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
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.
