   In the process of circuit board surface information processing, there is such a very common process, called sinking gold. The purpose of gold deposition process is to deposit nickel-gold coating with stable color, good brightness, smooth coating and good weldability on the surface of PCB printed circuit board. 

   In short, sinking gold is to use chemical deposition method to generate a layer of metal plating on the surface of the circuit board through chemical redox.
