Basic knowledge of connector terminal electroplating

Adddate:2021-08-05

 

1. Definition electroplating: it is a kind of metal electrodeposition process, which refers to the process in which simple metal ions or complex ions are discharged on the surface of solid (conductor or semiconductor) by electrochemical method and restored to metal atoms attached to the surface of electrode, so as to obtain a metal layer

2. Purpose electroplating can change the appearance by changing the appearance characteristics of solid, improve corrosion resistance, wear resistance, strengthen hardness, and provide special optical, electrical, magnetic, thermal and other appearance properties

3. Introduction to terminal electroplating most electronic connectors require external treatment of terminals, which generally refers to electroplating. There are two main reasons: one is to maintain the base material of terminal spring from corrosion; Second, optimize the performance of the terminal appearance, establish and adhere to the contact interface between terminals, especially the film control. In other words, make it easier to complete the metal to metal contact

The contact is the central part of the adapter to complete the function of electrical connection. Generally, the contact pair is composed of male contact and female contact, and the electrical connection is completed through the ***ion of female and male contact.
