Most copper foils used for domestic printed boards are 35um thick, and 50um copper foils are used as transition products. In high-precision hole metallized double-sided or multilayer board manufacturing, thinner than 35um copper foils, such as 18um, 9um and 5um copper foils, are expected. Some multilayer boards use thicker copper foil, such as 70um.

The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.

High end lithium battery copper foil needs to meet the requirements of high energy density, high safety, lightweight and other characteristics of power batteries, which is also the development trend of power batteries in the future. In order to meet the above characteristics, thinner lithium copper foil means smaller resistance, so the energy density and other performance of the battery will be improved. Moreover, the thinner the copper foil of lithium battery is, the lighter the weight of the corresponding battery will be.

Copper clad laminate is the base plate for manufacturing PCB, which is an important type with large amount of materials. The manufacturing process of copper clad laminate is to impregnate glass fiber cloth, glass fiber mat, paper and other reinforcement materials with epoxy resin, phenolic resin and other adhesives, dry them to the first stage at appropriate temperature, obtain pre impregnating materials (referred to as impregnating materials), and then stack them according to process requirements and copper foil, The required copper clad laminate is obtained by heating and pressurizing on the laminator.
