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.

If the rough surface and pinholes appear at the same time when there are stains on the rough surface, it indicates that the stains are caused by the dirty electrolyte, and the dirt is attached to the copper foil in the electrolytic cell. If there are stains on the rough surface, the copper foil is not rough and there are no pinholes, it means that the workshop production environment is dirty, the air contains dust, or other suspended impurities fall on the surface of the copper foil.

According to the burning degree of the substrate in the flame and after leaving the ignition source, it can be divided into general type and self extinguishing type; According to the bending degree of the substrate, it can be divided into rigid and flexible laminates; According to the working temperature and working environment conditions of the substrate, it can be divided into heat resistant, radiation resistant, high-frequency foil clad plate, etc. In addition, there are also laminates used in special occasions, such as prefabricated inner laminates, metal based laminates, and copper foil, nickel foil, silver foil, aluminum foil, Kang copper foil, beryllium copper foil laminates according to the type of foil.

Copper foil is divided into calendered copper foil and electrolytic copper foil according to the preparation process, which accounts for the vast majority of the market. According to the Copper Foil Branch of China Electricity Association (CCFA), at present, domestic manufacturers mainly focus on the production of electrolytic copper foil. In 19 years, the domestic production capacity of electrolytic copper foil is expected to be close to 600000 tons, while that of rolled copper foil is only about 10000 tons.
