We are presently in the process of selecting an AOI manufacturer for our facility. We are mainly HMLV (mixed technology). I've investigated several including MVP, VI, Yes Tech etc... They all give a good presentation, but I would like to get input fr

have you tried a more agressive flux like water soluble to see if the problem goes away? Or can they be hand soldered with no problem? I am basically out of ideas other than a bad nickel or tin finish. The reflow profile didn't seem out of whack f

60-70% RH will be a challenge if you are running a water wash solder paste (and could be the reason you are seeing the problems). If you are running a no-clean, humidity should not be an issue. As long as the profile looks OK, I don't think the con
