FR-4 copper clad laminated sheet uses glass fiber cloth as substrate material. After being immersed with epoxy resin and then baked into prepreg sheet, several prepreg sheets are then coated with copper foil on one side or both sides, and CCL is finally formed by hot pressing and curing. FR-4 CCL sheet has excellent thermal stability and machinability, widely used in the manufacture of printed circuit board (PCB) for television sets, computers, communications equipment and other electronic products.
