The role of the connector coating has four main points:

1. The coated connectors are not easily oxidized and cured

2. And can to some extent improve its mechanical properties, enhance its wear resistance

3. Also play the role of optimizing the electrical performance of connectors, building and maintaining a stable connector impedance

4. The noble metal coating is relatively simple to produce the metal contact of the interface and maintains the stability of the contact interface impedance

5. Ordinary metal coating surface covered with a thin layer of oxide film to ensure that the oxide film rupture in the connector, to ensure that the contact interface is no longer be oxidized. FPC connector
