What's the minimum space between FlipChips for letting the eye-foot in between and down enough to see? /Ingemar

<< 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.

Hi Jurgen!
The system is already out there. Go to: http://csitechnet.com/sld001.htm and
you'll find a online presentation about the whole thing. I'm trying to get
management to buy it.
