Top 4 CEM-1 PCB Manufacturers

Composite Epoxy Materials 1 (CEM-1) is still popular in the Printed Circuit Board (PCB) industry. Despite the proliferation of other types of PCB materials, CEM-1 is undoubtedly one of the best materials you can use to design your circuit boards.

Several manufacturers still use this type of PCB material to produce circuit boards and we are sure you want to hire their services. That informs the reason why we put together this article to help you understand everything about CEM-1 as a PCB material, as well as the manufacturers that will design the board for you.


What Is CEM-1 PCB Material?

Cem PCB Material

The first thing you need to understand is the meaning of CEM-1 in the circuit board manufacturing process.

First, we need to understand the general overview of Composite Epoxy Material (CEM), which is the major material that is considered.

Composite Epoxy Material (CEM) is a group of composite materials that are typically produced from woven glass fabric surfaces. Also, the production of the materials includes the combination of a non-woven glass core with epoxy synthetic resin.

On the other hand, CEM-1 is a composite material that is placed on a cellulose basis whereby the only layer of the material (usually a glass fiber laminate, FR-4) is placed on the surface.

CEM-1 materials are also common in Printed Circuit Boards (PCBs) that use paper cellulose, and two layers of woven glass fabric. Those are then mixed with epoxy, which serves as the substrate material.

Identifying CEM-1 PCB materials is easy because the materials have distinct colors, which are milky yellow or milky white.

Why Do PCB Consumers Like CEM-1 PCBs?

Are you wondering why Composite Epoxy Material Grade 1 (CEM-1) is still popular and used in the Printed Circuit Board (PCB) industry up to today? You are not the only one that is surprised, because it is assumed that the material must have been discarded long ago.

CEM-1 is still a standard material for the production of Printed Circuit Boards (PCBs) because of the many advantages it has. Here are some of them:

1. CEM-1 Supports Multiple PCB Components

The first advantage of this type of PCB material is the stability that creates room for the support of multiple PCB components.

Because of the sturdiness of the board, manufacturers wouldn’t find it difficult to mount the necessary components needed for the production of CEM-1 PCBs.

2. CEM-1 Excellently Supports Single-Layer Circuit Boards

Single-layer circuit board production is now simpler because of the excellent support provided by the material towards the production of single layers that are lighter in weight.

3. Manufacturing Bulk Products is Now Easier

You can now manufacture products in bulk provided you are using the CEM-1 material that enables that.

The idea here is to help you produce multiple products without compromising on their quality or spending more money than you budgeted. Some of the bulk products that can be manufactured using CEM-1 include, but are not limited to:


4. Energy Storage is Better Managed

Heat dissipation is one problem that can have adverse effects on a circuit board like CEM-1. So, it makes sense that there is a better way to manage energy, as well as the transfer of (excess) heat from the circuit board.

First, circuit boards manufactured with CEM-1 materials have a cab store for electric energy.

Second, the circuit board has a good glass transition temperature that provides a good balance between heat-dissipating performance and the manufacturing process of LED lighting.

5. CEM-1 Materials Reduce the Cost of Manufacturing Circuit Boards

Have you spent a fortune in the past manufacturing Printed Circuit Boards (PCBs)? You wouldn’t spend that much again because CEM-1 materials help to reduce the costs of manufacturing circuit boards.

That is achieved by the coating of only one side of the circuit board with copper. Also, the coating doesn’t in any way reduce the efficiency of the circuit board because it still has good conducting characteristics.

6. CEM-1 PCBs Compete with FR-4 Materials

Flame Retardant Level 4 (FR-4) materials have been in use for many years, and that is because of the excellent properties they have.

As much as FR-4 materials are still in use, it appears that CEM-1 9 (which was assumed to be in relegation) is a fierce competitor to the FR-4 materials.

That is because CEM-1 circuit boards can conveniently attain/achieve the same level of electrical and mechanical properties as the FR-4 materials do.

Therefore, it is safe to posit that Composite Epoxy Material Grade 1 (CEM-1) can be used in place of the Flame Retardant Level 4 (FR-4) in some cases.

When Can CEM-1 PCBs Be Used?

So, what are some of the applications or products that CEM-1 circuit boards can be used? Here are some of them:

1. Computers

The major reason why computers are part of the applications or products that use CEM-1 circuit boards is that the board conveniently reduces heat. And because computers emit more energy and are sensitive to heat, it makes sense that their circuit boards are made of CEM-1 materials.

Some of the computer components that are manufactured with CEM-1 Printed Circuit Boards (PCBs) include:

  • Computer power devices
  • Central Processing Units (CPUs) and
  • Floppy drives


2. CEM-1 PCBs are Used in the Production of LED Lighting

LED lighting products are also manufactured using CEM-1 circuit boards. Some of them include:

  • Break lights
  • Headlights and
  • Indicators


3. Surgical Equipment

Tools used for surgeries are also manufactured with CEM-1 circuit boards. Medical scanning technology is also a part of the tools manufactured with the CEM-1 LED circuit board.


The use cases of Composite Epoxy Material Grade 1 (CEM-1) are many. That shows that the materials therein are useful, and can make circuit boards better.
