flexibility Lithium copper foil With low surface oxygen characteristics, it can be attached to various substrates, such as metals, insulating materials, etc., and has a wide range of temperature applications. It is mainly used for electromagnetic shielding and anti-static. The conductive copper foil is placed on the substrate and combined with the metal substrate, which has excellent conductivity and provides electromagnetic shielding effect. It can be divided into: self-adhesive copper foil, double conductive copper foil, single conductive copper foil, etc. Electronic grade copper foil (purity of more than 99.7%, thickness of 5um-105um) is one of the basic materials of electronic industry. The electronic information industry is developing rapidly. The use of electronic grade copper foil is increasing. The products are widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, civil television, video recorders, CD players, photocopiers, telephones, air conditioners Electronic parts for automobiles, game consoles, etc. The demand for electronic grade copper foil, especially high-performance electronic grade copper foil, is increasing in the domestic and foreign markets. Relevant professional institutions predict that by 2015, China's domestic demand for electronic grade copper foil will reach 300000 tons, and China will become the manufacturing base of the world's printed circuit board and copper foil. The market for electronic grade copper foil, especially high-performance foil, is promising.
