Silane coupling agent treatment: after anti oxidation treatment, the surface is sprayed with silane, which can improve the oxidation resistance at room temperature on the one hand; On the other hand, in high temperature pressing plate, silane can better combine copper foil and resin substrate through coupling, and improve peel strength. Post treatment process - drying. In order to prevent the harm of residual moisture, it must be dried at not less than 100 ℃ later, and the drying temperature cannot be too high.

Foil making material requirements: the thinner the thickness is, the higher the quality grade is, and the lower the impurity content in the electrolyte is required. In order to ensure the quality, the purity of copper must be greater than 99.9%.

Copper foil is not a traditional metal copper product. It combines design concepts such as composite material and nano material technology, and different internal microstructures, resulting in different properties from traditional pure copper. The application of copper foil mainly focuses on the characteristics of conduction, heat conduction and electromagnetic wave shielding.

The air supply of general air conditioning has a large impact. For the stains caused by the dirty electrolyte, the filtering of electrolyte should be strengthened. After being transferred from the electrolytic cell, the copper foil must be washed with electrolyte, because the surface of the copper foil is attached with organic matter or other impurities. The water pressure of copper foil washing must have enough pressure and a certain amount of water.

Speaking saliva splashes on the surface, and stains will appear when saliva is rolled up. A short time is a dark point, and a long time is a dark point. The size of the point is related to the saliva splashed on the 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.
