PCB prototype gold plating is mainly used to prevent oxidation. The purpose of gold plated PCB is to protect PCB from oxidation, so as to maintain the necessary solderability.

In the gold plating work, the PCB board remains flat. Gold plated PCB can effectively improve the weather resistance, salt spray resistance. There are also some to improve inventory cycle. Gold plating must be nickel plated, in order to prevent the penetration of the gold layer to the copper layer caused by infiltration of gold, so that the use of nickel layer isolation. Gold plated in order to allow PCB to have better weldability.
