Hi All!
Yesterday, Bill Kenyon sent me a very good picture of a solderball trapped in
flux residue that I finally got posted this morning on my web page at:
http:www.stevezeva.homestead.com
-Steve Gregory-
Steve- would you please post this photo on your web site? It's an excellent
microphoto of a solder ball on solder mask, showing the flux residue holding it
in place. Just washing with water won't do the job, unless it completely
dissolves the flux residue.
