Description

[0002] Copper is widely used in electronic information, lubrication, catalysis and metallurgy and other fields due to its excellent performance and low price. But copper is easily oxidized in air, and the finer the particle size, the more serious the oxidation. In order to improve the oxidation resistance of copper, inert metal can be coated on the surface of copper. The inert metal layer can not only improve the oxidation resistance of copper, but also maintain its conductivity. Although tin is not an inert metal and is more active than copper, it is very stable at room temperature. Because a dense oxide film will be formed on the surface of tin, preventing further oxidation of tin. Therefore, tinning copper can improve the oxidation resistance of copper to some extent. Tinned copper has good stability, conductivity, wear resistance, corrosion resistance and electromagnetic shielding, and has good application prospect.

[0003] Before tinned copper is made into PCB board, tinned copper usually needs to be pressed into a certain thickness of plate structure from block for the next PCB board manufacturing process. However, the surface of the metal will be deformed due to friction and pressure during the pressing operation, and the compression of the metal in the thickness direction will cause part of the metal particles to flow along the horizontal (width) direction, thereby increasing the width of the metal plate. Therefore, after the pressing process, the metal plate still needs to be cut to the appropriate width size or to be pressed again, which is troublesome and affects the production efficiency. Therefore, in order to solve the above technical problems, the utility model provides a tinned copper pressing structure. UTILITY MODEL CONTENT
