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.

Most copper foils used for domestic printed boards are 35um thick, and 50um copper foils are used as transition products. In high-precision hole metallized double-sided or multilayer board manufacturing, thinner than 35um copper foils, such as 18um, 9um and 5um copper foils, are expected. Some multilayer boards use thicker copper foil, such as 70um.

The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.

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.

According to the burning degree of the substrate in the flame and after leaving the ignition source, it can be divided into general type and self extinguishing type; According to the bending degree of the substrate, it can be divided into rigid and flexible laminates; According to the working temperature and working environment conditions of the substrate, it can be divided into heat resistant, radiation resistant, high-frequency foil clad plate, etc. In addition, there are also laminates used in special occasions, such as prefabricated inner laminates, metal based laminates, and copper foil, nickel foil, silver foil, aluminum foil, Kang copper foil, beryllium copper foil laminates according to the type of foil.

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.
