Immersion gold can improve the surface treatment of the PCB board.

To put it simply, immersion gold is a method of chemical deposition, which produces a metal coating on the surface of the circuit board through a chemical oxidation-reduction reaction.The advantage of the Immersion Gold process is that the color deposited on the surface is very stable when the circuit is printed, the brightness is very good, the coating is very flat, and the solderability is very good.
