I have a question about reflow soldering to gold with 2% silver paste.

I heard some  folk lore at our company about using 2% silver solder paste 
on gold plated lands. The legend states that 62/36/2 paste on gold has 
long term reliability implications, these joints being subject to 
dendritic growth to a greater degree than 63/37 solder to gold.

If anyone is aware of published data on this subject, I would be very 
grateful if you would give me the references so I may review the 
information.

Also, if anyone is using silver solder on gold at this time, I would be 
interested in hearing about your experience.

Please respond by the technet, to my e-mail address 
([log in to unmask]) or my phone (408/481-6047)
Thanks and regards
