In connector electroplating, copper electroplating is particularly widely used.
Applications of Copper Plating
In connector plating, copper plating is typically used as a base layer, providing a solid foundation for subsequent plating processes. The copper plating layer enhances the connector’s electrical conductivity while improving its corrosion resistance. Furthermore, the copper plating layer provides excellent adhesion and surface smoothness for subsequent plating processes, ensuring the quality of the plating layer.
Characteristics of Copper Electroplating
Copper has excellent electrical conductivity, second only to silver among metals. Additionally, copper possesses good plasticity and ductility, which significantly enhances the electrical conductivity of connectors after copper electroplating. Furthermore, copper has a certain degree of corrosion resistance, enabling it to withstand external environmental corrosion to some extent.
