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 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.

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.

Electronic circuit copper foil plays an important role in conducting electricity and heat in printed circuit board (PCB), and is known as the neural network on PCB. At present, copper foil for electronic circuits (PCB copper foil) is divided into two categories, namely conventional copper foil and high-performance copper foil.
