The technical feature of electrolytic copper foil is that various technical conditions in electrolyte and additives must be strictly controlled, so equipment alone is not enough to produce high-performance copper foil; High performance has high requirements for the materials of anode plate and cathode roll in the raw foil equipment, the processing accuracy and consistency of the equipment; In the production process, the concentration of copper and acid in the electrolyte needs to be monitored and adjusted in real time.

The adhesives used for the laminates mainly include phenolic, epoxy, polyester, polyimide, polytetrafluoroethylene resin, etc. Therefore, the laminates are also divided into phenolic, epoxy, polyester, polyimide, and polytetrafluoroethylene laminates.

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 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.
