With the massive acceptance of the Surface Mount Technology (SMT) and chip components, there has been a massive surge in the use of Printed Circuit Boards (PCBs). Now, many PCB manufacturers are looking for ways to integrate the Ceramic Printed Circuit Boards (PCBs) into their list of services.

You may have heard about Ceramic PCBs and the tremendous impacts on the electronics manufacturing processes. But, you are yet to understand what it means let alone knowing how to choose the best Ceramic PCB manufacturers.

In this article, we will show the length and breadth of the Ceramic PCB starting from the meaning to the advantages and down to how to select the manufacturers.

What Is Ceramic PCB?

ceramic pcb

The Ceramic PCB is the type of Printed Circuit Board (PCB) that is designed with a ceramic base. The design of this type of PCB also makes it possible for Ceramic PCB to fit into the structure of the entire circuit board without compromising on the performance.

The most outstanding feature of the Ceramic PCB is the printing of the conductive pathways on the materials used on the circuit board. That way, there wouldn’t be any hitches as there could have been if the pathways were printed on the circuit board.

Moreover, the Ceramic PCB is famed for the excellent heat dissipation that because of the high thermal conductivity and the minimal expansion coefficient (CTE).

Ceramic Substrate vs. FR4 Material

The glass fiber (FR4) Printed Circuit Board may have its advantages, but it is not a strong competitor to the ceramic substrate PCB.

So, what makes the Ceramic PCB better than that of the traditional PCBs made from FR4 materials?

The major reason why the Ceramic PCB is better than the other made from the FR4 material is because of heat dissipation. The higher thermal conductivity it has and the overall performance of the Ceramic PCB makes it easier for heat to get in touch with other components of the circuit board.

Types of Ceramic PCBs

Ceramic Printed Circuit Boards (PCBs) come in different sizes and shapes. It is the types of Ceramic PCBs that we want to consider so you will learn about the different ways they function.

Thick Film

The essence of the Thick Film Ceramic PCB is to make it easier for the copper to be protected from oxidation.

It must be mentioned that this singular feature sets the Thick Film Ceramic PCB apart from what we have in the traditional PCBs because of the advanced thickness and protective tendencies.

Low Temperature Ceramic PCB

This type of Ceramic PCB is noted for the higher thermal benefits that it has to offer.

Because of that, the success of the Low Temperature Ceramic PCB (LTCC) is because of the low temperature that it uses. And that is because of the evolutionary shrink tolerance and the less warpage.

High Temperature Ceramic PCB

The last but not the least is the High Temperature Ceramic PCB. Aside from the advanced temperature, this type also uses some of the best materials, such as aluminum oxide, plasticizer, mixing adhesive, and solvent mixed with raw ceramics.

Why Should I Design Ceramic PCB?

You may be wondering why you should use the Ceramic Printed Circuit Board (PCB) in the first place.

Below are some of the reasons and advantages that the Ceramic PCB has over the traditional FR-4 material:

1. Higher Insulation

The first reason why the Ceramic PCB has more advantage over the traditional Printed Circuit Boards (PCBs) is because of the superior insulation. Getting this insulation is important because anything short of that can cause the Ceramic PCB to suffer from any voltage issues.

First, the Ceramic PCB offers higher and superior insulation because of the ability to withstand the inconsistencies that tend to emanate when the voltage fluctuates.

The second reason why the superior insulation is better is because of the proper insulation given to the electrical resistance properties.

2. Superior Thermal Conductivity

The ability to transfer heat effectively is another reason why the Ceramic PCB offers better precision than the traditional PCBs do.

When looking at the high-quality thermal conductivity, the focus is usually on the excellent transfer of heat. Because heat tends to damage the circuit board if not effectively transferred, it makes sense that the superior thermal conductivity offered by the Ceramic PCB is commendable.

The trio of Beryllium Oxide, Aluminum Oxide, and Aluminum Nitride are the core values of the superior thermal conductivity provided by the Ceramic PCB.

3. Low Dielectric Constant

When a Printed Circuit Board (PCB) works in a high humidity environment and under higher temperatures, the functionality might be low.

It is in consideration of it that the low Dielectric Constant (DK) of the Ceramic PCB is there to help. What it does is to keep the Ceramic circuit board to keep functioning effectively even when the temperature and humidity are high.

4. Long-Lasting

You wouldn’t want to design and manufacture a Printed Circuit Board (PCB) that may end up not lasting for many years. If that happens, you will have to spend more money to either fix the issues or to design another.

Considering that, the Ceramic PCB is there to help with the long-lasting and durable effects. It is designed in a way that the circuit board can withstand and work well under extreme pressure and heat.

5. Multiple Layer Support

Integrating or adding more layers to a Printed Circuit Board (PCB) may not be a daunting task if there were support for multiple layers.

The Ceramic PCB has an easy multi-layering that allows for the integration of more layers into the circuit board. That is in addition to the high mechanical strength of the board that enables the support for multiple layers, which means handling complex work.

6. Compact

Printed Circuit Boards (PCBs) needn’t be extra-large or bigger before they can function. Sometimes, being small and compact is the key to enable the support for complex tasks.

Because the Ceramic PCB is smaller and compact, it becomes easier to integrate it into different use cases without bothering about the space it will take up.

7. High-Quality Materials

The quality of the materials used in designing a Printed Circuit Board (PCB) also matters. And if you are not sure of the right type of sturdy materials, some offer better performance.

Most of those high-quality PCB materials are used on the Ceramic PCB. From aluminum oxide to aluminum nitride, these materials are designed to offer higher conductivity and withstand a high amount of heat.

8. Adaptability

Another reason why the Ceramic PCB is preferred over the traditional FR4 material is because of the adaptability. It means that the board can be used for many industrial purposes.

For example, the adaptability features make it easier for the Ceramic PCB to offer a higher wear resistance and mechanical stiffness.

9. Versatility

Ceramic PCBs aren’t limited to one or a few use cases. Instead, the use cases are many thanks to the versatility of the circuit board.

That informs the reason why the Ceramic PCB is used in many high-powered applications. Some of the use cases are:

  • Use in high-powered Light Emitting Diodes (LEDs)
  • Applying the Ceramic PCBs in devices that require extreme precision and higher heat emission.

 

Guide to Choosing the Best Ceramic PCB Manufacturer

If you were to design a Ceramic PCB, you will be looking for the best manufacturer to handle the job for you.

In light of that, you must look for the best Ceramic PCB manufacturer that has an eye for details, mastery of the process, and fast turnaround time.

Below, we have shared some of the helpful tips that will lead you by the hand until you locate the best Ceramic PCB manufacturer that will handle the job.

1. Laser Drilling Technology

As the Printed Circuit Boards (PCBs) industry continues to evolve, it is opening up the opportunities for the addition of the use of relevant technologies.

Laser drilling technology is one of the latest and most used technological advancements that aid in the manufacturing process of the Ceramic PCB. So, it makes sense that you base your search for a Ceramic PCB on that.

Here are some of the benefits and the reasons why laser drilling technology is a better option for designing Ceramic PCBs:

  • No pollution
  • Environmental protection
  • It offers higher precision
  • Large-scale batch punching
  • High speed

Laser drilling technology is also widely used because of the interoperable use of both soft and hard materials.

2. Application Fields

Some Ceramic PCB manufacturers have some application fields that they tend to perform better. So, if you already have an idea of the potential use case or application field of the Ceramic PCB, you will find it easier to check the manufacturer that can meet that need.

Here are some of the application fields and use cases of the Ceramic PCB:

  • Multi-layer interconnect board
  • Memory module
  • Transmission module

 

3. Conductor Materials

Have you figured out the materials that will be used in constructing the board of the Ceramic PCB?

If you haven’t, there are many options out there, and each of them has specific use cases and advantages.

First, Ceramic PCBs with silver traces are ideal if you are working on a budget. The only major downside to using the silver trace conductor materials is because of the non-durability; meaning that it can get damaged after a while.

The gold-plated conductor materials are sturdier and tend to last longer than the silver traces would. You only have to spend more money to get this type of conductor material.

4. Type

Another important aspect of the Ceramic PCB is to select the type that you want. There are two major types. When you understand how these works, it wouldn’t be difficult for you to select the PCB manufacturer that will offer you the service you need.

The first type of Ceramic PCB is called the Direct Copper Bonded (DCB) Ceramic PCB. This variant is ideal if you are not looking at the size of the PCB alone. It allows you to etch the circuit board into different layouts.

On the other hand, you might want to design the Thin-Plate Ceramic PCB, which is the second type of the Ceramic Printed Circuit Board (PCB). The designation of this type is that it helps to mold the circuit board into a compact size.

5. Minimum Order Quantity

How many quantities or pieces can the Ceramic PCB manufacturer design within a specific time?

You should start looking at this from the perspective of the Minimum Order Quantity (MOQ). It is the limited or the few numbers of the Ceramic PCB that the manufacturer can accept.

6. Cost

While you are looking at the limited amount of Ceramic PCBs that the manufacturer can design, the cost should also be considered.

Ensure that the cost of the Ceramic PCB should fit into the budget you have made. At the same time, consider adding some money to your budget if the quality of the Ceramic PCB design is a bit higher than what you already budgeted.

7. Hybrid Integration

The Ceramic PCB shouldn’t be limited to one use cases and applications. The design of the circuit board should be something that can be integrated and used for many applications.

8. Number of Layers

The layers of the Ceramic PCB are another important factor you must consider when looking to choose a manufacturer.

There has been some confusion that has been commonplace on the number of layers that the Ceramic PCB should have. The number of layers is to be determined by the type of Ceramic Printed Circuit Board (PCB) you want to design because the use cases differ.

Despite that, the minimum number of layers that the Ceramic PCB should have is two. If the type you want to be designed has more advanced uses, the number of layers can also be increased.

Final Words

Ceramic substrate PCB has far better advantages and applications than what the traditional FR4 material PCB has to offer.

Having learned about the features and the reasons why it is better, we encourage you to use the guide above to select the best Ceramic PCB manufacturer.

What are the things you look for and consider before you outsource your Ceramic PCB project to a PCB manufacturer?

The evolution of technology has made it possible for Printed Circuit Boards (PCBs) to become versatile. And with most technological advancements, the innovations created the pathway for the advancement of PCB uses up to the point of integrating the boards in LED.

Background to LED Light

Lighting is important both in the home, in the street, and the industries. The continuous need for lighting led to the development of what has become one of the world’s best methods of lighting – the LED light.

The Light Emitting Diode (LED) emits high-quality light when the current flows through it. Hence, there may be little or no need for heat for creating light.

At the same time, there became a need to make LED lights versatile. That informs the reason for the various applications in the consumer and industrial sectors.

What Is LED PCB?

led pcb

LED PCB simply means the soldering of the Light Emitting Diode (LED) components with Printed Circuit Boards (PCBs).

The essence of adding PCBs is to improve shelf life and light quality. Therefore, it isn’t surprising that many PCB manufacturers are already integrating the boards into the LED.

How to Make SMD LED PCB

There are many types of Printed Circuit Boards (PCBs) that are used for designing LED lights.

Out of all those, the SMD LED is one of the most popular. With its fair share of upsides and downsides, it remains one of the best methods of integrating Printed Circuit Boards (PCBs) into LED lights.

When you are considering using the SMD LED PCB board, you must note some things. The first thing you should note is that the SMD is a set of small diodes that are used in the LED modules.

The simplified method of using SMD for LED is that it must be assembled on the Printed Circuit Board (PCB).

Also, making SMD LED on the Printed Circuit Board (PCB) makes it simpler to create a uniform and patterned source for the LED light. That is in addition to the enablement of the different luminaires to be added or integrated into the LED PCB.

How to Solder LED to PCB

The other important aspect of LED PCB is that the Light Emitting Diode (LED) must be soldered to the Printed Circuit Board (PCB).

Doing that requires precision and an eye for details so you don’t mix things up and face the adverse results.

Here are the steps to take or follow when you want to solder LED to a Printed Circuit Board (PCB):

Mount the LED Electrons

The first step is to mount the electrons of the Light Emitting Diode (LED). This is important because without doing that, it may be difficult to carry on with the other aspects of the LED PCB installation.

Solder the LED Electrons

Once the LED electrons have been mounted on the PCB, the next job would be to solder the same.

While some complain that the process may be hard, it can be as easy as anything. All there is to do here is to solder the LED electrons to the negative and the positive voltage terminals.

Installation of the Chip

It is then time to install the chip. It is this chip that ensures that the LED light is emitted.

The installation of the chip demands electrically connecting the said chip to the LED Printed Circuit Board (PCB).

Binding the Chip

The last step in the installation of the chip to the LED PCB is to bind it. Without this, it would be hard to keep it in place when the Printed Circuit Board (PCB) is finally completed.

When it comes to mounting the chip, two items will be used. The first is the Thermal Heat Sink. The second is the Ceramic Base. The two will be used alongside one another to bind the chip to the LED PCB.

How to Find the Right LED PCB Manufacturer

Are you looking for a LED PCB supplier or manufacturer? That is the first step to getting the right product. The second is to ensure that the supplier or manufacturer you want to patronize is the one that understands how to design the LED PCB.

To help you further, we have made a comprehensive guide that leads you by the hand with the strategic methods of finding out the best LED PCB manufacturer.

Here is the breakdown of the steps you must take to determine the right type of supplier or manufacturer you need for your next LED PCB project:

1. Cutting-Edge Technology

There is no denying that the success of every project depends partly on the expertise of the manufacturer/team and mainly because of the technology and machinery.

Therefore, your first concentration should be on the use of cutting-edge and latest technologies and machinery. A LED PCB manufacturer and supplier that has more of this tends to have better offers to make than another that doesn’t have.

2. LED PCB Consistency

Without sacrificing speed for quality, you must also ensure that the LED PCB supplier cum manufacturer can remain consistent on the job.

This is important because any slight deviation in the course of the job may alter the quality.

Besides, if you had already built a brand and name for yourself in the LED PCB industry, it may be hard to correct that mistake.

Therefore, ask for the supplier/manufacturer’s quality assurance to be sure that the quality of the LED PCB remains the same across different facets.

3. Specialization

You must understand that there are different aspects of the LED PCB. For example, the use cases span across different sectors, such as photography, LED torch, and automobile lights.

You must define the type of LED PCB that you want. And once you have an idea of the type or the application of the LED PCB, it becomes easier to select the best supplier.

As a rule of thumb, aim to outsource your LED PCB project to a supplier or manufacturer that specializes in one area. For example, if the job is about LED torch, a supplier that deals on LED torch and flashlights can handle it perfectly.

4. Industry Experience

Experience always counts in everything. It is the previous experience and expertise of a LED PCB supplier that determines if the next job will be successful.

When you have another LED PCB design or project at hand, always remember that it makes sense to prioritize a supplier that has many years of experience. It makes more sense if the supplier has versatile experience in both the private and public sectors of the LED PCB niche you want to hire them for.

5. Surety of Quality of Service

There may be no better way of determining the quality assurance of a LED PCB supplier other than finding out the certifications.

Those certifications are not only based on the years of experience of the supplier. They also reflect the potentiality of the LED PCB supplier to carry out the job using based on the industry standards.

The ISO9001 is one of the certifications you should look for to qualify the quality of service of a LED PCB manufacturer.

6. Light Control Technology

As much as many people are thrilled by the prospects of the Light Emitting Diode (LED), they don’t often have the right information.

The fact is that there are two ways to go about the installation or mounting of the LED on the PCB. The first is the Single LED that focuses on the emitting of high-quality light using only one LED light source. The other is the Whole Board LED that supplies high-quality light to the entire LED PCB.

It is for this reason that the use of Light Control Technology is the best. The impact of this technology is that it helps to bolster the performance of the Light Emitting Diode (LED) on the Printed Circuit Board (PCB).

Besides, Light Control Technology makes it possible for high-quality light to be effectively distributed across the entire board. That is in addition to the assurance of the interoperability of the LED light from the Single LED source to the Whole Board LED variant.

7. Heat Grooves

Excess heat isn’t needed on the LED PCB. It is because of the potential damages it can cause to the functions of the Light Emitting Diode (LED) PCB.

That is why you must place a premium on the heat grooves as one of the factors to consider when looking for the best LED PCB manufacturer.

The idea behind the heat grooves is that they help in the excellent dissipation and removal of excess heat from the LED PCB.

8. Speed of Production

Most times, it may be difficult to determine or find out if the LED PCB manufacturer/supplier can deliver the project on time.

Of course, many of the suppliers and manufacturers out there will claim to offer one of the fastest deliveries. But, once the project is handed to them, it will take ages to make the delivery.

The excellent way of determining the speed of production and delivery of the LED PCB is by checking the quoted delivery time after requesting a LED PCB.

At the same time, you may want to get in touch with some of the previous customers and clients of the LED PCB supplier you want to use. Their feedback in that regard will help you determine if the supplier’s speed of production is optimum or not.

9. V-Scoring

The importance of V-Scoring is that it helps in the scoring of the different components of the LED PCB.

Also, V-Scoring is important because it aids in facilitating the easy operation of the completed assembly of the LED PCB. It also plays a great role in the reduction of costs.

10. Pricing

The competitiveness of the prices is another crucial factor that must be considered anytime you want to select a LED PCB. This is because you may make all the evaluations only to end up discovering that the budget you set aside doesn’t fit into it.

On the one hand, you are considering the LED PCB manufacturer because of the competitive pricing offered.

On the other hand, you are looking to see if the quality of the LED PCB matches the price or cost of getting it done.

Above all, we advise that your major concentration should be on the quality of the project. That way, you will get the best even if it costs you extra money.

11. Minimum Order Quantity

The number of LED PCB orders you can place with Manufacturer A may not be the same as what you will get from Manufacturer B.

The Minimum Order Quantity (MOQ) gives you an idea of the lowest quantity or order that the LED PCB manufacturer/supplier can process.

Of course, you should always ensure that the minimum number of orders that the manufacturer can take is similar to what you have in mind. This is essential because the MOQ you will get may vary depending on the specifications of the company.

Why You Should Consider LED Lighting

Many reasons support why you must always endeavor to use LED PCB as the basis for the design of LED lights. More so, LED lighting has many obvious advantages and benefits over what the traditional lighting tends to offer.

Here are some of the benefits that you tend to derive from using LED PCB in your next LED lighting project:

Compact

The compact size or the simplified size of the LED PCB makes it ideal to be adapted and used in different applications.

That informs the reason why LED lighting is found in many of the electronics and other electrical appliances we use today. From cars to the LED torch and down to the traffic lights, the impact of the compact size of LED light is felt.

Reduced Energy Costs

You wouldn’t have to spend more money on your energy bills when you are using LED lighting. It is partly because of the lower energy use, and mainly because a few LED lights can brighten up space.

Heat Reduction

We don’t find it surprising that LED lights are considered “Calm” or “Cool” on the body. It is because it doesn’t use (more) heat as the traditional light bulbs do.

Besides, the heat reduction tenable on the LED light is 90% less than what the traditional light bulbs offer.

Conclusion

Finding the right LED PCB supplier and manufacturer is one of the easiest things you can do if you follow the tips we just shared. We are sure that those tips will help save you costs and time that you could have spent trying to figure out what makes the best LED PCB supplier.

What are the factors you consider before you decide to use the services of a LED PCB supplier or manufacturer?

Technology is all about making necessary advancements that will influence and bolster the success of different technological inputs. In the Printed Circuit Boards (PCBs) industry, it continues to play out with the introduction of the Rogers PCB.

In this context, we aim at helping you understand all there is to the Rogers PCB. You will also discover the benefits and the reasons why many PCB manufacturers will advise that you use it in your PCB designs. Finally, we will let you know the top 5 Rogers PCB manufacturers in China. That way, you wouldn’t look farther when you want to design your next Rogers PCB.

What Is Rogers PCB Material?

rogers 4350b pcb

We will start by saying that the essence of Rogers PCB is to reinvent and reposition the processes of manufacturing Printed Circuit Boards (PCBs). It is designed with the intent of performing better than the traditional FR-4 material.

Hence, the man idea behind the design of Rogers PCB is to provide better and more advanced features that will be used in the production of sturdy and long-lasting Printed Circuit Boards (PCBs).

About Rogers

Rogers is the company that manufactures Rogers PCB. The company centers its productions on the designing and manufacturing of laminate materials that will be used for the production of different types of Printed Circuit Boards (PCBs).

Besides, Rogers has one major goal, and that is to work on some of the inefficiencies of the traditional FR-4 material. By doing that, it hopes to chart the pathway for the all-around integration and use of its Rogers PCB in different PCB applications.

What Makes Rogers PCB Better Than the FR-4 Material?

We have continuously mentioned that the primary aim of the Rogers PCB is to make it easier for PCB manufacturers to make circuit boards. Of course, this is because of the advanced properties that the Rogers PCB has to offer.

So, what are those Rogers PCB properties that make it better than what we have had in the traditional FR-4 material?

1. Higher Frequencies

It is pertinent to mention that the traditional Flame Retardant Level 4 (FR-4) has limited frequencies. It is partly because of the copper foil lamination on both sides of the board, and mainly because of the epoxy composite/glass fiber components.

Instead of basing on the limited and lower frequencies that we have been seeing on the FR-4 material, the Rogers PCB offers a higher variant. This is because the manufacturer, Rogers will offer FR-4 core and additional copper laminate.

The advanced FR-4 core used here aids in the provision of higher frequencies, especially because of the inputs of PTFE (Teflon) reputed for the high frequency.

2. Wider Range of DK Values

In the comparison of the Rogers PCB and the FR-4 material, one of the most outstanding properties is the advanced DK values.

The Rogers PCB is famed for the wider range of DK values that it offers. That makes it better than the limited variant tenable in the FR-4 material.

Besides, the outstanding effects of the Rogers PCB are evident when it tested in line with impedance stability.

For example, the Dielectric Constant (DK) value of the Rogers PCB can be as high as 10.2.

3. Higher Costs; Higher Values

If there is any other reason why you mustn’t hesitate to use the Rogers PCB, it is the higher costs. Of course, it is understandable that you may be working on a budget. Hence, you may not have all the funds to spend on getting the PCB design done.

However, Rogers, the manufacturer of the Rogers PCB promises to offer higher quality with the board. And from what we have seen so far, the company is keeping to that promise by providing higher values in all ramifications to equate the higher costs of the Rogers PCB.

4. Less Variation

It is not out of place to check for the temperature management and sustenance of Printed Circuit Boards (PCBs). It helps to give insights into what must be done to ensure that the circuit board is operating in top shape at all times.

On the one hand, the FR-4 material has more variation when it comes to the temperature management of the circuit board.

5. Lower Signal Loss

It is rather sad for a circuit board to lose signals when it ought to have been working hard to get more. That has always been the case with the FR-4 material. That is also the basis for the use of the Rogers PCB to ensure that things go on as scheduled by having sufficient signals on the circuit board.

The major reason why the Rogers PCB does better in this regard is that it uses the lower Dissipation Factor (DF). It is the lower DF that makes it harder for the Rogers PCB to suffer from higher signal loss, as has been the case with the FR-4 material.

Features of the Rogers PCB Material

Before you look for where to buy Rogers PCB, we would like you to understand the features. Those properties will give you considerable insights into how the Rogers PCB towers higher than the other forms of laminate materials used in the designing and manufacturing of Printed Circuit Boards (PCBs).

Better Thermal Management

It is easier, cost-effective, and faster to manage the thermals of circuit boards if the Rogers PCB were used in the same.

That also implies improved efficiency and lower costs of managing the thermal points on a Printed Circuit Board (PCB).

Affordable PCB Fabrication

Fabricating Printed Circuit Boards (PCBs) may be costly because of some reasons, such as the manufacturer and the type of PCB that is to be manufactured.

However, the costs associated with the fabrication of Printed Circuit Boards (PCBs) will be significantly reduced when the Rogers PCB is used.

Higher and Wider DK Values

The values of the Dielectric Constant (DK) tend to be higher and wider when the Rogers PCB is the basis for designing the Printed Circuit Boards (PCBs).

For example, you can get or derive up to 10.2 Dielectric Constant (DK).

The other features and advantages of the Rogers PCB are:

  • Significant improvements in the impedance control
  • Reduction of the electrical loss on the PCB
  • Reduced and lower outgassing for space applications

Printed Circuit Boards (PCBs) are used in many electronics production because of the interconnection of electrical parts on the board. This is not leaving out the versatility of the boards that make them useful for different purposes.

The rigid flex PCB is one of the common types of Printed Circuit Boards (PCBs). We want you to understand what it is and how it works. That way, you will have in mind the expected outcomes of the PCB design before looking for the best rigid flex PCB manufacturer.

What Is a Rigid Flex PCB?

rigid-flex PCB

The rigid flex PCB is a hybrid circuit board design that integrates the rigid circuit substrates and the flexible circuit substrates. The combination of the two helps in the integration of the relevant elements from the flexible circuits and the hardboard.

Rigid Flex PCB Design

There are different types and designs that the rigid flex PCB can take. Out of all those options, only two seem to be outstanding as they have been repeatedly used over the years.

Here are the two major designs and types of the rigid flex PCB:

Dynamic Flex

This is the type that deals with the flexibility and long-standing effects of a printed circuit board even after repeated bending and folding.

Dynamic Flex also ensures that the traditional wear and tear associated with many PCBs aren’t common. With that in place, you are confident that the board will last for many years, even when used with some pressure.

Flex to Install

Extra care must be taken if you are looking at designing the Flex to Install variant of the rigid flex PCB. It is because of the limited options when it comes to folding and bending that makes this important.

For example, the major point of bending and folding the Flex to Install rigid flex PCB is when it is under assemblage. It is also possible for that to happen when the flex is being removed.

Therefore, additional bending and folding after this time may lead to wear and tear on the flex. So, try as much as possible to avoid using the Flex to Install rigid flex PCB in the high vibration use case.

The 10 Rigid Flex PCB Manufacturers You Can Trust

When it comes to designing a rigid flex PCB, you must be careful about the manufacturer you are hiring for the design.

The manufacturing phases of electronic appliances demand the input of Printed Circuit Boards (PCBs). These are the boards that help in connecting the relevant electrical parts of the electronics.

Now, the focus is on the varieties of PCBs out there. With the options readily available, electronics brands are always looking for the best. The heavy copper PCB happens to be one of the most used forms of the Printed Circuit Boards (PCBs).

You may have some heavy copper PCB questions too as those will help you understand how the board works. We have taken the time to create this content to capture the important aspects of the extreme copper PCB.

What Is Heavy Copper PCB?

heavy pcb copper

We would first like to point out that there is no concrete or specific definition of the heavy copper PCB. Rather, the use cases have tremendously helped in the comprehension of how it works.

The heavy copper PCB is the type of Printed Circuit Board (PCB) that has more thickness and components than the regular PCB does.

There are two variations in the definition of the heavy copper PCB. Below are those variations and how they work:

Sheet of Copper

The first component is the sheet of copper that the board has. Ideally, the traditional heavy copper PCB is the type that has up to 85 grams of copper or three ounces of copper.

This is usually located in the internal and external layers of the PCB.

Extreme Copper PCB

In some other cases, there are times when the PCB design will be advanced. That is the case that triggers the second variation – the extreme heavy copper.

The PCB copper thickness associated with this is up to 10 Oz for every ft2. When it comes to the inner and outer layers, the copper thickness or deposition is about 200 Oz for every ft2.

Heavy Copper PCB Features

You now know about the types of thicker and heavy PCB designs. Let us now look at the features and properties of such Printed Circuit Boards (PCBs).

Heavy Copper Plated Holes

The first feature is the number of copper holes. This is the case when more PCB plated holes are used to thicken the copper.

Reliable Wiring

Wiring and connecting the electrical components doesn’t prove difficult when using the heavy copper PCB design.

All there is to do is to combine the copper weight with an appropriate substrate. That is the reason why the thicker plating used in the through-hole circuit is very active.

Benefits of Heavy Copper PCB

We would like you to understand the benefits of the heavy copper PCB design before you look for a manufacturer to handle the job.

Do you have some things to gain when your next Printed Circuit Board (PCB) design is made of heavy copper?

Let’s find out!

1. More Loads

For many years now, electronics manufacturers have been wondering if there is a way to make their PCBs to handle more loads.

There is no more downplaying the importance of the heavy copper model of designing PCBs because it can handle more loads. It is because of the higher and efficient current carrying capacity that enables the more loads the PCB can handle.

1. Less Wiring Complications

The second benefit of PCB copper thickness is the less complicating wiring processes.

You wouldn’t have to bother about the fussy wiring that could have rendered the configuration distorting.

2. More Resistance and Endurance

The era of limited endurance of the Printed Circuit Board (PCB) is gone. This time, the more copper layer of the heavy PCB design ensures that the resistance and endurance levels are high.

Besides, the higher resistance is channeled in the area of using the copper-plated vias to provide more resistance to the high thermals.

On the other hand, the endurance of the heavy copper Printed Circuit Board (PCB) is measured in terms of the feasible use even in higher temperatures.

3. Improved Mechanical Features

The mechanical features and characteristics are another reason why the extreme copper PCB is gaining traction.

The importance of this model is that the exotic materials used in the design will dramatically improve the mechanical components of the PCB.

4. More Mechanical Power

You should also be expecting more mechanical power. This is partly because of the improvements in the connector sites and mainly because of the PTH holes.

5. Compact

As much as the heavy copper PCB design may be considered heavier, that isn’t always the case.

Instead, it has a compact and small size because of the integration of all the components into one PCB.

How to Select the Best Heavy Copper PCB Manufacturer

Your quest to have a heavy copper PCB can only be possible if you outsourced the job to a manufacturer that understands how to handle it.

We want the entire fabrication, design, and manufacturing process to be easy for you. That informs the reason why we made the guide below to help you find out the best manufacturer for the job:

1. Mass Production

The manufacturer that offers mass production should be among the first you must consider. There are many reasons why you should prioritize the same.

Here are the benefits of selecting a Printed Circuit Board manufacturing factory that offers mass production of PCBs:

Excellent Handling of Workloads

Because the manufacturer will have more loads to handle, you should ensure that the same can be completed in real-time.

The benefit thereof is that if the manufacturer can complete the job in a few weeks, it means you can rely on it. That way, when you have multiple heavy copper PCB orders, you already know who will handle it better.

The other benefit is that the more jobs are handled, the lower the costs you will pay. Ideally, the PCB manufacturer tends to give some discounts when you have many boards to be designed and manufactured.

2. Reputation

Reputation is the lifeblood of every business is a phrase we have come to understand in the business clime. It means that a company that has the trust and confidence of the customers tends to attract more customers.

As a client looking for the best heavy copper PCB manufacturer, you should consider this too.

Here are some of the ways you can confirm the reliability and reputation of the PCB manufacturer you want to use:

  • Visit the manufacturer’s social media profiles to see how it has been using content marketing. This is important as it shows that the manufacturer isn’t too particular to make money, but is also looking at helping the customers.
  • Visit the PCB manufacturer’s website to see the services offered. You may also check to see if there is an option to request a free quote.
  • Check for the previous customers’ reviews. Try balancing their reviews and responses to the manufacturer’s services to see if they are good or bad.
  • Take a survey to see the number of persons that will vote in favor of hiring the PCB manufacturer over the competing brands.

 

3. Turnaround Time

No matter how long you want the heavy copper PCB design to be delivered, you always wished it were early.

Therefore, focus your search for the best PCB manufacturer on the brand that can offer you faster delivery.

Besides, the design and pattern of the heavy copper PCB isn’t something that will take all the time in the world. Instead, the compact design ensures that all the necessary components and properties are assembled in a good time.

4. Availability of Tools

The PCB manufacturer you want to hire for your PCB manufacturing should have all the relevant tools and equipment required for making the project successful.

5. Replaceable Components

It is one thing to get in touch with the best heavy copper PCB factory or manufacturer. It is another thing to select the best manufacturer that can always provide the replacement parts of the PCB.

It is important to have this in mind because the PCB may develop some faults that will require the replacement of the parts. When you don’t have that on the ready, it may mean that the PCB wouldn’t be repaired.

6. Re-Installation and Repair Services

If the PCB factory can provide the replacement parts for the PCB, it should also fix the same.

You must consider and prioritize a PCB manufacturer that offers repair services for the Printed Circuit Boards (PCBs). The manufacturer should also offer re-installation services required for fixing the components after repairs.

7. Best Delivery Service

You should also check to see that the PCB manufacturer has the best delivery service. It is important to consider that because if the delivery service is excellent, it wouldn’t be long before the manufacturer will send the PCBs to you.

You also want to check the manufacturer’s website where you can see if the manufacturer has a dedicated delivery system. Also, check for the average delivery time that it will take the manufacturer to ship the PCBs to you once they are ready.

8. Certified Manufacturer

The other factor you must consider is the certification of the PCB manufacturer. It is pertinent to have this in mind because if the manufacturer doesn’t have the relevant certifications, it means that the quality of the PCB may be compromised.

One good reason why you should select a PCB manufacturer based on the certifications is because of the outcome of the job. Ideally, you are aiming to get the job done because of the manufacturer’s compliance with the laid-down rules and regulations in the industry.

9. Quality Check

While the experience and expertise of the PCB manufacturer count, the quality of the boards should count as well. It is important to check for the quality of the Printed Circuit Boards (PCBs) ahead of the design and manufacturing of the boards.

The best way to go about this is by checking through the manufacturing and testing procedures of the heavy copper PCB factory. That way, you will confirm the superiority and quality of the materials every time.

10. Be Specific About the Manufacturer You Want

There are many ways to calculate the features that make a PCB manufacturer the best out of its equals. Some of those are the type of PCB design services rendered and the entire procedures involved in the design.

First, you can select a printed circuit board manufacturing company based on the design only format. It means that the manufacturer will only design the heavy copper PCB and nothing more.

On the other hand, you may want to hire the services of a PCB manufacturer that can handle the entire process from start to finish. Some of the areas of consideration are the procurement of the PCB parts, the design, the assemblage, the fabrication, and the testing ahead of the delivery.

Why Would My Heavy Copper PCB Fail?

As much as the heavy copper printed circuit board is effective, it may have some challenges.

You must understand this at all times so it wouldn’t come as a surprise when the board develops some faults.

Here are some of the problems that may cause the heavy copper PCB to have some faults along the line:

Age

The longer the heavy copper PCB is in use, the more the chances of developing faults increases.

Therefore, you must always have in mind that the age of the PCB tends to have some roles to play in the failure of the board now or in the future.

Burnt Components

The PCB manufacturer may have made the mistake of using some burnt components to manufacture the board.

If that is the case, the failure or malfunctioning of the heavy copper PCB may be prominent after a while.

Low-Quality Materials

Sometimes, you may be working on a budget and have some few funds to spare. So, you should endeavor to use high-quality materials for your extreme copper PCB designs.

Final Words

The thickness of the printed circuit board (PCB) helps you to manufacture the best and quality PCBs.

That is why you must endeavor to use the services of an excellent and experienced PCB manufacturer that will help give the copper layer of the PCB the desired thickness for long-lasting effects.

Are you looking to select or hire the services of a PCB manufacturer that specializes in the use of aluminum to manufacture Printed Circuit Boards (PCBs)? You have come to the right place where the guide you will need will be given to you at no cost.

This content aims at providing in-depth information and guidelines on how you can determine or find out the manufacturer that does a great job on PCBs using aluminum.

What Does Aluminum PCB Mean?

Aluminum PCB

We want you to understand the underlying concept of the aluminum PCB. It is when you understand that it will become easier for you to learn about the benefits and advantages you will derive from using it.

Aluminum PCB is simply the use of metal substrate to manufacture printed circuit boards. It is roundly touted to be robust and efficient more than the standard PCB is.

The reasons for that are quite obvious. We will give you some instances of why aluminum core PCB is making waves all over the world.

History

You may be thinking that the use of substrate metal in manufacturing PCB has been on only a few years ago. On the contrary, aluminum PCB has been here for many decades.

The history dates back to the 70s when the first model was used. Also known as the Insulated Metal Substrate (IMS), this type of PCB was later to gain traction a few years after the first use.

Ideally, the adoptions began to grow after the use in the Amplification Hybrid Integrated Circuits. It was a few months after the use of the PCB made from substrate metal began to be used in many other applications and use cases.

Why the Preference for Aluminum PCB?

The postulations that the PCBs made under the aegis of aluminum are better are because of some reasons.

That is why we want you to understand the reasons and the factors why this is so. Also, you will now understand why the standard PCBs were relegated to the background after this type of PCBs began to dominate.

Environmental Friendliness

Because Printed Circuit Boards (PCBs) are used in electronics, it means the boards may be usable in many cases. At the same time, environmental factors tend to come in intervals to influence the efficiency or decline of the board.

Therefore, the first reason why aluminum undertones or metal substrate is used in the PCB board design is because of the environmental friendliness.

The ability of this type of PCB to withstand the higher risks when the environment becomes intense is the major reason why it is preferred.

Protection of the Components from Heat

Undue heat and dominance of heat can be a singular factor that will increase the reduced lifespan of a Printed Circuit Board (PCB).

For buyers that are looking at the long-term use and durability of the board, it makes sense to buy quality. And one way to buy quality is to ensure that the board is durable.

The aluminum PCB aids a great deal in that regard because of the higher protection it renders to the board against heat. It will interest you to know that the board can effectively disparate and expel undue heat when it is in use.

Power Regulation

Regulating power wouldn’t be a tough decision to make when you buy and use a Printed Circuit Board (PCB) that oozes quality. That is what you will derive from using the multi-layer metal core PCB.

The metal substrate therein is popular for the effective method that it bolsters the functions of the power converters in regulating current in the electronics.

Minimal Circuit Damage

Damages made to the circuit of the Printed Circuit Board (PCB) will be minimized when using aluminum PCB as the basis of the project.

How Can I Select the Best and Trusted Aluminum PCB Manufacturer?

Do you want to design aluminum PCB? Are you looking for a PCB manufacturer that can effectively handle the design?

Here are some of the effective tips on how to select a trusted manufacturer for your next aluminum PCB project.

1. Test Out the Project

Sometimes, you may be overly excited about having an aluminum PCB project done for you.

In that state of euphoria, you may not take the time to understand the important aspects of the job.

It is pertinent to have some background information and possibly checks on the board you want to be designed. The use of a third party will help you understand if the project will be worthwhile. Also, the opinion you garnered from the third party (usually another PCB manufacturer helps you to have an idea of the challenges and modifications that may be needed for the project’s success.

2. The Legitimacy of the Company

The other way of finding out the best aluminum PCB manufacturer is by checking for the company’s reputation and legitimacy.

There is no denying that many companies and brands out there will claim to offer the best service. You should take that with a pinch of salt, as every manufacturer will always claim to be the best.

What you should rather be looking at is the authenticity of the company. Check for the public records and the registration with the government or the relevant authorities.

Any PCB manufacturer that doesn’t have a record in the public domain nor registered with the relevant authorities may have some uncertainty hanging over it. That is why you must always check to see that the records are intact and up to date.

3. Schedule a Factory Visit

We must mention that visiting the factory or the PCB manufacturer’s business premises may not be the easiest thing to do but it is doable.

Most times, the manufacturer doesn’t allow such visits either because it has many projects to handle or because it cannot afford to sponsor the visit for some reason.

Whichever is the case, have it in mind that you may not have it easy to visit the manufacturer’s business premises. But, if it is something you are committed to doing, consider budgeting some money to last you for the trip.

And when you get to the factory, try as much as you can to see how things are done there. The insight will help you understand how the manufacturer carries out aluminum PCB designs. At the same time, it helps you to decide if the quality of service there is similar to what you expect.

4. Degree of Specialization

In the selection of aluminum PCB manufacturer, the quality of the project is always paramount.

It is pertinent to mention that the quality of the project may differ. For example, the quality of the aluminum PCB you get from a generalized PCB manufacturer may not be the same as the one you get from a specialized brand.

It is for this reason that we advise that you select the aluminum PCB manufacturer based on the degree of specialization. You can always determine this by the past projects the manufacturer handled and the reviews of the customers.

5. Qualitative Test

The quality of the aluminum PCB must also be tested, as that ensures you will be getting the best from the PCB.

Of course, it may cost you some money to request for preliminary testing for the aluminum PCB but it is worth it.

It is the outcome of the qualitative test that will help you understand the possible outcome of the final design of the Printed Circuit Board (PCB).

6. Quantity and On-Demand Design

Understandably, you may need some instantaneous design of the aluminum PCB. In such cases, you will want the PCB manufacturer to get the job done and fast too.

That informs the reason why you must select the PCB manufacturer based on the on-demand design of the aluminum PCB. Also, check for the possibility of getting a few quantities on request.

That way, you can always send out the requests for the aluminum PCB with hopes that the same will be delivered in real-time.

7. Technological Requirements

You should understand that the PCB board design doesn’t end at the components. Most times, the aluminum PCB manufacturer has to prove its mettle in offering the best service. And there may be no better way of doing that than by using the latest technological advancements and requirements.

Further, there are different types of PCB requirements. It makes sense that you understand these as they come in handy when selecting the best manufacturer.

The first technological requirement is the use of specialized scoring equipment. It must be mentioned that the essence of this equipment is there to give the needed scoring that helps to score the Printed Circuit Boards (PCBs) based on the performance.

The second technological requirement that the PCB manufacturer should have is the Hipot Test. This is the type of test that is used for the evaluation of the performance and overall quality of the aluminum PCB. Besides, the testing uses electrical methods, which is one of the fastest ways of confirming the quality of the board.

Another important technological requirement that the manufacturer must have is the image printer. There may be many options for that out there but the most common is the UV Light imaging equipment. It helps to facilitate the image printing on the aluminum PCB.

8. Learn from the Experience of Others

There may be no better way to uncover the expertise of aluminum PCB manufacturer than to learn from the previous customers.

Reviews continue to remain one of the strongest methods of finding out a PCB manufacturer that can be trusted with your project.

Therefore, do not hesitate to ask for or check the reviews of the previous customers that have patronized the manufacturer.

And if you have some courage and need for it, you may want to ask the PCB manufacturer to give you the references. The company will only be too willing to let you what others are thinking about the services it renders.

9. Attempt a Test Shipping

Try a test shipment to confirm how effective and excellent the shipping method of the PCB manufacture is.

Ideally, the shipment shouldn’t take more than 5 business days. And if it will, the company should take the cue of notifying you on time so you wouldn’t be left waiting.

10. Industry Standards

The design of the aluminum core PCB shouldn’t always go your way. Sometimes, the standards of the PCB industry must be held optimum when designing the board.

At the same time, try to acquaint yourself with the knowledge of the PCB industry standards. Check to see if the manufacturer understands that to so you wouldn’t have any problems with the outcome or quality of the aluminum PCB.

How to Use Aluminum to Make a PCB

So, how possible is it to manufacturer a Printed Circuit Board (PCB) using aluminum?

Here are the steps:

The Structure

The first thing you must understand is the structure of the aluminum PCB. This is usually four. The components are:

  • A dielectric layer
  • Aluminum base material
  • A layer of copper coil
  • Aluminum base layer

 

Metal Substrate

The most important aspect of the aluminum PCB design is the use of the metal substrate. This is commonly used when designing the base of the Printed Circuit Board (PCB).

How Aluminum Solder on Aluminum PCB Board

Do you want to know how to solder aluminum or the metal substrate on the PCB board?

Here are the simplified steps on how to do that:

Resin Filling

The resin used in the aluminum PCB is mostly based on the classification of the boards. For example, the polyimide or polyolefin resin is commonly used when designing the high-frequency aluminum PCB.

The other is the high thermal conductivity resin used in designing the high thermal-conductive aluminum PCB. In this instance, the epoxy resin is the most prominent as it is used in the dielectric layer of the board.

Solder Mask

As soon as the resin filling is achieved, the next step will be to apply the solder mask. The idea here is to use the solder mask printing on the aluminum PCB.

It must be mentioned that the two-time solder mask printing is commonly used because of the difficulty that tends to come up when using thick copper foil.

Final Words

Aluminum PCB simplifies the process of designing and manufacturing Printed Circuit Boards (PCBs). The other important thing to do is to check for the best aluminum PCB manufacturer that will make the job successful.

You can always leverage the tips we shared above to find the best manufacturer for your next aluminum PCB design.

You will find the Printed Circuit Board (PCB) in many electronics. The concept of using the PCB Board in balancing the electrical connection of electrical components is buoyed by the need to ensure that no wires are lying about.

Besides, the application of the PCB Board makes it possible to solder the electrical components into the board.

Worthy of mention is that the popularity of the PCB Board is not just because of the impressive inputs is makes in the electrical and electronic aspects of manufacturing. The board has since been adopted in many industries, such as in the aviation, electronics, and defence industries.

What Is a PCB Board?

pcb board

What is this PCB Board that has been making the news lately? What does it mean? How does it work? Are there any benefits that come with using the board?

First, the PCB Board is an abbreviation for the Printed Circuit Board (PCB). The PCB Board is a board that contains lines, pads, paths, and tracks. It is those elements as mentioned that are used to connect the various points or components of the board together.

Second, the PCB Board allows the soldering of the components onto the board with the aim of connecting the board to the mechanical and electronic components.

The third point to note is that the PCB Board creates a room for the passage of power and signals ahead of their routing between physical devices.

Fourth, the PCB Board is made up of substrate. It is atop this that the copper material will be laminated as a way of creating the needed connection route between the different components of the PCB Board.

Methods of Designing Printed Circuit Boards (PCBs)

Printed Circuit Board (PCB) has come a long way. It is the final outcome of a series of technological advancements aimed at bolstering the connection of electronic and electrical components in any appliance.

Contrary to the last invention (Wire Wrapping), the PCB Board happens to offer many other impressive upsides over the others. So, it is not out of place to posit that the Printed Circuit Board (PCB) stands a better chance in the market.

With that in mind, PCB has now taken different forms. Currently, there are two (2) ways to go about it. The first is called Through-Hole Technology. The second is called Surface Mount Technology (SMT).

We will explain each of those briefly.

  1. Through-Hole Technology

Through-Hole Technology is the first method of designing Printed Circuit Boards (PCBs).

It involved the mounting or placement of electronic components by leads. These leads will, on the one hand, be inserted through the holes on the side of the board. On the other hand, the leads will be soldered onto the copper traces on the other side of the board.

In as much as the Through-Hole Technology is now “obsolete,” it had a swell time when it was in vogue. It was because of the use of this method that PCB Boards manufactured at the time often had wires passing through the holes before getting soldered to the required components on the board.

  1. Surface Mount Technology

The Surface Mount Technology (SMT) is the second and the most advanced process of designing and manufacturing Printed Circuit Boards (PCBs).

In this case, the components or the required parts of the PCB Board are directly mounted on the surface of the Printed Circuit Board (PCB).

Worthy of mention is that the electronic devices made from the use of the Surface Mount Technology (SMT) are called the Surface Mount Devices (SMD).

The Surface Mount Technology is not only faster. It is also affordable and makes use of the latest PCB innovations.

Types of Printed Circuit Boards (PCBs)

It is no news that many people tend to confuse the PCB methods (as discussed above) with the PCB types.

We would like to point out here that they are different. On the other hand, the methods of PCB involve the two major processes involved or used in the designing and manufacturing of Printed Circuit Boards (PCBs). On the other hand, the types of Printed Circuit Boards (PCBs) have to do with the different variants which the PCB Board can come in.

So, we are going to look at the different types of Printed Circuit Boards. You will discover how each of them works, and what makes each of them different from the others.

  1. Single-Sided PCBs

As the name suggests, the Single-Sided PCB Board has only “one side.” Hence, it only has one layer of the base material, which is called the Substrate.

Single-Sided PCB Boards are ideal for people who are just starting out in the PCB industry. The non-complex circuitry makes it one of the fastest ways to master how to design and manufactures PCB Boards.

Metal is usually used to laminate one side of the base material of the Single-Sided PCB Board. The lamination helps to create a path for the building of electrical connection between the different electronic components that have or will be soldered on the board.

Protection of the board is done by placing a solder mask atop it.

When it comes to creating a conducting path, copper metal will be used. The choice is because of the fact that copper metal has low resistance and doubles as a good conductor.

Benefits of Using Single Sided PCBs

There are many benefits or upsides that come with using the Single Sided Printed Circuit Boards.

Some of the benefits are:

  • Easy availability, which creates a room for mass production
  • Doesn’t involve complex circuitry
  • Affordable
  • Can be used in many applications and use cases, such as printers, stereo components, power supplies, and calculators

 

  1. Double-Sided PCB Boards

You can easily guess that the Double Sided Printed Circuit Boards (PCBs) are the advanced form of the Single-Sided PCB Boards. They also tend to have two “two sides.”

That is not all there is to the Double Sided PCB Board. It will interest you to know that the board has an exception to the features of the Single-Sided PCB Boards. The exception is that it has copper materials on both sides of the substrate material.

Now, the components used on this board are connected using both the Through-Hole Technology and the Surface Mount Technology (SMT). The circuits positioned on one side of the board will also be connected to the ones on the side of the board. This will be done by making use of holes, which will be drilled on the board.

Benefits of Using Double-Sided PCB Boards

The Double-Sided PCB Boards have many amazing features, which will have you yearning to have one.

Here are some of the benefits of using the board:

  • Uses the two major technologies in PCB design and manufacturing
  • Has many advanced use cases, such as HVAC System, LED Lighting, Amplifiers, Vending Machines, and Automotive Dashboard.
  • The Double-Sided PCB Board has a moderate level of complexity, which makes it ideal for beginners, intermediates, and experts in the PCB industry.

 

  1. Multilayer PCB Boards

The Multilayer PCB Boards comprise both the properties of the Single-Sided PCB Board and those of the Double Sided PCB Board.

In this instance, the Multilayer PCB Boards make use of multiple layers. Also, the incorporation or addition of more layers is meant to serve as a preventive measure. The additional layers, among many other benefits, help to prevent the electromagnetic interferences, which are commonplace in this type of PCB Board design.

Besides, additional security measures are in place. This is clearly seen in the placement of a piece of insulation between each of the boards. This insulation helps in protecting the electronic and electrical components on the PCB Board from getting burnt when the heating process is ongoing.

Benefits of Using the Multilayer PCB Boards

What are the benefits or the advantages of using the Multilayer PCB Boards? Discover them below:

  • This type of PCB allows for the designing of complex and thick designs
  • The extra layers help to stop electromagnetic lapses in the course of the design
  • Multilayer PCB Boards are used in far advanced applications. The potential use cases are in analyzing weather, GPS Technology, and File Servers

 

How Are PCB Boards Made?

You want to know the processes involved in the designing and the manufacturing of PCB Boards. You are not alone on this.

We will summarize the processes of making Printed Circuit Board.

  1. Making the Substrate

The substrate will be made via many processes. The most outstanding of these procedures is the dipping in and spraying the substrate with epoxy resin.

It will later be rolled to get the desired thickness. The next step will be to get the needed solidity by placing it on the oven.

  1. Bonding the Copper Layers

The copper layers will be bonded on the surface of the substrate. This can be done in many ways, such as:

  • Applying adhesive and fixating the copper layers to the surface of the substrate
  • Applying pressure
  • Heating

After this, the other necessary components will be integrated, especially by using the soldering iron. Some of the components that can be incorporated here are:

  • LEDs
  • Capacitors
  • Transistors

 

  1. Solder Masking

There will be the final step of applying the solder mask. The solder mask performs man functions, such as protecting the metal parts and ensuring the smooth flow of currents to the relevant points in the PCB Board.

The PCB Board manufacturer will then remove the unnecessary parts and materials still stuck to the PCB Board.

You then have your PCB Board on your hands.

Wrapping Up

The use of PCB Board saves time, improves the efficiency of the electronic materials, and saves costs.

Always make sure you hire the services of a PCB Board manufacturer that understands the job, and who can follow your instructions to the letter.

Since Printed Circuit Boards (PCBs) came to beckon a standard in the manufacturing of electrical and electronic appliances, there has been some competition of sorts among the boards.

Ideally, there are different types of PCBs, which makes it competitive as one board type tries to hold the upper hand over the others. Besides, the trio of the Single-Sided PCB, the Double-Sided PCB, and the Multilayer PCB are commonly used.

The 4 Layer PCB

4layer pcb

Now, the 4 Layer PCB, which happens to fall under the Multilayer PCB, has been in the spotlight for some time. This is in consideration of the fact that it has some amazing properties that have been causing PCB customers and buyers to think of getting one of it.

In this article, we shall take you on a tour of the important things you need to know about the 4 Layer PCB. You will discover why it has the upper hand instead of its competitor – the 2 Layer PCB.

Besides, the massive use of the 4 Layer PCB and the various use cases combine to make it one of the Printed Circuit Boards (PCBs) that cannot be ignored.

Is 4 Layer PCB Complex?

The designing and the manufacturing of Printed Circuit Boards (PCBs) doesn’t come easy. You will have to be patient throughout the process. You will also need to pay attention to the procedure so you don’t miss anything.

Also, you have to understand the complexity of the Printed Circuit Boards (PCBs) tend to vary by the types. The complexity or difficulty experienced with the designing and the manufacturing of the Single-Sided PCB is not the same as the 4 Layer PCB. It is because the complex nature of the 4 Layer PCB is higher than the others are.

So, the 4 Layer PCB is quite complex because it falls under the category of the Multilayer PCBs.

We will also like to point out that the Multilayer Printed Circuit Boards (PCBs) are not limited to the 4 Layer PCB alone. Instead, they can go as high as eight layers. In the light of that, every other increment in the layers attracts the addition or integration of two more layers to the board.

Dissecting the 4 Layer PCB

The components of the 4 Layer PCB must be dissected. Here, we will look at the different layers that make up the 4 Layer PCB.

  • Top Layer

The four (4) layers that make up the 4 Layer PCB are divided into three categories. The Top Layer is the first category.

As the name suggests, the Top Layer is placed at the top part or section of the board. The Top Layer is also part of the outer layers (including the Bottom Layers). These outer layers form the sections for the placement of components and routing.

Aside from the Top Layer, there are other important layers, which are placed beneath it. These are not part of the other layers that make it four (4).

The first layer, in this case, is the Signal Layer, which has a width of about 0.0014 inches.

The second layer that comes after it is the Preg Layer. It has a dielectric constant of 4.2 and a thickness of about 0.0091 inches.

Generally, the components of the Top Layer are made of copper material. After the Top Layer, there are two other layers, which will be discussed below.

  • The Core Layer

The next layer is the Core Layer. It is called the Core Layer because it has most of the important components that power the Printed Circuit Board (PCB).

The Core Layer in this instance refers to the Inner Layer 1 and the Inner Layer 2. These layers (Inner Layer 1 and Inner Layer 2) are often used for signal routing and as power planes.

To break them down further, we will look at the individual parts or components of each of the aforementioned layers.

On the one hand, there is Inner Layer 1. Here, there is the Pre-Preg Layer, which is generally called the Plane. It is closely followed by the Inner Layer 1 of 0.0014 inches. There is also the Core Sublayer, which is a part of the Inner Layer 1. The Core Sublayer has a width of about 0.0037 inches.

On the other hand, there is the Inner Layer 2, which forms part of the Core Layers for the 4 Layer PCB. It has a Plane Layer that comprises a thickness of 0.0014 inches. The Plane Layer also has 1 oz. of copper. The Inner Layer 2 also has a Pre-Preg Layer that has two sheets of thickness 0.0091 inches.

  • Bottom Layer

The Bottom Layer is the last layer or part of the 4 Layer PCB. It also doubles as a Signal Layer (just like the Top Layer is) and has a thickness of 0.0014 inches.

 

How to Design the 4 Layer PCB Stack Up

If you are looking at how to design the stack up for the 4 Layer PCB, we got you covered.

We are presenting you with three options.

Option 1:

Under this option, the idea is to design the stack up using one layer of power supply, two signal layers, and one ground layer.

Here are itemized steps to achieve that:

  • The Top Layer (the Power Layer) comes first
  • The Signal Layer (Layer 2) comes next
  • Layer 3 (the Signal Layer too) follows
  • The Ground Layer (the Bottom Layer) comes last

This design aims to achieve a specific shielding effect by placing the power and the ground layers at the top and the bottom layers of the 4 Layer PCB, respectively.

Option 2:

If you don’t want to use the first option (as discussed above), you want to use the second option instead.

The second option we have here is designed to decouple the effect of the power plane/layer. It can also contribute to the reduction of the distributed impedance of the ground layer and the top layer, only if the impedance control board is not too thick.

Here is how to design the stack-up of the 4 Layer PCB using the second option we just discussed:

  • The Top (Signal Layer) comes first
  • The Ground Layer (Layer 2) comes next
  • The Power Layer (Layer 3) follows
  • The Signal Layer (the Bottom Layer) is the last

 

Option 3:

There is the third and last option you can leverage to design the stack-up of the 4 Layer PCB.

This option is usually used when there is a need to wire the underlying signal layer or the bottom layer.

Here is how to design the 4 Layer PCB stack up using the third option:

  • The Signal Layer (the Top Layer) comes first
  • The Power Layer (Layer 2) follows
  • The Ground Layer (Layer 3) comes under Layer 2
  • The Signal Layer (the Bottom Layer) will be the last

 

Important Aspects of the 4 Layer PCB

The 4 Layer PCB has specific features that set it apart from the other Printed Circuit Boards (PCBs).

Here are some of them:

  1. Altering the Layers

The layers of the 4 Layer PCB can be altered without any glitches. This makes it better than the other types of PCBs, which may develop some issues when the layers are altered.

The focus is on the altering of the layers, which are connected by vias. The vias, which are plated holes that pass through the substrate to connect different layers of the copper, plays an important role in the 4 Layer PCB.

The vias of the 4 Layer PCB can be altered in many ways. Some of them are:

  • Burying the vias in the PCB in a way that it still connects the internal layers while “out of sight.”
  • There is also the option to run the vias as “through vias,” meaning that it can connect all the layers.
  • The vias can also be used in a “blind vias” format whereby it runs to some length and stops the connection at a specific point in the Printed Circuit Board.

 

  1. More Surface Area Tracing

More surface areas can be traced in the 4 Layer PCB. This is bolstered by the use of the Pre-Preg layer that provides dielectric between the layers.

It is also because of the application of heat and pressure using the Pre-Preg layer. This, in turn, helps to bond the Single-Sided PCBs and the Multilayer PCBs.

  1. Higher Sensitivity

The 4 Layer PCB has a higher sensitivity more than the other types of Printed Circuit Boards (PCBs). It also reduces propagation levels, uses a complex design, and reduces distortion.

Final Thoughts

When you are looking at making use of the 4 Layer PCB for your next Printed Circuit Boards (PCBs), make sure you have understood the things that are involved.

Above all, ensure that you contact a reliable PCB manufacturer that offers instant quotes, the best materials, and affordable pricing.

So, what do you think of the 4 Layer PCB?

2 layer PCB

When it comes to the designing and the manufacturing of the Printed Circuit Boards (PCBs), the 2 Layer PCB is one of the options you can use.

The 2 Layer PCB is a type of Printed Circuit Boards (PCBs) that provides flexible accommodation of electrical components on the board. The 2 Layer PCB also helps to keep the board organized by striking the needed connection directly from the top layer to the bottom layer. It also provides enough space for the conductor patterns.

What Is the 2 Layer PCB?

The 2 Layer PCB is a type of Printed Circuit Board (PCB) that has only two layers. We would also like to mention that although the 2 Layer PCB has more layers than the Single-Sided PCB (One Layer PCB), it doesn’t have more layers than the Multilayer PCB, which is where the 4 Layer PCB and the others fall into.

Second, the mass of the 2 Layer PCB makes it easier to have more layouts and surface for traces. Hence, the things that may not have been achieved in the Single-Sided PCB for want of space can be accomplished when using the 2 Layer PCB.

Third, the 2 Layer PCB provides more surface areas, which are ideal for housing the conductor pattern.

The fourth and most important point is that the 2 Layer PCB can be used in terms of mounting conductive copper and components on both sides of the PCB being worked on. The importance of this is that traces can cross over each other.

Stack Up of the 2 Layer PCB

The 2 Layer PCB has a simplified stack up. This stack-up does not only make the task of layering it easier. It also helps to facilitate the completion of the design in good time.

So, what is the “special” stack up process that is being used on the 2 Layer PCB?

2 Layer PCB uses a Dual-Stack Up. This means that it only makes use of the primary components or layers, which are the Top Layer and the Bottom Layer.

Do I Need to Use a Ground Plane on Your 2 Layer PCB?

There are some consistent questions, which are being asked about the possibility of using Ground Planes on the 2 Layer PCB. Is it advised to use it?

We have looked at the potentiality of using the Ground Plane in your 2 Layer PCB, and came up with the submissions below:

  • The Space Determines

Space or “real estate” you have available on your 2 Layer PCB should determine if you will integrate the Ground Plane.

Because there tends to be limited space on the 2 Layer PCB following the non-routing of signals through the internal signal layers, you may not have enough space left.

In this case, it is advised that you look for some space (if any) where the Ground Plane can be placed on the Printed Circuit Board (PCB).

Have in mind that if you are to mount or place the Ground Plane on your 2 Layer PCB, it has to be on one layer alone. So, you have to decide whether to place it on the Top Layer or the Bottom Layer.

Going by the name, it may ideal to place the Ground Plane on the Bottom Layer of your 2 Layer PCB.

  • The Ground Plane Prevents Radiation

If you were successful at finding a space on the PCB for the Ground Plane, the next step is to start using it.

Ideally, one of the major advantages of having the Ground Plane on your 2 Layer PCB is that it helps to prevent radiation. It does this by providing some level of protection that tends to come from the EMI radiations.

  • Placing the Ground Plane Close to Signal Traces

You can also take the placement of the Ground Plane to another level. This time, you are looking at placing it close to the signal traces.

If you do that, you can be sure that there will be limited EMI susceptibility and minimal inductances in the loop. This is bolstered by the fact that the return signals will have to closely follow the traces.

  • Gridding

If you are not familiar with or you don’t want to use the placement of the Ground Plane to the Bottom Layer, you can use another option. This option is called “Gridding.”

It simply means that the Power and the Ground Traces can be routed in a way that they will not be interfering with each other’s operations.

Considering that this can give way to increase in noise, you have to do something about it. One of the things you can do here is to fill the empty spaces with Ground Pour.

How Does the 2 Layer PCB Work?

There isn’t much to the 2 Layer PCB. It only needs to be placed in the right way to work accurately.

We must also mention that the 2 Layer PCB can function better if it is used alongside the microstrip traces and the ground planes.

If those are in place, the functionality of the 2 Layer PCB will be higher because there are little or no propagation delays to prevent it from working accurately.

The Design of the 2 Layer PCB

The 2 Layer PCB has a definite design. There are two angles to its design, and those have been discussed below.

  • Vias’ Use

As you may have known, Printed Circuit Boards (PCBs) make use of vias for connectivity. This also becomes one of the strongest points of the 2 Layer PCB.

Here, the vias are primarily used to create the needed electrical connections. It is those connections that would, in turn, be used to route the traces until they get to the other side of the board.

  • More Surface Area

The 2 Layer PCB is two times larger than the 2 Layer PCB. That means it has more spaces for additional components to be added.

To that end, the more surface area that is there provides just enough space for the inclusion of a conductor pattern.

2 Layer PCB vs. 4 Layer PCB

As earlier mentioned, the 2 Layer PCB is only one out of the many types of Printed Circuit Boards (PCBs). It comes after the Single-Sided PCBs, and after it, there is the Multilayer PCBs.

Most times, the 2 Layer PCB has been compared to the 4 Layer PCB, which happens to fall under the category of the Multilayer PCBs. The comparison is quite understandable considering that both types of PCBs (the 2 Layer PCB and the 4 Layer PCBs) have something in common.

From the use of the top and the bottom layers to the medium of connections, the 2 Layer PCB and the 4 Layer PCB are often compared.

Despite the comparison, some factors still come into play to distinguish the 2 Layer PCB from the 4 Layer PCB.

How to Choose Your 2 Layer PCB

So, you are intent on designing your first 2 Layer PCB. That is a commendable move.

However, we want you to know some things before you proceed. These factors will help you in making a decision on how to select or choose your next 2 Layer PCB.

Here are the things you need to put into consideration:

  • Lead Time

The Lead Time is similar to “how fast” the 2 Layer PCB can be designed. It might interest you to know that 2 Layer PCBs have one of the fastest Lead Times. Ideally, the board can be shipped within 24 hours (1 day) from the time of receipt.

  • Level of Functionality

The 2 Layer PCB is between simplicity and complexity. If you can perfectly design One Layer (Single-Sided PCB), you may not have some trouble with the 2 Layer PCB.

Nonetheless, you may enlist the services of a PCB manufacturer to help you with the project.

Aside from that, you have to consider the functionality of the 2 Layer PCB. If it is more complex, you may have to start considering using the 4 Layer PCB.

  • Budget/Cost

The cost has always been an influential factor in the selection of 2 Layer PCB. For good reasons, you can leverage this.

This is because the 2 Layer PCB doesn’t dip many holes in your pocket the way the 4 Layer PCB does.

Therefore, if you are looking at getting your Printed Circuit Board (PCB) done without breaking the bank, the 2 Layer PCB is your sure bet.

  • Dimension/Size

What is the size or the maximum dimension you expect of your Printed Circuit Board (PCB)?

Ideally, the 2 Layer PCB has a maximum board size/dimension of 650x520mm. So, if your expectation is above that, you want to consider the 4 Layer PCB with a maximum dimension of 650x500mm.

Wrapping Up

The 2 Layer PCB proves to be one of the cost-effective, flexible, spacious (than the Single-Sided PCB), and a PCB with one of the fastest lead time.

You want to make use of a PCB manufacturer that has many years of experience working at the 2 Layer PCB because that is a guarantee that your project is in safe hands.

A lot of work goes into the fabrication and the assembly of Printed Circuit Boards (PCBs). For people who may not be conversant with how the two processes work, we have put together some helpful tips to help you in understanding how each of these important PCB techniques works.

PCB Fab and Assembly

What Is PCB Fabrication?

It is important to explain each of these PCB processes so that you will understand how they work. The first is the PCB Fab.

What is PCB Fab? PCB Fab, which is the short form of Printed Circuit Board (PCB) Fabrication, is a specific method of assembling the components and the properties of a Printed Circuit Board (PCB).

This assembly is specifically for the manufacturing of PCBs, which are mainly used in computer and electronic devices.

Ideally, the layers of the Printed Circuit Boards (PCBs) will be put together alongside the surface pattern. This will later be used in the manufacturing of electronics.

Important Steps in PCB Fabrication

The fabrication of Printed Circuit Boards (PCBs) doesn’t come easy. Many processes and steps have to be taken before you can successfully get it done.

We understand the importance of mastering these processes, as they are beneficial when you want to produce reliable Printed Circuit Boards (PCBs).

Read on to find out the various steps in this ultimate guide to PCB Fabrication.

  1. PCB Layout

The design or the layout of the Printed Circuit Boards (PCBs) should be paramount. It is only when you have a general outlook (layout) of the boards that you can be able to proceed with the fabrication.

In this case, you are looking at connecting the different elements, as well as widening the routes, and placing vias on the different sizes that they match.

There are more things to the fabrication of Printed Circuit Boards (PCBs). We have explained those below.

  • Software Selection

The software plays an important role in the outcome of the PCB design. With many software versions out there, you may not be sure of the one to use.

We advise that you stick to the primary software that is common in the PCB industry. These are the Eagle, Altium Designer, KiCad, OrCAD, and Pads.

  • Gerber Files

Many PCB manufacturers allow you to upload your Gerber Files. These files are the expected outcomes you want to have at the end of the PCB fabrication and assembly. With that in mind, the PCB manufacturer will set about the task of working to meet up with your expectations.

Having said that, we also need to consider other important aspects of the Gerber Files. The Gerber files have specific information and requirements that must be met.

This ranges from the Component Notations, the Copper Tracking Layers, the Apertures, and the Drill Drawing.

Aside from those, here are the other necessary files that need to be in place before a Printed Circuit Board (PCB) can be manufactured.

  • Paste layers
  • Solder mask
  • One or more fabrication drawings
  • An accurate outline that shows the slots and cutouts on the PCBs
  • A drill file (with the Excellon format ASCII) should be used for each cycle.
  • Tool codes for the drill files

 

  • Review

 

The Gerber files and other related documents will be sent to the PCB manufacturer through the dedicated channel. It could be posting it to the manufacturer’s office or uploading the Gerber files on the PCB manufacturer’s website.

Once the manufacturer acknowledges receipt of the Gerber files, the next step would be to submit the same to the engineer for review.

This pre-production engineering process helps in the discovery of likely missing documents and helps in running the necessary checks. The accurate quotation will also be given during this process.

At the end of it all, the quotation will be released and if you are okay with it, the production phase will be initiated.

PCB Fab and Assembly

  1. Pre-Production

Before the actual production of the PCB, some steps need to be taken.

First, cutting and lamination will be done. This will be centred on the size of the panel or the size of the finished board.

Second, the board will be dried. The aim is to prevent the board from warping during the production phase. It also helps to remove the moisture on the Printed Circuit Board (PCB).

Ideally, the drying process will be done for 4 hours at a temperature of 150 degrees centigrade.

 

  1. Inner Layer Imaging

The inner layer of the Printed Circuit Board (PCB) will pass through the imaging phase.

Here, a dry film (Inner Film) will be applied to the visible copper core board. Also, the necessary photo imaged reactions will be carried out on the dry film.

The next step is the Inner Exposure, where the core plate will be allowed to dry.

The third step here is to develop the inner layer (Inner Layer Development). In this case, the unexposed dry film will be developed to the point that the original copper skin is revealed. The exposed dry film will also be retained. On the other hand, the exposed core plate of the PCB will be developed too.

 

  1. Etching the Inner Layer

The inner layer of the Printed Circuit Board (PCB) will also be etched. In the course of etching the line, there will be a protection of the copper skin that is covered by the dry film.

On the other hand, the copper skin, which has not been protected by the dry film, will be etched away.

Besides, if there is a need to retain any of the line patterns, such would be retained after it must have been displayed by the etching process.

If the line pattern must be fully retained, the dry film of the copper sheet on the main board must be treated.

 

  1. Automatic Optical Inspection

Here, the Automatic Optical Inspection (AOI) will be carried out on the inner layer of the Printed Circuit Board (PCB).

The aim of running the Automatic Optical Inspection (AOI) is to check the reliability of the etching. Here, the concentration is on finding out if the etching was clean or not. It also checks if the core plate of the PCB has an open or a short circuit after etching.

 

  1. Lamination

The lamination process has to do with the pressing of one board via the insulating medium called the “PP.”

  1. Drilling

The drilling process entails laminating the plate of the PCB. Because there is no metal on the hole of the board, the layers may not be connected.

  1. Hole Coating

A hole will be coated on the Printed Circuit Board (PCB) via a process called “Electroless Copper Deposition.”

This will be done via a chemical reaction and will require about 3um of very thin layered copper.

  1. Hole Thickening

The hole on the PCB will be thickened to 8um using the electron transfer reaction. It is important to mention that this will be actualized by using horizontal electrolytic plating on the copper in the hole and on the copper in the bare plate.

  1. Imaging the Outer Layer

The outer layer of the PCB will be imaged. Among the many processes involved here is the performing of photo imaged reactions on the dry film, the drilling of holes on the plate, as well as the application of the dry film to protect the hole on the plate.

The outer layer will also be exposed and later developed by etching the copper on the dry film.

  1. Graphic Plating

The copper that needs to be retained at the end/the bare copper will be thickened through the thick copper plating and the tin plating processes.

  1. Etching the Outer Layer

The outer layer of the copper will be etched by retaining the copper protecting the tin.

Also, the tin protecting the copper will be removed.

  1. Masking and Silkscreen

The entire panel of the PCB will be coated with the solder mask. After it must have been exposed to high-density UV light, the panel will not be susceptible to corrosion and oxidation.

The Silkscreen process will then come next. Here, the important information of the Printed Circuit Board (PCB) will be printed on it.

  1. Surface Finish

The Printed Circuit Board (PCB) will finally be passed onto the surface finishing and the coating processes.

The idea here is that the PCB will have better soldering and will have the surface protected.

  1. Profiling and Testing

The Printed Circuit Board (PCB) will be checked thoroughly for possible corrections. If none was found, it will be tested electrically to ensure that the board functions as expected.

  1. Final Inspection

There will be a Final Visual Inspection, where the quality control experts will inspect the PCB.

Some of the areas of inspection are:

  • Warpage requirement
  • Visual inspection
  • Aperture hole number measurement
  • Product size inspection

If the PCB scaled or passed the inspection, it will be designed a test report that shows the outcome of the inspection.

Wrapping Up

Once the Printed Circuit Board (PCB) has been confirmed to comply with the industry standards (and after it must have passed the tests), it will be packaged and delivered to the buyers.

We believe that you have now understood the basic processes involved in PCB Fabrication and Assembly.
