There are two methods for copper plating on contact shrapnel:


One type is chemical copper plating. Chemical copper plating is widely used in various industries, such as electronic appliances, hardware processes, handicrafts, furniture decoration, etc. Chemical copper plating has high stability and a wide range of application for working temperature and solution concentration. The copper layer is dense and has excellent adhesion. Basically suitable for copper plating on all metal and non-metallic surfaces. The coating thickness is uniform, the process equipment is simple, and the coating performance is good.


One type is electroplating copper. In the PCB manufacturing industry, electroplating copper has been used for many years. The electroplating copper solution for printed circuit boards is an acidic solution with high acidity and low copper content. It has excellent dispersion and deep plating ability, and the copper layer after plating has luster. The copper layer can decorate the surface of hardware contact with shrapnel and also have a corrosion resistance effect.
