Jul 25, 2018· To understand the origin of hard and soft gold, it is best to know a little about the plating ''s not talk in front of the pickling process, basically is to get the "gold" the purpose of electroplating copper plating in the circuit board, but the "gold" can''t directly react with copper, so must first electroplating a layer ...
Gold plating is the electrochemical process of depositing a thin layer of gold on metal. Gold can be plated directly on a base metal or it can be applied over an undercoating such as nickel to improve adhesion of the gold itself. The purpose for gold plating includes conductivity, decoration, corrosion protection and reflectivity.
Basically the surface treatment has two essential functions. One is to protect the exposed copper circuitry on printed circuit board, the other is to provide a solderable surface for PCB assembly process. Hard gold plating (Hard electrolytic gold) consist of a layer of gold plated over a barrier coat of nickel.
A significant decline in plating rate will occur in a borohydride bath with the growth of free cyanide ions. A trivalent gold cyanide system can be replenished with cyanidefree gold compounds.
