You don't spray anything *under* a BGA, just a quick shot on top does
the trick.

If you have a bad solder joint under a BGA,how do you "fix" it?


Generally you don't, but you know to stop screwing around looking for the
problem elsewhere.

It may be possible to fix with a heat gun as a last ditch effort, but that
really could do further damage.
