Copper foil is a cathodic electrolysis material, deposited on the base layer of the circuit board of a thin, continuous metal foil, it acts as a conductor of PCB. It is easy to bond to the insulating layer, accept the printing protective layer, corrosion after the formation of circuit pattern.
Copper foil is made of copper plus a certain proportion of other metals, copper foil generally has 90 foil and 88 foil, namely copper content of 90% and 88%, size of 16*16cm copper foil, is the most widely used decorative materials. Such as: guesthouses, buddhist temples, gold signboards, tile Mosaic, handicrafts and so on.
Copper foil has low surface oxygen characteristics and can be attached to a variety of different substrates, such as metal, insulation materials, etc., with a wide temperature range. Mainly used in electromagnetic shielding and antistatic, the conductive copper foil on the substrate surface, combined with the metal substrate, has excellent conductivity, and provide electromagnetic shielding effect. It can be divided into: self-adhesive copper foil, double guide copper foil, single guide copper foil, etc.
Electronic grade copper foil (purity more than 99.7%, thickness of 5um-105um) is one of the basic materials of electronic industry. With the rapid development of 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. TV sets, VIDEO recorders, CD players, photocopiers, telephones, heating and cooling air conditioners, automotive electronic components, game machines, etc. The demand for electronic grade copper foil, especially for high performance electronic grade copper foil, is increasing day by day in domestic and foreign markets.
Relevant professional institutions predict that by 2015, China's domestic demand for electronic copper foil will reach 300,000 tons, China will become the world's largest manufacturing base of printed circuit boards and copper foil, electronic copper foil, especially high-performance foil market is promising.
