Huai'an optimized price of heat dissipation copper foil
The production process of electrolytic copper foil is simple. There are three main processes: solution raw foil, surface treatment and product slitting. The production process seems simple, but it is a production process that integrates electronics, machinery and electrochemistry, and is particularly strict with the production environment. Therefore, the industry does not have a set of standard and universal production equipment and technology, and each manufacturer shows its own ingenuity, which is also an important bottleneck affecting the improvement of domestic production capacity and quality.

Copper clad laminate is the base plate for manufacturing PCB, which is an important type with large amount of materials. The manufacturing process of copper clad laminate is to impregnate glass fiber cloth, glass fiber mat, paper and other reinforcement materials with epoxy resin, phenolic resin and other adhesives, dry them to the first stage at appropriate temperature, obtain pre impregnating materials (referred to as impregnating materials), and then stack them according to process requirements and copper foil, The required copper clad laminate is obtained by heating and pressurizing on the laminator.

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.

Electrolytic copper foil is made by dissolving copper into copper sulfate solution, electrodepositing the copper sulfate electrolyte under the action of direct current in special electrolytic equipment to make the original foil, and then carrying out surface treatment, heat-resistant layer treatment, oxidation prevention treatment and other surface treatment processes on the original foil according to customer requirements.
