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.

Definition of electrolytic copper foil: it is formed by depositing copper ions in electrolyte on the round cathode roller of smooth rotating stainless steel plate (or titanium plate). The surface close to the cathode roller is called smooth surface, and the other surface is called rough surface.

If the surface stain is caused by environmental problems, the cleaning and improvement of the air conditioning filter system should be strengthened, or the wind speed should be reduced, and the small hairs on the air conditioning filter bag must be completely removed. And the fibers and powders on the polymer materials must be completely removed, which are very easy to cause stains. The air supply pipeline is easy to use plastic material, which does not produce fiber and is easy to clean with water, acid and alkali.

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.

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.
