Hi Jeff,

metallic or organic?

Subject: [TN] Dewetting of silver plating


Dear Soldering Gurus,

I currently have a dewetting problem with silver electroplated parts and I
was hoping that Technet would provide me with some suggestions.

A brief history - Our silver plating solution has been changed as our old
solution is no longer available. We are using water soluble 62/36/2Ag solder
paste. Our soldering process works very well on old tarnished components
from the previous plating solution, but demonstrates dewetting in components
plated with the new solution. The rest of the process appears to be the
same.

Any hints on particulars to watch out for or test would be greatly
appreciated.

Regards and thanks,
Jeff Brown
