Chosen Solution

I’ve watched quite a few YouTube videos, where an M1 jumper is soldered to the logic board to resolve Touch IC Disease in iPhone 6/6+ devices. The wire of choice seems to be “whatever copper wire happens to be lying around”. If I were to purchase some copper wire specifically for this purpose, what diameter wire is recommended? 0.1mm? 0.08mm?

i use 45 awg enameled magnet wire from temco. works great
