Problems solved by technology

[0003] Among them, the silver-plated copper wire with the largest traditional consumption is called silver-plated copper wire or silver-plated wire in some occasions. In the process of drawing many times, the surface of the silver-plated conductive layer is scratched or the drawing oil and mold impurities in the process pollute the silver layer twice, and the damage to the surface of the silver layer in the post-process paralleling and twisting process is directly Affects the high-speed transmission of electrical signals, and at the same time uses silver-plated single-wire ply twisting to compensate for its single-wire process defects, which limits the application of ultra-fine silver-plated copper wires
It cannot meet the requirements for high-speed transmission of ultra-fine and high-frequency electrical signals in artificial intelligence and wearable products
