Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc. It has a wide range of temperature applications. It is mainly used in electromagnetic shielding and antistatic. The conductive copper foil is placed on the substrate and combined with metal substrate. It has excellent conductivity and provides the effect of electromagnetic shielding. It can be divided into self-adhesive copper foil, double-conductor copper foil, single-conductor copper foil and so on. Electronic copper foil (99.7% purity, 5um-105um thickness) is one of the basic materials of electronic industry. Electronic information industry is developing rapidly. The use of electronic copper foil is increasing. Products are widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, civil television sets, video recorders, CD players, etc. Copiers, telephones, air conditioners, automotive electronic components, game consoles, etc. The demand for electronic grade copper foil, especially high performance electronic grade copper foil, is increasing at home and abroad.
