Gold Plated Circuit Frames
When repairing gold fingers or contacts there are cases when a precut circuit frame which has laready been plated is preferrable to gold plating a repaired circuit pad.
In order to plated a repaired contact finger whihc is gold plated you can use a 2 step process or a single process. For the 2-step process the standard tin-finished circuit frames are used to repair the location on the PCB. This is followed by nickkel gold plating this material as a secondary operation. The downside with this technique is the thickness of the nickle and gold plating is not very controlled. In addition this is a 2-step process.
Alternatively a pre-cut circuit frame which already has been nickle gold coated can be cut frmae an used using either the epoxy or dry film techniques.
