Dear Members!
With interest I follow your discussion about X-ray testing of BGAs. I would
like to know, are there any other visual tests possible, to look under a
soldered BGA? For example, with a very tiny camera using a
glass-fibre-cable, say 0,5mm diameter? Is something like this in use? Or
makeable? Would need a very tiny optical system? I got the impression, to
solder BGAs reliable is a very delicate thing, isn't it?
Sorry for my stupid statements, but I haven't any experience in BGAs nor
testing of PCBs.
Jurgen.
