Pure Copper foil has a low surface oxygen characteristics, can be attached with a variety of different substrates, such as metal, insulating materials, etc., have a wide range of temperature use. Mainly used in electromagnetic shielding and anti-static, the conductive copper foil placed on the substrate surface, combined with metal substrate, with excellent continuity, and provide the effect of electromagnetic shielding.
PCB Copper foil is a thin, continuous metal foil deposited on the base layer of a circuit board, It is easy to adhere to the insulation layer, to accept the protective layer of printing, corrosion after the formation of circuit patterns. As an important material to made of CCL and printed circuit board (PCB). PCB copper foil (purity of more than 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry.
