Do your boards only have three parts on them? Otherwise, i dont see how this is possible. Do you scrap the board if there is an issue or do you fix it and make it look like reflow soldering?

I assume you mean soldered and not welded. If the one pad that is having problems has a via hole next to it, it probably has more copper around it. Try running a hotter profile.

No pictures pre-paste. I have noticed on a few occasions a couple of boards that look like they have a slight discoloration on some areas of the board. Kind of like a shadow almost on the gold. Josh

Picture (img133) sure looks like black pad. Maybe you can compare the pic's yourself with the pictures in the ITRI Report on black pad. http://www.pwbrc.org/members/pdf/works99/Houghton.PDF

Patrick You're correct that black pad analysis is a distructive test. Kicking the lead-free dog certainly is easy [and somewhat fun] to do, but black pad is an equal opportunity defect. It affects leaded boards as well as it does with lead-free.
