Uses and performance advantages of copper foil
Copper foil is a kind of cathode electrolytic material, a thin, continuous metal foil deposited on the base layer of the circuit board, which acts as the conductor of the PCB. It easily adheres to the insulating layer, accepts the printed protective layer, and forms a circuit pattern after corrosion. It is an important material for copper clad laminate (CCL) and printed circuit board (PCB) manufacturing. Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. Mainly used in electromagnetic shielding and antistatic. The conductive copper foil is placed on the surface of the substrate and combined with the metal substrate, which has excellent conductivity and provides electromagnetic shielding effect. Electronic grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry. The electronic information industry is devel...
