You should have a number of lighting options to deal with the low contrast lettering. Low angle, B/W, reverse color. etc... If I am reading you right, you might have your bridge inspector too far out on the lead banks, that it is seeing the silkscree

Has anyone experienced bridging on topside (solder destination side) surface mount devices after wave soldering? We x-rayed 100% of the placements after smt re-flow with no issues. When the same placements were x-rayed after the tht wave solder pro

You mentioned that you changed the layout some, and this can be essential in this type of process. If the SMT parts and TH leads have inadequate spacing on the bottom side, shorts may be inevitable (someone else will have to advise what the recommen

I successfully inspect solder on plcc's with angled cameras on the yestech we have. In the past I have successfully inspected for solder with angled cameras on mirtec machines for both plcc's and qfn's. Other than inspecting solder on those two types
