.

Here are some of the factors that will help you get the best PCB manufacturer that will help you hire the best FR5 PCB manufacturer:

1. Location

You want to confirm that the PCB manufacturer is close to you. The proximity of the manufacturer matters a lot because it helps you to always walk in or be in constant communication with the PCB manufacturer to ascertain the status of your design.

2. Material Sourcing

This can be the source of problems between the PCB manufacturer and the consumers if it wasn’t talked about at the onset.

So, you have to determine if the PCB manufacturer is willing to source for the materials for the circuit board.

It is important that the FR5 PCB manufacturer does the sourcing because of the expertise and the immediate access to the materials upon payment.

3. Cost

No doubt, an excellent PCB material like the FR5 PCB tends to attract more costs. Therefore, ensure that you did some market research and background checks to confirm if the quoted cost of the circuit board you want to design fits into your budget.

Final Words

Printed Circuit Board (PCB) materials are one of the important components that aid in the designing and production of printed circuit boards. You want to get the type that does not only solidify the design of the circuit board but also makes it easier for the manufacturer to design the same.

There are many types of Printed Circuit Board (PCB) materials out there. With the variety of options, you may a bit confused about the material that will perfectly fit into the design you expect on your circuit board.

We are pleased to let you know that the FR1 PCB material is one of the best. You are also lucky to be reading this guide because you will learn all you need to know about designing a Printed Circuit Board (PCB) using the FR1 PCB material.

What Is FR1 PCB?

The first thing we must do is to define or explain what the FR1 PCB material is and does. With that knowledge, you can conveniently map out the strategies that will enhance the use of the FR1 PCB material on your next circuit board.

The FR1 PCB or Flame Retardant 1 PCB is a Synthetic Resin Bonded paper that is made up of phenol-formaldehyde resin. It is commonly used for the manufacturing of Printed Circuit Boards (PCBs). Worthy of mention is that the FR1 material is also used as PCB Laminates with a glass transition temperature that ranges between 120 and 130 degrees.

Worthy of mention is that the FR1 PCB is classified into different types. The common types are Non-Hydrophobic, Standard, and Halogen Free.

FR1 PCB and FR2 PCB

FR 1 PCB Factory

More often than not, the FR1 PCB material has been compared to the FR2 PCB. Of course, the comparison isn’t out of place considering that there are some similarities and differences between the two.

Talking about the similarities, the FR1 PCB has one characteristic with the FR2 PCB, and that is the design of phenol compounds and paper. The other similarity between the two is that they are both used for manufacturing single layer PCBs.

The major difference between the FR1 PCB material and the FR2 PCB material is the glass transition temperature. While the FR2 PCB has a glass transition temperature of 105 degrees, the FR1 PCB’s can be as high as 130 degrees.

Use Cases

There are special designations where the FR1 PCB can be used. We want you to understand that so you wouldn’t bug your PCB manufacturers with requests that might not be granted.

The primary use case of the FR1 PCB material is for 1-layer PCBs, otherwise called the Single Layer PCBs. The reason for that is that FR1 PCB cannot successfully pass through holes.

However, if you are looking at designing multiple circuit boards, it makes sense that you explore other options. The FR3 PCB material is completely out of the equation because it doesn’t offer much of what is needed. Rather, the FR4 PCB material is the best because it is versatile with the designation as a multi-layer PCB. It implies that the FR4 PCB material can conveniently aid in the design of single layers and multi-layer Printed Circuit Boards (PCBs).

Designing of PCB Substrates

PCB Substrates are an important addition to any circuit board. Because of the impressive roles they play on the board, they must be considered at all times when PCBs are been manufactured.

For that reason, the other use case or application of the FR1 PCB material is in the designing of PCB Substrates. What the material does here is that it aids in the manufacturing of PCB Substrates.

For the records, PCB Substrates is a flat board where the traces and components of the circuit board are attached.

Low-Cost Applications

The other use case or application of the FR1 PCB is in the manufacturing of electronics that don’t cost much.

This is mainly because the FR1 PCB materials are affordable and the designing procedures are simplified.

Features of FR1 PCB

Are you wondering about the features and characteristics of the FR1 PCB? There are many of them, and we will like you to be aware of those.

Below are the details of the features and properties of the FR1 PCB:

Durability

The durability of the FR1 PCB isn’t in doubt because it is highly durable. So, if you have been looking for a PCB material that can thrive despite the pressure and load it carries, the FR1 PCB material is the one to go for.

Excellent Mechanical and Electrical Properties

The mechanical and electrical components are the other elements that can sway consumers to select a particular PCB over the others. That is exactly what we have here on the FR1 PCB.

The FR1 PCB has one of the most impressive properties as far as the electrical and mechanical components are concerned.

Aids in Electrical Insulation

Electrical insulation is of the utmost importance as far as the designing of Printed Circuit Boards (PCBs) is concerned. The other reason why companies and consumers are always ready to use the FR1 PCB material is because of the inputs in the insulation of the electrical components on the circuit board.

It must be mentioned that the FR1 PCB Laminates play a vital role in the provision of the required insulation anywhere and anytime it is required on the circuit board.

Superior Finish

How is the finish of the circuit board? The last-minute touches should not only be classy but should align with the overall design of the circuit board. In that case, the FR1 PCB Laminates’ input on the circuit board isn’t to be underestimated because of the smooth surface finish superior heat resistance that it provides the board.

Mechanical Processing

If there is any feature that makes the FR1 PCB to stand out, it is the great mechanical processing capabilities.

In this case, the mechanical processing capabilities of the FR1 PCB are evident in the miling and punching that help the circuit board to withstand the mechanical pressure that may come from the board.

FR1 PCB and Other PCB Materials

There is no doubt that the FR1 PCB material is one of the best when it comes to low-end consumer electronics production. Yet, that doesn’t mean that it is the only PCB material that is used.

Indeed, there are some limitations to what the FR1 PCB can do. That is why the other PCB materials have geared up to take over the stage with the amazing properties that they have.

To that end, the limitations and lapses that are tenable on FR1 PCB are some of the reasons why the likes of the FR4 PCB material are becoming popular. Undoubtedly, the FR4 PCB material has many remarkable features that have since made it the favorite of many consumers.

It is in light of it that we will highlight the reasons why the FR4 PCB material is an option to consider if you aren’t looking to use the FR1 PCB.

What Is FR4 PCB Material?

The Flame Retardant 4 (FR4) PCB material is the type that offers different options as far as PCB design and manufacturing is concerned. It is a glass fiber epoxy laminate that is mostly used after the duo of the FR1 PCB and the FR2 PCB materials have been used. Hence, it wouldn’t be out of place to posit that the FR4 PCB material may be considered when you have tried and confirmed that the FR1 PCB didn’t give the outcome you expected.

Why the FR4 PCB Is Better Than the FR1 PCB

You don’t have to look farther when it comes to the use of the FR4 PCB material. As mentioned earlier, it is an option worth considering after FR1 PCB and FR2 PCB have been considered as base materials.

1. Variety of Applications

The first reason why the FR4 PCB material is one of the best out there is because of the many use cases. You wouldn’t be limited to the use of a mono or single layer PCB as is the case when using the FR1 PCB.

The major reason why companies are pleased with the FR4 PCB is because of the adaptability to work in many situations and configurations. For example, the FR4 PCB material can be used for the designing and manufacturing of different types of Printed Circuit Boards (PCBs).

From the one-layer to the multilayer circuit boards, the FR4 PCB has all it takes to provide what is needed.

2. Material Composition

Worthy of mention is that the material used in the design and manufacture of a Printed Circuit Board (PCB) has a lot to do with the outcome. That informs the reason why many consumers are always looking forward to using the FR4 PCB.

That is not to say that the FR1 PCB material isn’t any good. Instead, it has some great potential to offer in the enhancement of the circuit board.

Nevertheless, the FR4 PCB seems to have the upper hand with the glass fiber epoxy laminate material.

Therefore, the material composition or the type of materials that a PCB has is one of the veritable factors that can influence buying decisions.

3. Wide Use

If there is any factor that can sway companies and consumers to prefer one PCB material to the other, it is a wide acceptance. This is because the general acceptance indicates that the PCB material in question has many potentials and can further improve the functionalities of the circuit board.

Since that is the case, the FR4 PCB is in a better position when compared to the FR4 PCB material. That is because it has wide acceptance, especially in China where it is massively used.

4. Cost Factor

By and large, the cost or the amount it will cost to design a PCB is another element that must be considered. Of course, both the FR1 PCB and the FR4 PCB have their quotations. It all depends on what you are looking for to get on the circuit board you want to be designed.

Despite that, it is obvious that the FR1 PCB is taking the upper hand in this case. It is popular because of the low-end production of circuit boards. So, if you are looking to save some money without having to compromise on quality, the FR1 PCB is the circuit board you can rely on.

5. Suitability for Through-Hole Technology

Through-Hole Technology is one of the elements that are in place for the designing and production of Printed Circuit Boards (PCBs). Of course, the reason for that is that it offers better precision that bolsters the designing of the circuit board.

Also, there is a need to consider the type of PCB material that will work best for the production of circuit boards. The suitability in terms of Through-Hole Technology is one reason why the FR4 PCB is ideal. The reason is not far-fetched from the fact that the FR4 PCB material enables the components to be soldered to the pads at the other side of the board.

Why You Should Consider Using the FR1 PCB Material

The differences between the FR1 PCB material and the FR4 PCB material notwithstanding, we have uncovered some of the benefits of the former.

Indeed, there are many reasons why you must consider using the FR1 PCB material for the next circuit board you want to design.

Below are some of the reasons why you should do that:

Simplified Design

When using the FR1 PCB material, you already have in mind what you expect. Because this type of PCB material is commonly used when manufacturing single-layer circuit boards, we don’t doubt that you will use for your single-sided PCBs.

That way, you wouldn’t have to bother about the design not coming out as expected because of the mistakes that may be made if the multilayer variant was to be used.

Pricing

The price or the cost of manufacturing the FR1 PCB material is also affordable. That is partly because of the mono design and mainly because of the simplified design and manufacturing processes.

Final Words

There is no doubt that the FR1 PCB material is one of the best materials that can be used to design and manufacture the type of single layer Printed Circuit Board (PCB) you want.

The differences between it and the FR4 PCB material notwithstanding, you are sure that the FR1 PCB material will offer you the anticipated design on your one-layer circuit board.

When you are ready to design one, look for the best PCB manufacturers to handle the design.

Are you looking for a company or a manufacturer that will help you manufacture different types of products, including electronics?

You shouldn’t look farther because an electronics contract manufacturer is a one-stop designer you can rely on.

This article aims to give you a headstart on what it means to hire the services of an electronics contract manufacturer for your next product design and manufacture. You will also find out the factors and the considerations you must have in mind so you will get the best manufacturer for the job.

What Does an Electronics Contract Manufacturer Do?

Electronics Contract Manufacturer

In continuation of our commitment to teaching you all you need to know, we want to explain what the electronics contract manufacturer does. When you understand this, it will be easier for you to understand all there is to using the manufacturer the next time you have a product to be designed and manufactured.

An electronics contract manufacturer is a company or a manufacturer that specializes in using the designs you submitted to design and manufacture the product (usually electronics) that you want.

So, the electronics contract manufacturer is more of an on-demand electronics manufacturer that is ready to take your designs and make the most out of the same so the desired product will come out as expected.

Aside from making the products on your behalf using the designs you submitted, the electronics contract manufacturer can also offer different services. If you are considering that, then you should look for the manufacturer that focuses on the specialty or the area you are considering,

How to Select the Best Electronics Contract Manufacturer

Of course, we are sure you are at a crossroads on what you should be looking for when you decide to use the services of an electronics contract manufacturer.

To that end, the guide we have below is all you will need to stop searching and go straight to find the ideal electronics contract manufacturer that will handle your next electronic device production.

1. Location

There are many reasons why the location of the electronics contract manufacturer you want to use should be a top priority. If you don’t have this in mind and work with it, you may just end up spending more money than you budgeted.

In case you are wondering why the location of the electronics contract manufacturer should be a priority, the few explanations below will give you the insights you need.

First, you need to find an electronics contract manufacturer that has a location or its factory close to you so you can always go for inspection. The chances are that if you are looking at only outsourcing the design and waiting for the production, it may not always happen as you expected. That is because the manufacturer may have lots of work at hand, and may not work on yours except a little pressure is exerted.

The other reason why you should prioritize the location of the electronics contract manufacturer is to establish trust and confidence. This is usually the case if you are looking to have a long-term collaboration with the manufacturer. When you visit, you will mention your expectations and expect the electronics contract manufacturer’s response to seeing if the latter can deliver what you want.

2. Health and Safety Codes Compliance

If there is anything that must not be ignored when looking for an electronics contract manufacturer, it is the compliance with the health and safety codes.

The idea behind this is that not all the electronics contract manufacturers out there take care to comply with the laid-down health and safety codes and guidelines.

Of course, if you are opportune to visit the factory, you might just have firsthand insight into the operations of the electronics contract manufacturer. From what you see, you can conclude if the manufacturer is indeed complying with the health requirements.

Also, you may want to take it a bit further by checking how the electronics contract manufacturer uses the best practices in terms of treating the workforce, as well as caring for the machinery used for the productions.

3. Turnaround Time

You must consider the time or the duration it will take the electronics contract manufacturer to produce the electronic device or appliance using the design you submitted or uploaded via the website.

Sometimes, it may take a long while before the design will be finally produced. It depends on many factors, such as the volume of productions the manufacturer already has at hand, and the volume of the design you want to be produced.

A good way to determine the potential turnaround time of the electronics contract manufacturer is when you are requesting a quote. Ideally, you know that the manufacturer is likely to deliver the project in a few weeks if the quote gets to you after a few days.

However, do not fully rely on that because the fast delivery of the quote may not explicitly imply that the manufacturer can deliver the finished product on time.

Instead, what you want to do is to ask the electronics contract manufacturer to give you the timeframe it will take for the design you uploaded/submitted to be completed and delivered to you.

4. Engineering Experience

The expertise or the experience of the electronics contract manufacturer is of the utmost importance anytime you are looking for the one to handle your next design.

The idea here is that a contract manufacturer that has been in the business for long tends to have some leverage to make your product better from what could have been tenable if it were handled by a novice.

There are some considerations that you should have in mind at all times if you are hiring an electronics contract manufacturer based on the engineering experience.

The first consideration is the mastery of the Design for Manufacturing (DFM). The concept behind DFM involves the series of steps and approaches that must be adhered to when building products out of the designs.

The second consideration here has to do with the reviews of the board’s layout. The reason why the board review must be in place at all times is because is the perfect time to find out the potentialities of errors resulting from the design and the production.

Also, when reviewing the board, the electronics contract manufacturer will brainstorm and find out other simplified ways that the product can be designed.

That is not leaving out the fact that reviewing the board affords the designer the opportunity of identifying the components and parts of the electronic device that may require special handling or advanced designs.

5. Consider the Threshold

You may just be paying more for less when you don’t have an idea of the electronics contract manufacturer threshold. The threshold here simply means the quantity that the designer is ready to handle.

Ideally, we are looking at low, medium, and high. Of course, your major concern is to see how that correlates to what you expect. Does the electronics contract manufacturer’s threshold correspond with what you want to be produced? If it doesn’t, is there any way that you can request for modifications?

To give you some instances, the threshold in view is often determined by the electronics contract manufacturer and set for a particular audience. For example, the manufacturer may decide to keep the threshold at a higher volume. In such an instance, the target audience or market tends to be the larger corporations and companies that are looking to produce multiple electronic products every month.

6. Availability of Trial Run

What happens when you finally find an electronics contract manufacturer that can handle the designs you have and at the quantity you expected?

Perhaps, you are considering handing over the entire design at once. Well, you may want to take some precautions to be sure you are on the same page as the electronics contract manufacturer is.

The rule of thumb is to ask the designer if it can offer you a trial run. That will allow you to produce only a small quantity of the design. And if it comes out as you wanted, you will want to commit the remaining designs to the manufacturer to produce that too.

7. Hire a Third Eye

You should not rule out the option of hiring someone else to help you check the quality of service that your preferred electronics contract manufacturer has to offer.

The reason is that you are not fully experienced in the contract manufacturing industry. So, you may not know what works and what doesn’t.

However, when you hire a qualified engineer to vet or check up on the electronics contract manufacturer, you will be in a better position to determine if the manufacturer is the best for the job.

8. Product Testing

You shouldn’t take the electronics contract manufacturer’s words alone. Sometimes, you have to check to see that the quality of the electronic product is the same as what you had in mind.

Therefore, it is pertinent that you ask the electronics contract manufacturer to allow you to test the product in its factory.

Among the many benefits of testing the product are that it helps to reveal the flaws and the mistakes the designer may have made, as well as the quality of the product. That is not leaving out that product testing is one of the steps to quality assurance, as it helps the electronics contract manufacturer to confirm that the products meet the expectations of the consumers.

9. Post-Production Services

It wouldn’t be a bad idea to hire an electronics contract manufacturer that offers you additional services even after the products have been manufactured. You will be lucky to get such a manufacturer because they are rare to find.

Ideally, your contract with the contract manufacturer ends after you must have confirmed that the products are as you expected and after you must have settled the bills for the same too.

However, the beauty of looking for an electronics contract manufacturer that offers post-production services at the onset is that it helps you to enjoy additional services even after the main job has been completed. That way, you will save some money.

10. Pricing

There is no denying that the price or the cost of the product you want to be produced is an important factor that must be considered anytime you are looking to hire an electronics contract manufacturer.

Of course, the pricing or the cost of converting the design to a product depends on several factors. Some of these are the volume or the quantity of the expected product(s), the additional details you want on the product, as well as the manufacturer’s quote.

For that reason, it makes sense that you check with different electronics contract manufacturers so you can have varieties of pricing plans. In the end, you will hire the manufacturer that can offer you what you want at the best rates.

Things to Have in Mind

We commend you for taking the bold step of going abroad to look for an electronics contract manufacturer that can manufacture the electronic products you want.

However, there are some things we will like you to have in mind. The reason why you should have these factors in mind at all times is that they will help save you some avoidable expenses and the potential challenges that may be involved.

The Volume of the Design

It is thrilling to go abroad to get your electronic designs done. However, have you checked to see that the volume is feasible?

It would cost you more to manufacture only a few quantities (say 100 pieces or units) abroad. The cost of shipping and other underlying costs may eat deep into your budget.

The Manufacturer’s Expertise

Once more, you have to pay important attention to the electronics contract manufacturer you want to use.

You wouldn’t want to hire the one that doesn’t have the expertise and accreditation to manufacture for your target market.

Transparency

Finally, you have to make your background checks to be sure that the electronics contract manufacturer can be trusted. The reason is that language and communication barriers, as well as the timeframe for the production, may cause you to get worried.

Therefore, iron out the factors that may stall the progress of the job before you proceed to hire the services of the electronics contract manufacturer.

Final Words

You wouldn’t have any challenges in getting the best electronics contract manufacturer for your next electronics design.

The ideas we just shared will help get you started on the right path so you can get the best manufacturer for the job.

Printed Circuit Boards (PCBs) are manufactured from different types of materials. The general submission is that the sturdiness of the materials used therein determines how sturdy and durable the Printed Circuit Board (PCB) will be.

That informs the reason why many consumers are looking to use the Composite Epoxy Materials (CEM) to manufacture the PCB they want.

Out of all that, there are some classifications and types of CEM that you need to know. These include but are not limited to CEM 1, CEM2, CEM 3, CEM 4, and CEM 5.

Background of the CEM 1 PCB

cem1 pcb manufacturer

The Composite Epoxy Material 1 (CEM 1) PCB is one of the most outstanding out of the others on the list. The reason for that is quite obvious, as you will discover if you will read on.

Generally, Composite Epoxy Materials (CEM) are a group of composite materials that are usually made or manufactured from non-woven glass and woven glass fabric surfaces. After manufacturing or making out of the aforementioned materials, the next step will be to combine the same with Epoxy Synthetic Resin.

When all those have been done, the last step will be to use the CEM in Printed Circuit Boards (PCBs).

What Is CEM 1 PCB?

There are many reasons why you should prioritize the use of the CEM 1 PCB. Of course, those reasons are based on the formulations of the CEM 1 in terms of the design.

Ideally, the CEM 1 PCB is the type of Composite Epoxy Material (CEM) that is low-cost. That implies you will spend less to have it designed for you. That is not leaving out the fact that the CEM 1 PCB is flame-retardant, so it wouldn’t be negatively affected by flames.

Besides, the design of the CEM 1 PCB is patterned in a way that the cellulose-paper-based laminated used in it will have only one layer of woven glass fabric.

What Is CEM 3?

As mentioned earlier, there are different classifications and types of Composite Epoxy Materials (CEMs).

The Composite Epoxy Material 3 (CEM 3) is one of the types of CEM that are competing with the CEM 1 PCB on some fronts.

The CEM 3 PCB is the type that is similar to the FR-4 Material, which is one of the most common and widely used materials for Printed Circuit Boards (PCBs). It is also flame-retardant and white.

That notwithstanding, the CEM 1 PCB has many features and properties that make it outstanding than what the CEM 3 and the others have to offer.

What Is CEM 1 Board Material?

We will like you to understand the different materials and properties that make up the CEM 1 PCB. With that in mind, you will understand the benefits that those materials have to offer when compared to other options like the FR-4 Material.

Excellent Mechanical and Electrical Properties

The effectiveness of a Printed Circuit Board (PCB) is determined by the materials used in it. And because CEM 1 is one of the most important components, it makes sense that the materials should also be of the highest quality.

However, there are some sharp twists here because the materials used on the CEM 1 PCB tend to be fragile. The fragility of the materials is evident when they are compared with the competing FR-4 Material.

That notwithstanding, you tend to save more money when using the CEM 1 PCB because it will only cost you less to produce a one-sided Printed Circuit Board (PCB) using the CEM 1.

Cellulose-Based Composite Material

CEM 1 may belong to the family of Composite Epoxy Materials (CEM) used to manufacture Printed Circuit Boards (PCBs).

However, there are some features and properties that set it apart from the other CEMs. The most outstanding property/component therein is the use of the cellulose-based composite material. That is because it is manufactured from a composite material that is manufactured on a cellulose basis.

Furthermore, the CEM 1 PCB is manufactured by combining two layers of woven glass cloth with phenol compounds and epoxy resin. That is including the fact that the paper cellulose will be placed in between the layers so that the same can be filled with epoxy resin for the formation of the one layer Printed Circuit Board (PCB).

Copper Coating

Curtailing the excessive heating that tends to emanate when the PCB is in motion is an important element that defines the quality of the board.

That is why many consumers are always looking for a Printed Circuit Board (PCB) manufactured using the CEM 1. The reason is not far-fetched from the fact that a CEM 1 PCB has a copper coating, which is an important element for the effective conduction of heat.

The Distinct Features of the CEM 1 PCB

Without a doubt, you have had the cause to question the reason why CEM 1 is one of the most favored Composite Epoxy Materials (CEM) used when manufacturing Printed Circuit Boards (PCBs).

You may not fully understand the reason why that is so if you don’t understand the features and the properties that make it outstanding.

Having said that, here are some of the distinct features and properties of the CEM 1 PCB:

Excellent Flexural Strength

There is no denying that the robustness and the sturdiness of the Printed Circuit Board (PCB) is an important element that must be considered before selecting a PCB to buy.

Consumers that have an eye for detail already know that the flexural strength of the board is an important element that must be considered at all times. And that is where the CEM 1 PCB comes in.

The components of the CEM 1 PCB are reputed for the sturdiness and the excellent flexural strength. That implies these components can keep working and withstand the pressure that may have been exerted by physical stress.

If the flexural strength was not to be in place, there is a higher likelihood that the CEM 1 PCB will break after a few physical stresses have been applied to the board.

Made of Two Layers

The other important element and component of the CEM 1 PCB is the composition using two layers. We must mention that there are some things you need to know about these layers.

For example, the layers are made of woven glass fabric. Out of all that, there is also the addition of an epoxy resin and a paper that is made of cellulose.

Excellent Mechanical and Electrical Properties

The mechanical and electrical aspects of the CEM 1 PCB are also important considerations. The idea here is that those properties further bolster the acceptability of the board.

On the one hand, we have the electrical properties that are there to ensure that the board doesn’t develop some electrical faults after it must have been manufactured.

The mechanical properties, on the other hand, are responsible for enhancing the strength and the sturdiness of the board.

Specially Made for One PCB

There is no need to start looking for the best material that will be used for manufacturing for your next Printed Circuit Board (PCB). Your period of trial and error with PCBs is no over because you have everything you need on the CEM 1 PCB.

What this means is that you are confident that the CEM 1 PCB can produce only one layer of the Printed Circuit Board (PCB).

Electrical Properties of the CEM 1 PCB

We are committed to ensuring that you have the concise details of the CEM 1 PCB. Now, we want you to understand the electrical properties and components that make up any Printed Circuit Board (PCB) that is manufactured using the Composite Epoxy Material 1 (CEM 1).

Energy Conduction and Storage

There is no gainsaying that the excellent transmission of energy and current throughout the board is an important element that must be considered. In that case, we are looking at the use of the energy conducting properties of the CEM 1 to ensure that the board doesn’t lack the energy and current it needs to function.

Aside from that, the other remarkable electrical property of the CEM 1 PCB is the storage of energy. That comes in handy when there is a need to use electric more electric energy.

Transition Temperature

The temperature of the transition is another important aspect of the electrical properties of the CEM 1 PCB.

To give you an idea about that, we will consider it from the perspective that the transition temperature on the board is low. If that is the case, what the CEM 1 PCB does is to become rigid so it can mechanically support the other devices and components connected to the board.

On the other hand, there is a chance that the current temperature on the CEM 1 PCB may go beyond the standard transition temperature. When that happens, the outcome is that the epoxy resin will become viscoelastic. The reason for that is that there is a higher potentiality that the intermolecular secondary bonds will be broken when the temperatures become excessive.

Why You Should Use the CEM 1 PCB

Are you wondering about the advantages and the benefits that you tend to derive if you were to use the CEM 1 PCB?

You don’t have to ponder on that any longer because we got you covered! The reason is that we have figured out some of the major reasons why consumers are always enchanted with the thoughts of using the CEM 1 PCB for their next PCB designs.

Here are some of the advantages and benefits of the CEM 1 PCB:

Support for Components

You don’t have to look farther for a Printed Circuit Board (PCB) that supports the components therein.

You should rely on the CEM 1 PCB because it has all that in-house. The design and the physical strength of the CEM 1 PCB make it easier for the board to lend enough support to the components and parts that are used in manufacturing it.

One-Sided Connection

Many consumers may have believed that the costs of Printed Circuit Boards (PCBs) are only influenced by the quality of the materials. As much as that matters, there is also another important consideration. That is the side that the design of the board is.

Because the CEM 1 PCB is a one-sided Printed Circuit Board (PCB), it will save you some costs. That is because most of the electronic and electrical components are fixated or made on one side of the board. Some of the components that are placed in that direction include but are not limited to:

  • Inductors
  • Resistors and
  • Capacitors

 

Balanced Heating

Balancing the flow of heat on a Printed Circuit Board (PCB) has never been as easy as it is on the CEM 1 PCB.

This circuit board gives a maximum balance in terms of the heating by offering cab store electric energy, as well as providing a better heat dissipation.

Bulk Manufacturing Needs

If you are looking to design and manufacture bulk Printed Circuit Boards (PCBs), the CEM 1 PCB is the one you should rely on. That is because this circuit board is relevant for the production of bulk products, such as remote control, calculators, solid-state drive (SSD), and radio.

Produces Single and Lighter Circuit Boards

Contrary to the popular opinion that Printed Circuit Boards (PCBs) are heavy, CEM 1 PCB is changing that notion.

The CEM 1 PCB is popular because of the way it enhances the production of single-layer Printed Circuit Boards (PCBs) by making the circuit boards to be lighter in weight when compared to the others.

Where Can I Buy the CEM 1 PCB?

You have a thing for electronics and that informed the reason why you are looking to see if there are some electronic assembly jobs you can apply.

Indeed, there are many such jobs because there is always a ready market for electronic appliances. So, it makes sense that you look for the opportunities now that they are still available.

Understandably, you are wondering about the things that may be required of you to become an electronic assembler. You don’t have to bother about that because we have it all figured out.

What Is Electronic Assembly?

Electronic Assembly Jobs

First things first – let us understand what electronic assembly means. It is when you have an idea of what it is all about that you can conveniently look for the jobs that are available in that niche.

Electronic assembly is simply the different processes involved in the manufacturing of electronic appliances. It includes the designing, the prototyping, and the final design of the electronic appliances before they are pushed into the market.

What Does an Electronic Assembler Do?

Before looking for the available electronic assembly jobs, it is pertinent that you understand the job description. There are many responsibilities and expectations that the ideal candidate for the job must meet. That notwithstanding, you need to understand the basic duties of an electronic assembler.

As an electronic assembler, your major job will be to work in a factory or company that focuses on the assembly and production of electronic components and computer parts.

Besides, you will also be responsible for cutting electronic parts, soldering, and routing. It is also important that you abide and comply with the laid down government and industry standards as they pertain to the assembly of electronic components.

How to Become an Electronic Assembler

To qualify for the job of an electronic assembler, there are some things that are expected of you. From education to the experience and other traits, you have many hurdles to scale.

We have gathered and discussed the important prerequisites and requirements that will qualify you for the job of an electronic assembler.

1. Education

As much as electronic assembly jobs have to do with the skills of the candidates, they also have to do with the educational background of the candidates too.

Since both work hand-in-hand, it makes sense that you understand the educational requirements that will increase your chances of being hired as an electronic assembler.

The basic educational requirement here is that you will have a high school diploma. If you don’t have that, some electronic assembly factories may require you to have the equivalent of the diploma for fabricator and assembler positions.

2. Experience

It has become common that different types of jobs require you to have some background knowledge or expertise of the job you are applying for. The same applies when you are looking for electronic assembly jobs – you must have some experience in that regard.

3. Certifications and Licenses

If you are looking for the available electronic assembly jobs near you, the ideal thing you should consider is if you are qualified for the job. The qualification in this instance varies by the electronic assembly company or factory.

For example, some may require you to have licenses, certifications, and registrations in soldering. That is common if you are applying for electronic assembly jobs in the defense and aerospace industries.

By and large, you must have the relevant certifications and licenses so you can qualify for the job. In this case, we are looking at having a certificate in the following regards:

  • Precision Break Certification (PPB)
  • Fabricators and Manufacturers Association, International (FMA)
  • Precision Sheet Metal Operator Certification (PSMO)

 

The overall importance of having the relevant certifications and licensing is that it goes the extra mile to show that you are a professional.

4. Training

You cannot overlook the importance of being trained. When you are trained for the electronic assembly job you are applying for, it will help position you for the job over those that weren’t trained.

Being trained is one thing. The electronic assembly factory being satisfied with your training is another.

In some cases, the electronic assembly factory/company may want to sponsor your training further so you can be in a better position to handle the projects you are about to be assigned.

Have in mind that the employer-sponsored technical training is usually for the advanced and most skilled fabrication and assembly jobs. Also, you must have proven your readiness to be sponsored for such training.

5. Physical Stamina

A lot of stamina is needed in the course of the job. If you aren’t physically fit, it may work against your favor because you may not be able to comfortably withstand the pressure that comes with the job.

It must be mentioned that the job of an electronic assembler often requires that you stand for many hours to get the job done. Of course, someone that doesn’t have enough physical stamina may not have it so good to stand for long hours. And even if you succeed to pull through, you may just be sapped out that you wouldn’t have enough strength to continue with the next electronic assembly job.

6. Technical Skills

Assembling electrical and electronic components has to do with techniques. That is why electronic assembly companies are looking to hire candidates that have the required technical skills.

Talking about technical skills, there are many aspects to focus on. For example, you are expected to have a mastery of the schematics, the technical manuals, as well as the blueprints of the varieties of machines and products that you will come across in the course of the job.

The idea behind the mastery of technical skills is simple. The reason is that you are expected to have an idea of all the requirements that will come in handy to help you aid in the designing and manufacturing of the final products at the end of the entire electronic component assembly.

7. Mathematical Skills

If there is any skill that will further increase your chances of getting hired for electronic assembly jobs, it is the mastery of mathematics. This is imperative at this time that the electronic assembly industry is pushing forward and already incorporating many advanced technologies.

The mastery of the relevant mathematical skills will help you understand the technical undertones of the projects at hand, just as it helps you to use the tools too.

The important areas where the mathematical skills you have will be needed are in the use of computers and other important areas where such skills may be needed.

8. Dexterity

Having an eye for details and stead hands are some of the factors that will help you get employed for the electronic assembly job you applied for.

Electronic assembly factories are always pleased to employ electronic assemblers and fabricators who are not only good at what they do but who also have good hand-eye coordination.

The reason for the requirement of dexterity is because your job as an electronic assembler is because you tend to be handling parts and components that are very small.

9. Physical Strength

There is a difference between the physical stamina you are expected to have and your physical strength. It must be mentioned that the reason why electronic assembly companies prioritize the two is that they are looking to hire electronic assemblers that have the physical attributes that are needed to get the job done.

In terms of physical strength, we are referring to your physical build or strength that will come in when heavy pieces of machinery are to be lifted.

Aside from lifting the heavy components, you may also be required to work in areas that your strength will be a plus. For example, if you are applying for electronic assembly jobs in the aerospace industry, you should have it in mind that you tend to climb ladders and you will also bend when carrying assembling parts.

10. Color Vision

One avoidable mistake in the course of working as an electronic assembler is not being able to differentiate wires. When you make that mistake, there is a higher tendency that you will misplace the wires, which will in turn lead to malfunctioning of the electronic appliance.

That informs the reason why one of the qualifications for electronic assembly jobs is your dexterity at distinguishing colors. When you have an excellent color vision, it wouldn’t be difficult for you to differentiate or distinguish between the wires needed for connecting the electrical components.

 

What Does an Electronic Assembler Do?

There are many duties that you must carry out if you are eventually hired for the electronic assembly jobs you applied for.

Once more, here are the details of the job descriptions of an electronic assembler so you can have an idea of what is expected of you on the job.

Parts Assembly

The first duty or job description you have to work on is how to assembly the parts of the electronics ahead of the final production.

To do this, you are expected to use hand tools or related machinery. Therefore, ensure that you know how to use such tools and machines so you wouldn’t be stuck when the job is handed over to you to handle.

Teamwork

You wouldn’t only be working alone. So, it is time you start cultivating the spirit of teamwork because you will be collaborating with others to get the job done.

Ideally, your job as an electronic assembler demands that you will be working closely with other team members, including engineers and designers.

Quality Control Checks

The quality of the electronic assembly products has a lot to do with quality. That is why many electronic assembly factories are looking to hire electronic assemblers and fabricators that will also help in checking for the quality of the products.

Also, the quality in that instance has a lot to do with the identification of the parts and parts and components that have become faulty.

It is one thing to identify faulty components and parts. It is another thing to fix them.

So, you will also be responsible for fixing or replacing the faulty components as early as possible.

In addition, it is important to carry out quality control checks after a few products have been manufactured. That way, there wouldn’t be many products that were faulty or damaged in the process.

As soon as the replacements or fixtures are made, the next step will be to use the knowledge gathered therein to produce large-scale products as the faults have been detected and fixed on time.

Product Development

This is no doubt one of the most important aspects of the job of an electronic assembler. You will be responsible for developing and building products.

Some of the products you will develop include but are not limited to sensing/sensory equipment, electric motors, electronic control devices, and computers.

Verifying Dimensions and Clearances

The dimensions and sizes of the parts and components used in the electronic products have a lot to do with the success of the design and production.

As an electronic assembler, your duty also extends to verify the dimensions and clearances of the parts used in the products.

In addition to that, you are also expected to verify and ensure that the parts and components used therein conform to the specifications of the blueprint. To confirm this, you will use tools, such as height gauges, micrometers, and calipers.

Inspection

The job description of an electronic assembler also includes the inspection of the products that were manufactured.

When it comes to this, there are specific aspects where your inspection is needed. At the core of the inspection is that you will have to check to see that the circuits, the installations, and the assembly of the parts/components were done in the right way.

Final Words

The job of an electronic assembler is a critical one. You will among many other things be responsible for ensuring that the products are of good quality and that the parts and components used in them are installed in the right way.

We are confident that you have gotten the insights you are looking for so you can easily spot the viable electronic assembly jobs that you can handle.

The role played by Printed Circuit Boards (PCBs) in the electronics industry cannot be downplayed. It is because of the use of PCBs in the design and manufacturing of those appliances that it became easier for the wires and other components to be well structured.

At the same time, it has become obvious that there are some upgrades and innovations in the global PCB industry. It has now led to the disparities in the types of PCBs, which in turn, aids in the selection of the best circuit board for the job.

What Is a Single Sided PCB?

single layer pcb

The single-sided Printed Circuit Board (PCB) is one of the most used types of circuit boards. We want you to understand what this type of circuit board has to offer and which makes it better than the others.

This content also explains why the single-sided PCB is better than its competitor – the double-sided PCB.

The single-sided PCB is a type of circuit board that has the component/spare parts layered on one side while the circuit is layered on the other side.

As much as the single-sided PCB is restricted in the circuit design because of the one-sided conductor, it still plays a vital role in the low-density use cases.

Benefits of Single-Sided PCB

There are many reasons why customers are using the single-sided PCB. And PCB manufacturers are always ready to offer that service because of the benefits that they also derive in the process.

Here are some of the key features and benefits of using the single-sided PCB in your next circuit board design.

1. No Overlapping

The first reason why the single-sided PCB is better is that there is no lapping when it is used.

Because this circuit board has one conductive layer, it becomes easier to prevent the conductive paths from overlapping or cross over one another.

2. Suitable for Low-Density Designs

Many Printed Circuit Boards (PCBs) are used for high-density designs and applications. But, things get a little bit better when you are using the single-sided PCB.

It is because this type of circuit board is suitable for low-density designs and applications.

3. Used for Simpler Applications

It is not out of place to use Printed Circuit Boards (PCBs) to design and manufacture different types of electronics.

However, it is pertinent to extend the same applies to other types of use cases. That brings us to another use case of the single-sided PCB. This circuit board is used for simpler applications.

Some of the potential applications and use cases of the single-sided PCB:

  • Timing circuits
  • Low-cost devices like calculators
  • FM radios
  • Power supplies
  • Light Emitting Diode (LED) lighting boards

 

4. Simplified Design

It is pertinent to mention that the simplicity of design is something of utmost consideration when designing a Printed Circuit Board (PCB).

That informs the reason why the single-sided PCB is one of the most used types of the circuit board. It has a simplified design that makes it ideal for application in different use cases.

5. Faster Production

The other reason why the single-sided PCB is better than the other types of Printed Circuit Boards (PCBs) is because of the faster production.

That way, it becomes easier for the PCB manufacturer to design and produce the circuit board in the shortest time possible.

6. Higher Volumes

Producing more circuit boards at the speed of light is another benefit that the single-sided PCB has. Hence, the manufacturer can process your high single-sided PCB orders in real-time.

7. Reduced Costs

You don’t have to break a bank anytime you want to design a Printed Circuit Board (PCB).

The single-sided PCB has one of the most affordable costs.

Single-sided PCB vs. Double-Sided PCB

There have been debates bordering on the differences that exist between the single-sided PCB and the double-side PCB. An overview of the two circuit boards shows that the major difference is on the number of circuit boards and the components thereof.

Aside from that, there are many other reasons why the single-sided PCB is better than the double-sided PCB.

Here are some of the differences between the two:

Number of Components

The single-sided PCB has the components and spare parts mounted on one side of the circuit board.

However, there are more components and spare parts in the double-sided PCB. In this case, the double-sided model enables the mounting of the components and conductive copper on both sides of the circuit board.

Complexity

It doesn’t take more time than required to produce the single-sided PCB. That is because the circuit board isn’t complex.

However, more complexity is tenable when manufacturing the double-sided PCB. It is partly because of the need for more complex use cases and mainly because of the production demands more efforts.

Funding

If you are looking at manufacturing a Printed Circuit Board (PCB) that doesn’t cost much, the single-sided PCB is the one to go for.

On the other hand, you may need to spend more funds to design and manufacture the double-sided PCB.

A Guide on How to Choose a Single-Sided PCB Manufacturer

We will now consider one of the most important aspects of the single-sided PCB. That is the manufacturer that will handle the job.

More often than not, some PCB manufacturers may not successfully design the circuit board as you wanted. It may because the manufacturer doesn’t have the expertise to deliver what you want. It can also be that your expectations are unrealistic at the immediate time.

Whichever is the case, you must understand that you need to learn how to select and choose the best single-sided PCB manufacturer for the job.

Below are the criteria and the things you must look for before deciding on the PCB manufacturer that will handle the project:

1. The Manufacturer’s Reputation

The first thing you must have in mind is the reputation of the manufacturer. If the manufacturer has some shady deals in the past, it wouldn’t be long before you discover that.

A serious background check must be done so you will discover some of the reasons and credentials that make the single-sided PCB manufacturer qualified for the job.

Here are some of the ways you can check and confirm the reputation of the single-sided PCB manufacturer:

Credential Verification

The first thing you must check for is the credential of the PCB manufacturer. It will make more sense if you have an idea of the latest credentials and certifications in the PCB industry so you will check if the manufacturer has the same.

The verification of the credential helps you to understand if the single-sided PCB manufacturer has met all the conditions that are required before taking to PCB design.

Past Designs

In some cases, the single-sided PCB manufacturer will allow you to see the catalog and the list of PCB designs it handled.

You want to go through the past designs to confirm if the manufacturer can deliver the quality you expect on the job.

Factory Visit

Depending on the agreement you have with the single-sided PCB manufacturer, you may be allowed to visit its factory.

The visit allows you to have an on-the-spot assessment of how the manufacturer goes about the design.

If you are satisfied with what you see, it means you can rely on the manufacturer to do justice to your single-sided PCB design.

Otherwise, you may have to look for another single-sided PCB manufacturer that will offer you the design you expect.

2. Lead Time

It is not out of place for some single-sided PCB manufacturers to claim to offer the best lead time. That isn’t always the true position of things because some times, the design may take longer than expected.

What Is Lead Time?

So, what does lead time mean? Lead time, simply put, is the amount of time or the duration it will take before the single-sided PCB will be designed and manufactured.

What Influences Lead Time?

We must mention that in this time of automation, many types of equipment are often channeled to make PCB designs and productions faster.

As much as those will facilitate the design, more efforts should be put in by the manufacturer.

By and large, there isn’t much to worry about the lead time of the single-sided PCB. It is because this type of circuit board doesn’t take more time to manufacture because of the less-complex design.

The shorter lead time of the single-sided PCB also implies that it can be synthesized in a few days and made available to you.

Nevertheless, do not relent to select the best single-sided PCB manufacturer based on the lead time. You would want to go for the manufacturer that offers the shortest lead time without having to compromise or reduce the quality of the circuit board.

3. Circuit Design

Indeed, the single-sided PCB doesn’t always require a complex design. That doesn’t in any way imply that it will always be easy to design.

Instead, the nature of the circuit has more roles to play in the complexity of the single-sided PCB. That is why you want to use the circuits with simplified layouts, as they make the job faster and easier.

4. Component Sourcing

Who will be responsible for sourcing the components of the single-sided PCB? Will you be the one to do that or will the manufacturer have to handle it?

While some single-sided PCB manufacturers will offer to source the components, others may not. If you are lucky to get the one that can source the components, do not leave it at that. Instead, proceed to enquire about where and how the components will be sourced.

Having an idea makes it a lot easier for you to figure out if the single-sided PCB manufacturer has the capacity to source and use the best components and parts for the circuit board design.

5. Budgetary Constraints

What is your budget like? Can you afford to pay for the services of the single-sided PCB manufacturer?

Of course, this type of circuit board doesn’t cost as much as the double-sided PCB does.

Aside from the general overview that the cost factor for the single-sided PCB is lower, you must also check other things. The additional specifications you may have and the numbers of units you want to be manufactured are some of the factors that influence the cost of the single-sided PCB.

6. Delivery Timelines

Time is of the essence and you mustn’t overlook that when selecting the best single-sided PCB manufacturer.

You are looking at the delivery timelines and how long it will take the manufacturer to design, manufacture, and ship the circuit board to you.

Of course, you may have set a timeline you expect the board to get you. So, ensure that the single-sided PCB manufacturer can deliver the circuit board on time and in good condition too.

7. Quality

What is the quality of the single-sided PCB? If the circuit board doesn’t have the quality you expected, it may be a waste of time and resources.

Of course, you can always determine the potential quality of your single-sided PCB by checking some of the designs that the manufacturer did for the other customers.

8. Reviews and Recommendations

One important consideration that many people tend to overlook is the reviews and recommendations of previous clients.

The rule is simple – if a single-sided PCB manufacturer has more positive reviews and recommendations, it means that it is doing a great job. However, more negative reviews are an indication that the manufacturer should be avoided.

Some single-sided PCB manufacturers have a “Testimonial” page or section on their websites where you can check to see the reviews and thoughts of the previous customers. You may also check on the manufacturer’s social media handles and pages to see what the customers have to say too!

9. Aftercare Services

One of the best ways to select a single-sided PCB manufacturer is by checking to see if it offers aftercare services.

The essence thereof is to see if the manufacturer can offer to repair the circuit board if it develops some issues.

Interestingly, the single-sided PCB is easy to repair in case something goes wrong in the circuit board. So, tracing and fixing the issues wouldn’t be a problem.

Conclusion

The single-sided PCB is not complex and it can be used in many applications. The key to enjoying what this circuit board has to offer is to get the best single-sided PCB manufacturer.

The details we covered in this content give you a headstart on what the single-sided PCB is all about, and how you can select the best manufacturer.

What are the services you expect your favorite single-sided PCB manufacturer to offer?

The post 10 Tips For A Good 6 Layer PCB Manufacturer appeared first on Swimbi PCB.

]]>
Printed Circuit Boards (PCBs) are growing in popularity because of the flexibility they offer to electronic appliances. So, when the 6 layer PCB is brought into focus, it means the use cases will be higher.

What Is a 6 Layer PCB

6 layer pcb

The 6 layer PCB stackup is the type of Printed Circuit Board (PCB) that uses 4 layers. This may seem surprising considering that the name implies 6 layers. However, that is not always the case because the 6 layer PCB has a variation to it.

By and large, the 6 layer PCB stackup is a circuit board that has 4 layers attached to the board while two additional layers are added between the planes.

Design of the 6 Layer PCB

It must be mentioned that there are some specific requirements to be met before the 6 layer PCB can be actualized.

The first consideration is the classic stackup that has to do with the four (4) routing layers. These layers are divided into:

  • Two internal layers
  • Two outer layers

The other two layers that make up the 6 layer PCB prototype are used between the internal planes. These are the use of one of the layers in the power and the other on the ground of the circuit board.

It should be noted that the overall impression of the 6 layer PCB is geared towards facilitating the viabilities of the circuit board. Ideally, the EMI will be drastically enhanced and improved when the 6 layer PCB is used. Some of the ways it is done are by:

  • Delegating two surface layers that will be used for routing low-speed signals
  • Offering two buried layers that help release high-speed signals

 

Variations in the 6 Layer PCB

As much as the 6 layer PCB has many potential benefits and use cases, there are also some cases where the actual design may not be tenable. Instead, there are two major variations to the use of the 6 layer PCB.

The first variation is that it that the circuit board’s route traces will be routed to the adjacent routing layers on a perpendicular basis. It is because of it that the 6 layer PCB tends to have minimal crosstalk and increased routing efficiency.

The other variation stems from the speed of the 6 layer PCB. If you are considering the high-speed designs, for instance, it means you will have to keep the ground and power planes on the adjacent layers. While that aids in decoupling, the additional ground planes may also be used for shielding the designs that may require low electromagnetic emissions.

Tips to Help You Choose a 6 Layer PCB Vendor

Are you ready to design your next 6 layer prototype? You will need a PCB manufacturer/vendor that has been in that field for many. The vendor also needs to have a mastery of the different concepts that will make the design great.

Finding a good 6 layer PCB manufacturer isn’t always an easy task. You will continually check through the hundreds of manufacturers, comparing their services against the other.

But, if you are ready to save the time and efforts to go through that long track, we are ready to help you.

We have come up with important features and considerations that you must always have in mind when you want to choose a 6 layer PCB manufacturer. Here are some of those tips:

1. Instant Quotation

Nobody has all the time in the world. You certainly don’t have that too. And even if you had some time to spare, you wouldn’t want to use it to beat around the bush.

The first thing you should be looking for is the availability of instant quotes. More often than not, the 6 layer PCB manufacturer has a section on the website where you can enter the details of the design for a breakdown of the costs.

Here are some of the requirements and details you will be required to enter to get a quote:

  • Quantity or the number of 6 layer PCB you want to be designed for you
  • The thickness of the circuit board
  • The number of layers you want. Because this is a 6 layer PCB, you should select 6 layers and not 4 layers.
  • Dimensions of the circuit board (height x width)

 

2. The PCB Layout

The success of a 6 layer PCB design is partly because of the manufacturer’s expertise and mainly because of the layout of the board. If the circuit board wasn’t laid out the way it should, it wouldn’t be long before issues will start coming up.

It is for that reason you must consider the design of the 6 layer PCB layout, as it plays an important role in the success of the design.

To inspire you, here are some of the important aspects of the PCB layout design that you must focus on at all times:

DFM Team

This has a lot to do with the manufacturer. If the manufacturer can’t deliver on the job, don’t use its services.

But, how will you know a manufacturer that can deliver the best 6 layer PCB layout design? It is simple! Check to see if the manufacturer has a DFM team, which is the team that will manufacture the design you want.

Types of Vias

While vias play an important role in the design of a 6 layer PCB, too much of it may not be ideal.

Sometimes, the manufacturer may want to try many things at different times by using many types of vias in your 6 layer PCB.

That shouldn’t be the case because the diversification and overt use of the vias may make the design awkward. Instead, aim to use the services of a 6 layer PCB manufacturer that uses minimum vias for the 6 layer PCB design.

PCB Stack-Up

PCB Stack-Up implies the trade-off or the advantage between the layer count and the fabrication process.

Always aim to have a PCB Stack-Up that aligns with the cost targets, desired reliability, and yield of the circuit board.

3. Thermal Relief

There is no denying that there may be a need to get some thermal relief if the circuit board becomes too hot. Of course, you may not always actualize that if you hadn’t figured it out from the onset.

It must be mentioned that issues that have to do with the terminals/thermal points of the 6 layer PCB may cause great damages.

There are many ways to curtail excessive hotness on the 6 layer PCB. Here are some of them:

Sufficient Spaces

Is it possible to have more spaces in a Printed Circuit Board (PCB) considering that the boards are now getting smaller?

Yes, it may be possible if the 6 layer PCB manufacturer has expertise in that regard. What is required is to create more and sufficient spaces around those areas that tend to get hotter with time.

Have in mind that the reason for the increased hotness is because the current passing through the traces gets higher with time.

Besides, having more space on the circuit board is a must because the more space is available, the more the heat will have enough area to cool off.

4. Single Point of Contact

It is time you stopped searching for different hands to help you manufacture your 6 layer PCB. Instead, aim to have a single point of contact or a one-stop-shop whereby the manufacturer will handle the design from the start to the finish.

Here are some of the reasons why you should use only one 6 layer PCB manufacturer:

Eliminates Communication Barriers

The first reason for selecting one 6 layer PCB manufacturer is that it helps to eliminate communication barriers.

If you were using different manufacturers, the potentialities of confusion tend to be many. That is because you will keep trying to get information from different angles and using the same to inspire the other party.

Fewer Modifications

Modifications are paramount when there must have been some errors in the course of the PCB design.

While it may not be entirely ruled out, it can be reduced when only one hand is working on the design. Also, if the 6 layer PCB manufacturer is handling the design and manufacturing, it becomes a lot easier to spot the errors on time.

Fixing those errors and making the needed modifications wouldn’t be a mirage, as everything is done in-house.

5. Component Sourcing

Most times, customers believe that a 6 layer PCB manufacturer offering one-shop services should also handle the component sourcing. While that is usually the case, you needn’t leave it all to the manufacturer.

Rather, consider taking the time to check how the component is sourced, as you may need to do it yourself sometime. At the same time, ensure that the manufacturer or designer of your 6 layer PCB is using the right type of component on the circuit board.

6. Power and Signal Integrity

If the integrity of the signal and the power is not optimum, there is a likelihood that the design of the 6 layer PCB may not come off as expected.

So, what can be done about it? It is to bolster the power and signal integrity. Here are ways to go about it:

Check the Aspects

The first step is for the engineer designing the 6 layer PCB to check the aspects of the circuit board.

Here are some of the aspects that ought to be checked:

  • Terminations
  • The rise and fall of the signal times
  • Characteristic impedances
  • The drivers’ slew rates
  • Drive strength
  • Track lengths

 

DC and AC Performance

The integrity of the power is mostly buoyed by the performance of DC and AC. You want to check to see if the overall performance of the DC and AC in the power distribution network is optimum.

Integrity Simulations

There may be no better time to check the integrity of the power and signal than before the commencement of the design.

The ideal way to do that is by performing the signal integrity simulations during the pre and the post layout of the 6 layer PCB.

7. Component Placement

How the 6 layer PCB manufacturer places the components is another point of concern.

We understand that different PCB manufacturers have different approaches to mounting the components on the circuit board.

However, the standard placement model mustn’t be deviated from because that may alter the outcome of the design.

In light of that, here is the ideal way of placing and mounting the components of the 6 layer PCB:

  • The connectors should come first
  • The power circuits should follow
  • The precision circuits will be mounted followed by the precision circuits
  • After all those aforementioned components have been mounted, the other elements and components will follow suit.

 

8. Cost

What is your budget for the 6 layer PCB design? More often than not, the budget you have is only a placeholder because the actual costs may be higher than what you set aside.

Despite that, you will want to select and use the services of a 6 layer PCB manufacturer whose costs of the design and manufacturing is closer to what you budgeted.

9. Turnaround Time

How long will it take the manufacturer to design the 6 layer PCB, manufacture it, and send the same to you?

That is why you must consider the turnaround time, especially when you want to take delivery of the 6 layer PCB as soon as possible.

10. Mode of Delivery

How flexible and efficient is the delivery system of the 6 layer PCB manufacturer? Some of those manufacturers have an ongoing relationship with logistic companies like FedEx, which enables them to dispatch the circuit boards in time.

By and large, aim to choose a 6 layer PCB manufacturer that can deliver the circuit board within five (5) business days.

Conclusion

The 6 layer PCB brings more flexibility and applications to the areas you intend to use it.

Ensure that you are outsourcing the design and manufacturing of the circuit board to a PCB manufacturer that can deliver the best quality and at affordable costs too!

The 8 layer PCB has seen a tremendous rise in the use cases in recent times. It must be mentioned that the application of the 8 layer PCB stackup is broadening as the days go by because the circuit board can be used for many things.

In this article, we aim to help you understand the meaning of the 8 layer PCB. You will also learn about the prototyping, the guidelines, and the factors that will help you get the best designer.

What Is an 8 Layer PCB?

8 layer pcb factory

The first thing we want you to understand is the meaning of the 8 layer PCB. When you understand all there is to this circuit board, it will be easier for you to comprehend how it functions.

The 8 layer PCB stackup is a type of Printed Circuit Board (PCB) that has the layers firmly stacked. The stacking goes on to create a formidable dependable and predefined mutual connection among all the layers on the board.

It must be noted that the procedure of designing and producing the 8 layer PCB stackup isn’t as easy as mounting the components. Instead, a complex manufacturing procedure is always used to design the circuit board.

8 Layer PCB Prototype

The prototype of the 8 layer PCB isn’t something that takes more time than required. Instead, the designer or PCB manufacturer needs to have an eye for details to make the design work out as planned.

Because of the complexity of the structure, it may take some time before the design of the 8 layer PCB will be completed.

Having said that, here are some of the steps that are required when creating or designing the prototype of the 8 layer PCB:

Impedance Control

Isolation and Impedance Control is needed on the traces because of the roles that play in the overall success of the 8 layer PCB design.

In that case, the use of the Isolation and Impedance Control is required for those analog signals that require RF.

Prevention of Noise Decoupling

Noise decoupling is an important aspect that must be considered when designing an 8 layer PCB.

It is important to prevent that and the best way is to create a digital ground plane. It is in this ground plane that the multiple power and ground planes will be designed and deployed via the 8 layer PCB stackup.

Layer Matching

The layers in the 8 layer PCB must be matched. The ideal way of going about that is by creating more layers that will be used in aiding routing signals.

Signal Shielding

Signals ought to be shielded from one another to prevent loss of signal and infractions.

That informs the reason why the 8 layer PCB is the best circuit board in that regard. It provides more planes, which, in turn, will be used for shielding signals from the other signals on the adjacent layers.

Guidelines to an 8 Layer PCB Stackup

There are some guidelines and prerequisites to be met before the 8 layer PCB can be deployed.

Here are the different guidelines that aid the successful use of this type of Printed Circuit Board (PCB):

Improving EMC Performance

The first guideline of the 8 layer PCB is that the performance of the EMC will be improved tremendously.

Sometimes, that improvement is tenable when additional planes are added to the circuit board.

More Routing Layers

The addition of more routing layers is the other aspect of the 8 layer PCB stackup. In this case, the 8 layer PCB is used to add more routing layers (usually two) so that the same will be used to enhance the performance of the EMC.

Configuration of an 8 Layer PCB Stackup

There has been some confusion over the configuration and outlook of the 8 layer PCB. When you understand that, it becomes a lot easier for you to find out how the circuit board looks like after it must have been designed.

Four Layers and Four Planes

The 8 layer PCB stackup doesn’t have eight (8) layers as many customers may have presumed. Instead, the circuit board consists of four planes and four layers.

Better EMI Control

Having better control over the EMI is another aspect of the 8 layer PCB configuration. The idea is to make it easier for the functions and operations of the circuit board to be well controlled.

Aside from that, the signal integrity of the design will be improved and increased when that is put into consideration.

The composition and configuration of the 8 layer PCB go on to create signal layers that are separated by the ground planes and the power planes. The role of those planes is to increase the strength of the signals by reducing the crosstalk between the signal layers.

Below is how the 8 layer PCB tends to look like at the end of the design:

  • Top layer
  • Prepreg
  • Ground plane
  • Core
  • Inner Layer 1
  • Prepreg
  • Power plane
  • Core
  • Ground plane
  • Prepreg
  • Inner Layer 2
  • Core
  • Power plane
  • Prepreg
  • Bottom layer

 

Best Practices for an 8 Layer PCB Stackup Design

8layer pcb stackup

There are some techniques and best practices that must be adhered to anytime you want to design the 8 layer PCB.

Here are some of those techniques and the roles they play:

1. The Direction of the Routing

The first technique is to master how to route the layer. More often than not, there may be some mix-up in routing the signal layers.

The ideal way of going about that is by using perpendicular routing to route the signal traces on the adjacent layers. Doing that ensures that the risks of crosstalk will be minimized.

For added effect, consider routing the signal layers differently on the subsequent layers. This is despite the separation of those layers by the ground and the power planes.

2. Buried or Blind Vias

More space can be created on the 8 layer PCB for routing only if the right machinery is in place. That machinery is to use the buried or blind vias.

However, not all 8 layer PCB manufacturers and designers have the tools to make this work. So, you want to confirm with the designer if the buried or blind vias option can be used in designing your 8 layer PCB stackup.

3. Return Path

The Return Path can make or mar the outcome of the 8 layer PCB design. So, it is pertinent that you understand how the Return Path is designed to work on the circuit board.

The rule of thumb is to ensure that the 8 layer PCB has a short Return Path. This does not only help to reduce the risks of interferences with the other components. It is also helpful in facilitating high-speed signals.

4. Ground Plane

As much as the ground plane helps to create the needed signals, it must be designed in the right way.

Ideally, the best way of designing the ground plane is to ensure that it isn’t split. A split ground plane can create impedance discontinuity on the 8 layer PCB stackup.

Aside from ensuring that the ground plane isn’t split, also check to see that the outer layer components have low impedance. That is especially considered when the impedance is connected to the inner ground planes via the vias.

The Cost Considerations for an 8 Layer PCB Stackup

Designing an 8 layer PCB costs money. It makes sense that you have an idea of the rough estimate of what it will cost you so you wouldn’t be disappointed when the costs exceed what you budgeted.

Below are some of the cost-affecting factors that contribute to the increase in the cost of designing the 8 layer PCB stackup:

Number of Layers

The first consideration is the number of layers that the Printed Circuit Board (PCB) has.

Contrary to the popular opinion that the 8 layer PCB has eight layers, it instead has four. The other four components are the four planes.

Size of the Board

The size of the board has to do with the components therein. The more components are packed into the board, the more the size increases.

The 8 layer PCB stackup board size increment can contribute to an increase in the cost of designing and manufacturing the circuit board.

The Size of the Holes

The size of the holes on the 8 layer PCB is another important factor that can influence the costs of the circuit board.

We will look at this from two perspectives. The first perspective dictates that the more holes are needed on the board, the higher the costs of design and production. The other perspective has to do with the use of super-thin holes that require more work before the board will be produced.

Type of Finish

Despite being designated a minimal factor, the type of finish used in the 8 layer PCB can increase the costs.

Of course, you have many options when it comes to this. You may want to use the type of finish that offers a longer shelf life or another that has a higher grade.

Here are some of the most popular types of finishes used on the 8 layer PCB stackup:

  • ENEPIG: This type of finish is used because of the solderability, the contact-surface, and the AI Wire bondable feature.
  • HASL
  • IMM Ag
  • OSP
  • Elec Au
  • LFHASL
  • ENIG
  • IMM Sn

 

Custom Specifications

More often than not, some customers will want the 8 layer PCB to have some specific configurations and specifications to make their design unique.

Of course, if this is to be considered, it means more expenses will be made, as the manufacturer has to take more time to work on the project.

Therefore, as you are coming up with the custom designs and specifications for the 8 layer PCB stackup, ensure you have some more money to spare.

Thickness

The thickness of the 8 layer PCB has to do with the materials used to enhance the sturdiness of the board. If you are considering this, have in mind that the thicker the circuit board gets, the more costs it will attract.

In the same regard, the type of materials used for the design can contribute to an increase or a decrease in the thickness of the board. If the materials aren’t too thick, you may spend less.

How to Find the Best 8 Layer PCB Stackup Designer

Finding and using the services of a good 8 layer PCB manufacturer is a matter of patience. You must be careful about how you go about that so you wouldn’t have to get the design that you didn’t expect.

Here are some of the factors and the things to look for when looking to hire an 8 layer PCB manufacturer:

1. One-to-One Service

You might want to use the same PCB designer for all your 8 layer PCB stackup needs. That way, you are confident that the design will be facilitated in real-time and at affordable costs too.

Besides, an 8 layer PCB manufacturer/designer that offers a one-stop service helps to source the materials and get all the specifications ready for immediate design, manufacture, and dispatch.

2. Professionalism

You wouldn’t want to use an 8 layer PCB manufacturer that doesn’t have the relevant experience and expertise.

Aside from the professional undertone, you must also consider the certifications the manufacturer has, as that will help you make an informed decision.

3. Order Capacity

Does the 8 layer PCB manufacturer have the capacity to deliver the project and on time?

You must also check to see if the manufacturer/designer can take the minimum quantity that you want to design and manufacture.

4. Turnaround Time

Can the 8 layer PCB manufacturer facilitate the design and manufacture of the circuit board in a few weeks?

If that’s not tenable, can the manufacturer be able to deliver the design in good condition at the time you need it?

Find out with the 8 layer PCB manufacturer you want to use if the turnaround time is feasible.

Final Words

Finding an 8 layer PCB manufacturer/designer for your next project/design wouldn’t be a herculean task after all.

The tips we shared will help you in making an informed decision on what to expect on the 8 layer PCB and how you can get the best designer/manufacturer for the job.
