What is the function of electroplating gold on the surface of pogopin?pogo pin connector

　　The pogopin gold coating has a golden yellow appearance, good chemical stability, discoloration resistance, electrical conductivity, corrosion resistance and oxidation resistance, as well as good solderability, low contact resistance, and excellent thermocompression bonding properties, making electroplating Gold plating can be used both as a decorative coating and as a functional and protective coating.

　　Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis.

　　Functionality: Prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, corrosion resistance

　　Decorative: increase the surface color of pogopin, enhance the appearance and other functions.

　　In addition to gold plating, pogopin surface plating has other plating options, such as

　　Nickel plating: can enhance the corrosion resistance of the pogo pin;

　　Palladium-nickel plating: enhanced pogopin signal transmission, pogopin wear resistance

　　Different pogopin surface coatings can be selected according to their respective needs, and it is common to be nickel-plated and then gold-plated.
