Sounds like bad BGA's to me. I suspect this is rare but you can get black pad on the BGA attach pads just like you get them on a PCB. Do you have un-processed BGA's?(still in package) I would have one tested (not by the manufacturer)!

You can also look to remove the silkscreen layer. Components on an assembly of this size can be easily identified with a seperate Assembly Drawing. But I'd also look to incorporate polarity indicators into the copper layers. That way you wouldn't ne

They are probably getting a little hot. So that leaves several courses of action. 1: Don't place them before reflow and hand finish. 2: Shield them with a little folded shield to decrease heat transfer. 3: Speed up the time through the oven, but th

Will the Pb part handle 240C? That is the first question that you need to answer. If it will then yes I would run the pbfree paste and profile. I assume that all other components are pbfree. If not, the same questions will need be asked as for th

Yes, electronics manufacturing is a volume producer of cardboard waste. If the components are ESD-critical, cardboard and most plastics are not ESD safe. Static charges can be generated on these materials during handling by the friction of dissimila
