Frequently Asked Questions
Q: Does this copper jumper wire require sanding or stripping before soldering?
A: No — one of the standout advantages of this super fine 0.04mm copper jumper wire is that it can be soldered directly without any sanding or paint removal. This makes PCB trace repair faster and more straightforward.
Q: Is 0.04mm wire strong enough for PCB motherboard repair?
A: Yes. Despite its ultra-fine 0.04mm diameter, this copper wire features high elongation and good plasticity, meaning it holds up well during routing and soldering. Its compact structure and low inductance make it well-suited for dense, precision motherboard and circuit board repair work.
Q: How much wire do I get on each spool?
A: Each purchase includes one spool containing 100 meters (approximately 328 feet) of non-insulated copper jumper wire — more than enough for extensive repair projects or multiple repair sessions.
