Yancheng Preferred Anti static Copper Foil Manufacturer
The foil of the clad plate can be copper, nickel, aluminum and other metal foils. However, considering such factors as the conductivity, solderability, elongation, adhesion to the substrate and price of gold, it is considered appropriate except for special purposes.

The production process of electrolytic copper foil is simple. There are three main processes: solution raw foil, surface treatment and product slitting. The production process seems simple, but it is a production process that integrates electronics, machinery and electrochemistry, and is particularly strict with the production environment. Therefore, the industry does not have a set of standard and universal production equipment and technology, and each manufacturer shows its own ingenuity, which is also an important bottleneck affecting the improvement of domestic production capacity and quality.

Calendered copper foil is the original foil made from copper plate by repeated rolling, and then roughened according to requirements. Due to the limitation of processing technology, its width is difficult to meet the requirements of rigid copper clad laminate, so calendered copper foil is rarely used on rigid copper clad laminate; However, because the bending resistance and elastic coefficient are greater than electrolytic copper foil, they are often used on flexible copper clad laminate.

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.
