Ken, best to use Sn62 (Silver bearing) solder on any component with Silver
plated terminations. It retards leaching of the Silver from the termination
during soldering.

Subject: [TN] Termination/Soldering Combination


We are planning to solder some surface mount capacitors with
palladium-silver terminations on our printed circuit assemblies using
tin-lead (SN63/37) solder.

Does anyone know of any long term reliability problems with this termination
alloy/soldering combination?

We can get these capacitors with nickel-tin terminations.

Given that our solder is tin-lead, does anyone know whether one of these
termination alloys would be preferable to the other?

Thanks for any insight you may be able to provide.
