Hi Werner and H., Just to add some of the experiences I've had with AgPd finishes on capacitors, in wave soldering with no lead solders I have completely removed the termination from the device leaving only the ceramic. The finish completely dissolved into the solder. The only fix I could come up with was to change to a Ni solder termination on the device.
