Actually, CSPs and BGAs are not as difficult as you might think to
hand- assemble, given practice and a steady hand!. The solder balls
make them self-position by surface tension as long as they are roughly
in the right place to start with. I have a friend who routinely
replaces and reflows BGAs on cellphones with nothing more than a
hot-air tool. As for inspection - if you want X-rays, try your local vet, dentist or
hospital ! May take some trial & error with exposures but I'm sure it
would be viable if you only need the odd one or two every so often.
The biggest obstacle to cheap development with the zillion-pin BGA
devices is the need for multilayer PCBs.
