TerminalsThe specific role of surface plating metal has the following points:

  1. ProtectionTerminalsThe metal material is not corroded. Most terminal metal parts are made of copper alloy, which usually corrodes in the use environment, such as oxidation and vulcanization. Terminal plating is to isolate metal parts from the environment and prevent corrosion.
  2. OptimizationTerminalsThe properties of the surface of the metal piece, the establishment and maintenance of the contact interface between the terminals, especially the film layer control. In other words, metal-to-metal contact is made easier.
  3. EnhancedTerminalsAdhesion on the surface of metal parts, for metals with poor adhesion, it is usually necessary to hit the copper bottom before electroplating to enhance the adhesion.
  4. ImproveTerminalsConductivity of metal parts. For example, the conductivity of raw materials such as iron and phosphor copper is usually below 20%, and connectors with low impedance requirements cannot meet the requirements, so high conductive metals such as gold plating on the surface can reduce their impedance.
  5. ImproveTerminalsWelding performance of metal parts. Surface plating a certain thickness of tin and other substances can improve the welding performance of parts.
