I'm not even going to pretend I know how this fucker managed to do that. At first it looked like he used 30 gauge wire wrap wire, but I can see now that it is actually enamel coated magnet wire around 40 gauge in size. There are no holes on the board where he could have pulled the wires through to solder them in place so he had to manage soldering the wires to the PCB pads directly with the neighboring wires moved out of the way. The one dangling wire is a sign that he likely has many disconnects inside the birds nest under the BGA package. It looks like some shitty Intel proc so I don't know why anyone would even try to fix it this way.
