Everything About Why The Cem-1 Back Is Necessary?

Printed circuit boards are widely preferred in different products like communications, effects of information technology, automobiles, consumer electronics, semiconductors, etc. They differ based on the requirements of other products like different substrates, outermost solder protection, interlayer, and soldered connection materials. CEM-1 back supplier considers that in PBCs, they serve a primary function based on the materials used.

They are divided into different products such as Flexible PCB, Rigid PCB, Rigid-Flexible Composite PCB, and IC boards. Composite Epoxy Copper Clad Laminate (CEM-1) comprises two substrates, and core material uses bleached kraft paper, and fabric uses fiberglass cloth. The Single-sided Copper Clad Laminate is the main product. They are providing PCBs compact sizes and high-density circuit layouts.

What Makes CEM 1 Highly Preferred?

The CEM copper laminate is compatible and highly versatile. They have a higher transition temperature than FR-4 and the lead-free reflow technology as it features. Moreover, it has superior flexural strength, like the dielectric’s ability to manage physical stress without breaking. Also, CEM-1 back supplier is non-toxic, halogen-free, and doesn’t contain phosphorus antimony. Also, it comprises of good dimension stability.

Different manufacturing ranges are there in CEM1 like Aluminum Clad sheets, Copper Clad Panels, and Copper Clad Laminates. Moreover, they have incredible features because they demand the market like highly efficient, optimum strength, highly durable, and easy usability.

Benefits of CEM 1

  • Auto V-cut and directing lines
  • Programmed UV light set solder mask and silkscreen quick
  • Suitable scratching and washing measures with the proper synthetic substances for a single CEM PCB
  • Unique single layer creation line

Types of Composite Epoxy Copper Clad Laminate

1. ETL-CEM1-502

These CEMs have high-flame resistance of composite epoxy laminate. Also, they contain a high anti-tracking with excellent dimensional stability and also have white substrate. As they are highly versatile, they are preferred for numerous applications like

  • Power drive board
  • Suitable for silver/copper paste through hole
  • Suitable for SMT process
  • Suitable for HASL process

2. ETL-CEM1-502(F TYPE)

These ETL-CEM1-502(F TYPE) are also flame resistant and are composite epoxy laminate. They are similar to the ETL-CEM1-502 as they have a high anti-tracking and excellent dimensional stability. The only difference between the two types of CEM-1 is that it forms a yellow substrate. It has a few application like:

  • Power drive board
  • General Usage

3. ETL-CEM1-502(FW TYPE)

The third type is ETL-CEM1-502(FW TYPE), which is flame resistant and is a composite epoxy laminate with high anti-tracking and perfect dimensional stability. However, form a white substrate with a diverse range of application like

  • Power drive board
  • General Usage

4. ETL-CEM1-502(Y TYPE)

The last type is ETL-CEM1-502(Y TYPE), which have similar properties to the others mentioned above like Flame resistance, Composite epoxy laminate, High anti-tracking, Excellent dimensional stability, and it forms the yellow substrate just like ETL-CEM1-502(F TYPE). One of the applications of this type is

  • Power drive board
  • Suitable for silver/copper paste through hole
  • Suitable for SMT process
  • Suitable for HASL process
