Silver plating Peels off copper [India] 

March 23, 2006

We do hard silver plating 10 microns on copper conductors and we are facing peel-off problem. Kindly help.

Is there any specification for checking/inspection of Adhesion of Silver plating on copper parts.

If the plate peals from a substrate, the part is either not properly cleaned or properly activated or preplate struck or there are delays in moving from one tank to another or the wrong process cycle. OR, a combination of all of the above.

Hello Ajay,

If you try to plate silver over copper directly this can happen; you need a base coat of copper and strike silver plating before plating on silver.
