1. Definition of electroplating: It is a kind of metal electrodeposition process. It refers to the process that simple metal ions or complex ions are discharged on the surface of solid (conductor or semiconductor) by electrochemical methods to restore metal atoms attached to the surface of the electrode, so as to obtain a metal layer
2. The purpose of electroplating is to change the appearance by changing the solid appearance characteristics, improve corrosion resistance, wear resistance, enhance hardness, and provide special optical, electrical, magnetic, thermal and other appearance properties
3. Introduction to the knowledge of terminal electroplating Most electronic connectors require external treatment of terminals, which generally refers to electroplating. There are two main reasons: first, to protect the base material of terminal spring from corrosion; The second is to optimize the performance of terminal appearance, establish and adhere to the contact interface between terminals, especially the film control. In other words, it is easier to complete metal-to-metal contact
The contact is the central part of the connector to complete the electrical connection function. Generally, the contact pair is composed of a positive contact and a negative contact, and the electrical connection is completed through the insertion of the negative and positive contacts& nbsp;
