Soft Gold Surface Finish - 7pcb.com

The process for applying a soft gold surface finish is similar to hard gold in both cases, an electrolytic process is used to apply the finish, but the soft gold process requires that a Solder Mask first be applied. When soldered, soft gold remains in the alloy, and produces a stronger welded joint at the point of soldering or wire bond.
