High purity Soft temper pure copper foil
Copper factory, more than 12 years manufacture experience, attained ISO9001, work on OEM and ODM projects..
1. Introduction of the High purity Soft temper pure copper foil
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
