Copper foil: a Yin quality electrolytic material, deposited a thin layer on the basal layer of the board, the continuous metal foil, as the PCB conductors. It is easily bonded to the insulating layer, for printing protective layer and etched to form a schematic kind.
Copper foil made of copper plus a certain percentage of other metals to fight the system from the general copper foil 90 foils and 88 foil two, is the copper content of 90% and 88%, size 16 * 16cm copper foil is the most versatile decorative materials. Such as: hotels, temple statues, gold standard, tile mosaics, crafts and so on.
The copper foil has a low surface oxygen characteristics, can be attached with a variety of different substrates such as metal, insulating materials, etc., with a wide temperature range. Mainly used in electromagnetic shielding and antistatic, conductive copper foil on the substrate surface, combined with the metal substrate, has an excellent conductivity and electromagnetic shielding effect. Can be divided into: self-adhesive copper foil, copper foil of the double guide Single copper foil. Electronic grade copper foil (purity 99.7% more than the thickness of 5um-105um) is one of the basic materials of the electronics industry electronic information industry rapid development, increasing use of electronic-grade copper foil products are widely used for industrial use calculator communications equipment, QA equipment, lithium copper foil
Child battery, civil TV, VCR, CD players, copiers, telephone, air conditioning, automotive electronic components and game consoles. Domestic and foreign markets for electronic grade copper foil, in particular the increasing demand for high-performance electronic grade copper foil.
