Cem-1 PCB material is a bit unfamiliar to most people, but it is actually one of the substrates of printed circuit boards. It is low-grade in the PCB material industry and is only suitable for single-sided PCBs, but it is widely used.
The standard CEM-1 PCB material is a cellulose-based composite material with a layer of glass fiber laminate (FR-4) on the surface. Usually CEM-1 has a milky white color.
The feature of this material is that it is impossible to achieve metallization through holes, so it can only be used to produce 1-layer printed circuit boards.
The glass fiber fabric surface and paper core composed of CEM-1 composite material are combined with epoxy resin. Mainly used in the printed circuit board industry. Compared with paper grades, it is easy to punch, has excellent electrical properties and higher bending strength. CEM-1 PCB has excellent mechanical and electrical properties.
In the LED lighting market, most LED manufacturers use CEM-1 as a basic material. It can strike the best balance between heat dissipation performance and PCB cost.
Here are some of our samples:
