China’s electronic copper foil industry and its application in PCB industry

Development-status-of-China's-electronic-copper-foil-industry-and-its-application-in-PCB-industry

Electronic copper foil is a kind of copper foil, which is a negative electrolytic material. It is a thin, continuous metal foil deposited on the base layer of the circuit board. It is easy to adhere to the insulating layer, accept the printed protective layer, and resist corrosion. Then form a circuit pattern. Electronic copper foil is the main raw material for copper clad laminates (CCL) and printed circuit boards (PCB).
