Surface Treatment introduction
Noimia has more than 10 years OEM experience, we can customized per your requested
There are three common treatments of conductors in electronic products: gold plating, silver plating and nickel plating like connector pins, shrapnel, terminals, etc.
A. Nickel plating--in order to increase the abrasion resistance of shrapnel or pins, in addition to beautify the appearance
B.Silver plating--in order to increase the conductivity of the conductor. If it is not good, the temperature of the connection part will rise quickly and high so that the connector will be burned out. The metal parts of some high-current connectors are usually silver-plated, such as the connection terminals of the ev charging gun, but the cost of silver plating is high.
C.Gold plating--better conductivity than silver plating, but more expensive than silver plating.
