Material selection of pin header and female connector:
Among all the metal elements of the header and female connector, copper has the best performance in the conductive substance; followed by silver and gold, which can reduce the contact resistance, and are generally only used in connector electroplating materials. In the header and female connectors, pure copper is used for power, wire, information transmission, etc. At the same time, the pure copper material has good electrical conductivity, but in the electronic connector industry, its mechanical strength and heat resistance cannot reach According to the standard of the connector industry, it is necessary to add some alloying elements to improve its own mechanical strength and heat resistance. The thickness of the gold plating of the header and female connector affects the contact, and the thicker gold-plated contact will be better.
