6-70um High Performance Electronic Grade Copper Foil For Electromagnetic Shielding
Description
Copper foil has low surface oxygen characteristics, can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. It is mainly used in electromagnetic shielding and antistatic, and conductive copper foil is placed on the substrate surface , combined with metal substrates, has excellent conductivity and provides electromagnetic shielding effects. It can be divided into: self-adhesive copper foil, double-lead copper foil, single-lead copper foil, etc. Electronic grade copper foil (purity above 99.7%, Thickness 5um-105um) is one of the basic materials of the electronics industry. With the rapid development of the electronic information industry, the use of electronic grade copper foil is increasing. The products are widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, Civilian TV sets, video recorders, CD players, copiers, telephones, heating and cooling air conditioners, automotive electronic components, game consoles, etc. The demand for electronic-grade copper foil, especially high-performance electronic-grade copper foil, is increasing in domestic and foreign markets.
