Solder-through enamel wire, an essential of your soldering toolkit for repairs, hacks, and various bodges to work around the bugs you designed right into your pcb.
Enamel coating burns off at soldering temperatures.
This is very very fine wire at 0.1mm diameter, suitable for carrying maybe 30mA - logic bodges not power bodges!
Approx 8m on a spool so I’m told, but I haven’t unspooled one to measure!
Note there is a small blob of glue on the outer layer of the spool holding down the loose end, if that matters to you.
All of our products are shipped from Christchurch, New Zealand using CourierPost for NZ, and Airmail for international.
