Hi Frank - No, I wouldn't recommend replacing the nickel with copper.
Copper will diffuse into/through the Ag finish creating an unsolderable
condition after an extended amount of time. The "extended" amount of time
will depend on the storage/use/handling conditions for the parts. You can
find some good info in Klein Wassink's book "Soldering in Electronics" ISBN
0-901150-14-2 on this issue. Good Luck.

Subject: Re: [TN] Ni plating and Immersion Au
I am plating stamped 1018-Steel parts with Ni and then Ag. I am then
soldering them together with 2%Ag solder. It is roughly 1" x 8". Should I
use Cu in place of the Ni?
