When you say all over the board, please give more detail. Where are they located? [All over wave soldered portion, laminate only, solder mask only, solder only, specific components only, etc] When you say white residue, what color are they really?

Dave: Actually, I'm located in the South Bay (Santa Clara)! Good guess. Now, for more in-depth information: So far, the distribution has been limited to one board out of 10 assembled, so far from one lot. The components assembled are exclusively

I am researching articles with respect to intermetalics growth associated with gold as a final metalization. We are currently looking at a few options that include a 10uin flash followed by a 30uin selective and a total 30uin finish. The concern is

What kinds of equipment are you looking for? Alot of people arent explicit these days, guess it's the holidays. Had some rabel-rouser borrow my volt ohm meter and the next thing I know it's on the line being used as test equipment. Tried to give a

That's my exact suspiscion too. This guy is trying to find some type of "scapegoat" for some unknown defect that nobody can figure out. First, he'll try blaming the solder paste, thinking that the CM is too dumb to choose the correct soldering mate

Ron, have a look at http://www.fda.gov/cdrh/dsma/cgmphome.html It would be a nightmare, if your plant is not structured to support it. It's a huge pain in the fanny even when you (alledgedly) are. I'm not sure what you're pursuing, but if you're c

Sal: Now you�re talkin�, buddy!!! Darrell is correct. All things being equal, thermal relieved vias (and through holes) should be the hottest spot on the board at reflow temperatures. Vias are gonna take on solder like drippin�s take to biscuits.
