Hard Gold is used where either a very resilient surface finish is required, or in the case of edge connectors a wear resistant oxide free finish is required. Unlike electroless finishes, being an electrolytic process, an electric current is required to plate the gold onto the board. The thickness of the gold coating can be easily controlled by the plating current and plating time. The normal thickness of gold coating is **3 micros, and Sunthone is capable in fabricating maximum *0 micros of gold coating thickness.
Hard gold can also be used as a total
circuit board finish, in which case the cheapest production route can be
to photo print a negative image, plate the remaining exposed
copper with gold, then strip off the photo resist and use the
gold as an etch resist.
