We know that terminal connectors are indispensable for conducting current or signals in equipment, so why use electroplating process for terminal terminals of electronic connectors? Why do terminals need plating?

1, anti-corrosion, anti-oxidation (such as nickel plating, chromium, zinc, etc.)
Our terminal materials are usually copper, iron, etc., which are easy to oxidize in the air. After electroplating a layer of metal with strong oxidation resistance, the corrosion resistance of terminal can be improved, and the performance of current and signal transmission can also be guaranteed.

2, enhance electrical conductivity (such as gold, silver, etc.)
In the original material such as iron, phosphorous copper conductivity is usually below 20%, for the low impedance requirements of the connector can not meet the requirements, the need to be in the surface electroplating and other high conductivity metal can reduce its impedance.

3, enhance electroplating adhesion (such as copper plating)
For metal with poor adhesion, copper bottom is usually used to enhance adhesion before plating.

4, improve the solder (such as gold, tin, etc.)
Because the original material for tin adhesion is poor, the surface of a certain thickness of tin and other substances can improve the solder parts.

5, beautiful (such as gold, silver, nickel, etc.)
After electroplating, the terminal metal usually has a more shiny appearance than the material and looks more beautiful
