This is the smallest jumper wire that we’ve been able to find. It’s from Mechanic, so you know that it’s good stuff. We use this thin jumper wire for audio ic repairs, touch ic repairs and fixing torn pads. The wire is uncoated, so it’s best for fixing torn pads or running jumpers of short distance. If you run this wire a longer distance, then it’s possible that it’ll short out due to it be uncoated, so it’s best not to use this uncoated wire for long distance jumpers.
