Plating process can effectively improve connector performance

Electroplating is the process of plating a thin layer of other metals or alloys on some metal surfaces using the principle of electrolysis. The electroplating of electronic connector contacts is an important part of determining the quality of the connector. Because plating not only protects the base metal of the contacts from corrosion, but also optimizes the mechanical and electrical properties of the connector. Although most electrical connector contact springs are made of copper alloys that are susceptible to environmental corrosion such as oxidation and vulcanization, after electroplating, the plating layer can completely seal the copper alloys to avoid contact with the environment, thereby protecting the contacts.

1. Improve the mechanical properties of the connector

The plating process can affect the durability, wear resistance, ductility, hardness, mating force, and friction of the connector. High-quality coating materials and processes can greatly improve the mechanical properties of the connector.

2. Improve the electrical performance of the connector

By coating a metal film on the connector contact interface, the electrical performance of the connector can be optimized and a stable impedance can be maintained. The choice of coating material also has a certain influence on the electrical performance.

3. Improve the corrosion resistance of the connector

The contact plating of the connector plays an important role in preventing corrosion. The coating encloses the contact shrapnel from environmental contamination. Therefore, when selecting the coating material, it must be ensured that it has anti-oxidation and anti-sulfurization functions, in order to improve the corrosion resistance of the connector.
