Calendered copper foil is a product made by repeatedly rolling and annealing high-precision copper strip (usually less than 150 microns in thickness) based on the principle of plastic processing (usually 4-100 microns in thickness and<800 mm in width). Its ductility, bending resistance and conductivity are better than those of electrolytic copper foil, and the copper purity is also higher than that of electrolytic copper foil.

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 electrolyte contains oil, paint, grease, sediment and other contaminants attached to the surface of copper foil. After being squeezed by the squeezing (water) roller, the contaminants are squeezed flat, some contaminants attach to it, and some contaminants attach to the guide roller. Because the dirt is squeezed up during the operation, the dirt has a head and a tail, and has a direction.

Copper foil is a key conductive material in lithium ion batteries and printed circuit boards. It is a kind of negative electrolytic material, a thin, continuous metal foil deposited on the substrate of circuit board.

The copper clad laminate is composed of copper foil, reinforcement material and adhesive. Plates are usually classified according to the reinforcement material category and adhesive category or plate characteristics.
