Taizhou Preferred Antenna Copper Foil Price
Copper foil is not a traditional metal copper product. It combines design concepts such as composite material and nano material technology, and different internal microstructures, resulting in different properties from traditional pure copper. The application of copper foil mainly focuses on the characteristics of conduction, heat conduction and electromagnetic wave shielding.

Copper foil is a key conductive material in lithium ion batteries and printed circuit boards. It is a kind of negative electrolytic material, a thin, continuous metal foil deposited on the substrate of circuit board.

Although the thickness of copper foil gradually becomes thinner, power battery manufacturers use 6 μ When the product is less than or equal to m, the coating machine, winding machine and other key equipment as well as the technological level cannot solve the problems such as wrinkles, belt breakage and high-temperature oxidation encountered in the production process, which leads to the inability to mass produce ultra-thin copper foil with high yield.

The production of extremely thin copper foil has high barriers, and the products produced still need to meet many requirements of downstream lithium ion battery manufacturers. For investors, they should not only focus on the single index of thickness, not all manufacturers produce 6 μ M Copper foil is consistent, and the thinner the better.

Copper foil can also be divided into: single-sided treatment (single-sided hair), double-sided treatment (double-sided thick), smooth treatment (double-sided hair), double-sided light copper foil (double-sided hair) and very low profile copper foil (VLP copper foil) according to the surface condition. Post copper foil can be divided into electrolytic copper foil and calendered copper foil according to different production methods.
