1. If the PIN of the connector is not plated, it will cause unstable signals and conductivity of the product.

2. A good connector PIN plating process will be gold-plated, because gold can better improve electrical conductivity and high thermal performance, as well as prevent oxidation and corrosion.

3. The gold pin of the connector can increase the service life of the product. The greater the thickness, the more obvious the effect.

4. Therefore, the benefits of the connector PIN pin for electroplating and gold plating are many, and several other electroplating processes are either expensive or have a low service life and are not resistant to plugging.
