Selective Silver Deposition/plating on Copper

A. Hi Felipe. Sometimes the obvious way is the obvious way :-)

Years ago I visited the (then) world's largest user and provider of plated busbar, and their solution was simply to do one wrap of platers tape for a clean demarkation line, then dip just the end into the plating tanks.

Regards,

A. Hi again, Felipe. Broadly speaking there is really only one way to do selective plating -- by exposing only the desired area to plating solution and plating current.

Partial immersion is one approach to that, which I've mentioned already. A second approach is brush plating where only the desired area is touched by the wet, electrified, plating brush/tampon. A third approach is masking with platers tape, vinyl plugs and caps, brush on masking agents, or in special plating machines that temporarily mask the areas where plating isn't wanted via rubber belts, etc. Good luck.

A. Hi cousin Tanmay. We appended your question to a thread which may have already answered it for you. If the volume is very very high you can use an automatic machine that temporarily masks one side of the button during the plating process. If the volume is lower, you can either use Brush plating equipment . . .

or you can apply some sort of masking to the back side of the button. Good luck.
