Larry,

This formula was suggested to me recently for soldering an ENIG board, but
in the end 63/37 was found to be suitable. I was told that the silver
content improves the chances of good wetting on Nickel.

Got a question for everyone,

I just switched companies and the new company that I'm with now uses a
62/36/2 solder paste. I've always used the 63/37 formula. The guys who
decided to use the 2% silver are no longer with the company. My question
to you is, why would they want the 2% silver in the paste? They know
something I don't?!

Thanks,
Larry
