0.1mm Enamelled Copper Wire: For Trace Repair and Coils
0.1 mm | 10 m × 5 reels | Enamel burns off at soldering heat | No stripping needed
This is not solder. It is fine enamelled copper wire, sometimes called magnet wire, and it does two jobs on an electronics bench: repairing broken PCB traces and winding your own coils and inductors.
The enamel insulation burns away at soldering temperature, so you tin it straight from the reel without stripping anything. At 0.1 mm it is thin enough to bridge a lifted pad or run along a board without getting in the way.
What People Use It For
- Repairing broken PCB traces. The classic use. Bridge a cut or corroded track and the wire is thin enough to sit flat under a component.
- Phone and small board repair. Jumpering between pads where a track has lifted, common on water-damaged boards.
- Winding coils and inductors. Custom inductors, small transformers, RFID and induction coils.
- Prototype jumpers. Where a normal jumper wire is simply too bulky.
Working With It
- No stripping. Tin the end at normal soldering temperature and the enamel burns back on its own. Around 320°C works well.
- Tin before you place it. Far easier than trying to tin it in position on a crowded board.
- It is fine wire, treat it gently. At 0.1 mm it will break if you tug it. Anchor both ends properly.
- The enamel is the insulation. Once burned back it is bare copper, so keep the tinned length short if it is running near other tracks.

Frequently Asked Questions
Is this solder wire?
No. This is enamelled copper wire, sometimes called magnet wire. Solder is an alloy you melt to make a joint. This is a conductor you solder in place, used for repairing broken PCB traces and for winding coils.
Do I need to strip the enamel first?
No, and that is the point of it. The enamel coating burns away at normal soldering temperature, so you tin the end straight from the reel. Around 320°C does it comfortably.
What is it actually for?
Two main jobs. Repairing broken or corroded PCB tracks, where you solder a fine jumper between the two points, which is common in phone and water-damage repair. And winding custom coils, inductors and small transformers where you need thin insulated copper.
Is 0.1 mm strong enough for a trace repair?
For signal traces, yes, and it is thin enough to sit flat under a component. It is not for carrying significant current, so use something heavier for power rails. And anchor both ends, because at 0.1 mm it will break if it gets tugged.
