The electroplating function of the hardware terminal

In order to prevent oxidation of the hardware terminal materials, reduce contact resistance, increase solderability, increase wear resistance, and affect the electrical conduction of the circuit, the life of the connector, the hardware terminal is generally electroplated. Do you understand that different plating specifications have different effects on terminals? Here is an introduction to the role of each electroplating specification: 1. The role of gold plating Gold is an ideal contact plating material. It not only has excellent electrical and thermal conductivity, but also has good resistance in almost any environment. Corrosive. Because of these characteristics, gold is often used in the use of electrical connectors that require high reliability. But gold is very expensive, because alternative materials should be considered for this reason. Second, the role of gold alloy Gold alloy maintains many characteristics of pure gold while its price is much lower than pure gold. The use of gold alloys has achieved various successes. The degree of success depends on the characteristics of its alloying agent and the expected working conditions of the electrical connector. The alloy treatment will increase the electrical resistivity and hardness of gold and reduce the thermal conductivity and corrosion resistance of gold. The net effect is a slight increase in resistance. However, there is a potentially important reduction in environmental stability. The increase in gold hardness improves the durability of the contact coating. However, the properties of gold alloys are acceptable in a certain range of applications, so they are constantly being used.
