If a technician could isolate a broken solder connection, it might be possible to "re-ball" the package and reinstall. There are services that say they'll do it, but I'd be skeptical that they could do it without returning it in nonworking pieces. It's almost impossible to probe (without test headers) a BGA package since the solder balls are hidden. It's not easy to remove all those packages and place new ones in there, or even to fix a bad solder joint. That's kind of the way it is with modern BGA assembly. Apple's contract manufacturers have workers who are very good at it. Or alternatively replace the entire device with a new or refurbished one, and send the old device back to the manufacturer for refurbishing. I don't mean to start a debate but does that mean that Apple replaces the entire motherboard in order to fix a bad SSD or RAM? ![]()
