Research on Producing Process and Performance of Pd-coated Copper Wire

The morphology of the surface of direct Pd-coated copper wire(Direct PCC) and Pd-plated copper wire was observed by SEM,and the performance of Direct PCC was researched.The results show that the technology of Direct PCC is better tnan the technology of Pd-plated copper wire.The technology of Direct PCC has many advantages,such as high elongation and breaking load,good surface quality,dense coating,high electric signal transmission performance.
