Want to make conductors by plating Silver-Palladium alloy
Silver 15%Pd plated conductors, instead of thick film Silver 15%Pd conductors.
Thick film has glass or some bonding agent, the thickness is over 12 um. This is very expensive. Why not sputter Ti/ Ni20%Pd then plate the Silver 15% Pd?
I have heard that it is possible to plate Silver with a small % of PD. 15% is small.
So who knows how to do this? That is plate Silver + 15% pd in one tank.
Note: All of the thick film Silver conductors either have Pd or Pt in them (you only need 5% Pt to accomplish the same goal as with 15%Pd. If we can get rid of the thick film it should be faster and cheaper to do all thin film + plating.
