Products description:

CEM1 PCB  Composite epoxy materials (CEM) are a group of composite materials typically made from woven glass fabric surfaces and non-woven glass core combined with epoxy synthetic resin. They are typically used in printed circuit boards.

There are different types of CEMs:CEM1 material is for single side pcb only, it is the better than FR1 and FR2 material, is low-cost, flame-retardant, cellulose-paper-based laminate with only one layer of woven glass fabric.

CEM3 is a new material replace to FR4, because the production cost will cheaper, it is normal use to 2 layer PCB,  Its color is white, and it is flame-retardant.
