know of to handle BGA is doing solder reflow. This can be

The only hitch is that you can only check if the joint is good by
powering it up. Otherwise you need access to an x-ray machine.
I've often wondered if it's practical to build a tabletop x-ray machine
for this purpose. Any ideas how much one would cost?
Not much point...I have a nearly-new commercial one, real-time
fluoroscope, not film, and I paid $100.00 for it. Keep an eye on the
surplus market.
