The adhesives used for the laminates mainly include phenolic, epoxy, polyester, polyimide, polytetrafluoroethylene resin, etc. Therefore, the laminates are also divided into phenolic, epoxy, polyester, polyimide, and polytetrafluoroethylene laminates.

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.

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.

With the further competition in the market, even those with high added value have to be controlled from the production cost. Because the production requires very strict cleanliness of its electrolytic solution (copper sulfate solution), many filtration systems and liquid feeding pumps are repeatedly used in previous production processes. A new process flow is provided here, which can fundamentally control product quality and reduce production costs.

Excellent tensile strength and elongation High tensile strength and elongation under normal conditions can improve processing ability, enhance rigidity and avoid wrinkles to improve production qualification rate. High temperature extensibility (THE) copper foil and high tensile strength copper foil at high temperature can improve the thermal stability of printed boards and avoid deformation and warpage.
