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.

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.

At the same time of thinning, it is also necessary to improve the tensile strength, elongation and other indicators, otherwise it is easy to cause copper foil fracture, affecting the safety of the battery. Therefore, it is the general trend that the future use will be more light and meet the above indicators.

Backward key production equipment: for high-quality products with production thickness less than 0.05mm, multi roll rolling mill with width meeting user requirements shall be used. The rolling mill of some domestic copper processing plants can not be normally put into rolling foil production due to the lack of other equipment or the traditional product structure in the factory. However, some small processing plants have to use outdated production equipment and processes due to lack of key equipment or investment capacity, and copper foil product specifications and technical indicators are inferior to foreign products.

Small dirt, small exclamation mark. During the production of raw foil, the hair side is upward, and the dirt in liquid and air all fall on the hair side, which is printed on the smooth side after rolling. The reason is that the stains on the cathode roll are not dried. The surface temperature of the cathode roll is only 50 degrees, and the air temperature in the workshop is generally about 25 degrees. The surface hairiness is very good. The dirt itself has water, and the drying time is only 2-3 minutes. Therefore, the dirt on the copper foil cannot be completely dried.
