Hello Ya'll, I've got what may be a silly question, but why does it seem so important to everybody that you have x-ray capability if you're thinking about doing BGA? I know what most people will tell me; "Steve, that's a pretty silly question, it's because ya' can't see the solder joints ya' big boomerang!" Is that the only reason? Because if you stop and think about it, we were building boards with hidden solder joints a long time ago on SIMM's (the caps beneath the DRAM's), it never seemed like a big deal back then...and nobody was rushing out to spend $200,000 on a x-ray machine back then either... So what's the real reason? -Steve Gregory-
