Electronic connectors are an emerging electronic product industry. Since their birth, they have developed rapidly and have become an important electronic product industry. The products include RF coaxial connectors, EPT European connectors, optical fiber connectors, DRAWER connectors, and local broadcasting. Connectors, household appliances connectors, PC connectors, network connectors, microelectronic device connectors, explosion-proof electrical connectors, etc. In short, wherever there are electronic products, there must be connectors.
So what is the connector for? As the name suggests, it is used for electrical connection. Without connectors, the functions of electronic products cannot be exerted, and the flow of energy, electrons, and information cannot be circulated and transmitted. Our most common connectors are all kinds of plugs, sockets and various cables on the computer at home. Obviously, without these cables, all home appliances and computers cannot work, which shows the importance of connectors.
Like the electroplating of microwave devices, connector electroplating requires a large amount of precious metal electroplating solution. Therefore, saving precious metal resources is also an important issue faced by connector electroplating. The reason for putting this content in this chapter is that pulse electroplating is first and foremost used in precious metal electroplating, and connector electroplating happens to be an area where precious metal electroplating is more widely used.
In the electroplating of connectors, due to the high electrical performance requirements of the contact pair, the gold plating process occupies an obvious important position in the electroplating of the connectors. At present, except for some strip connectors that use the selective gold plati
