I have AgNO3 solution taken from
melting silver in Aqua regia, then
the solution added with Potassioum
Choloride. After that, a copper PCB
is dipped to the solution in order to get
a silvering pcb. But the silver did not
plate (coated) to the copper pcb.

Any one, please any idea to make
pcb coated with silver.

Thank you in advance.
