Frequently Asked Questions

Q: What is enameled copper jumper wire used for in PCB repair?

A: Enameled copper jumper wire is used to bridge broken or damaged PCB traces on circuit boards. Its ultra-fine 0.1mm diameter allows it to fit into tight spaces on mobile phones, laptops, and other compact electronics, restoring electrical continuity between solder points without needing a full board replacement.

Q: Do I need to strip the insulation before soldering this wire?

A: No — one of the key advantages of this enameled copper wire is that you can solder directly without scraping the isolation layer. The enamel coating burns away cleanly at soldering temperatures, making the repair process faster and more convenient.

Q: How long is the wire, and is 10 meters enough for professional use?

A: Each spool contains approximately 10 meters (about 393.7 inches) of wire. This generous length is well-suited for both professional repair shops and home hobbyists, providing enough wire for dozens of PCB repair jobs before needing a replacement spool.

Q: Is this wire suitable for applications beyond phone and computer repair?

A: Absolutely. This 0.1mm copper enameled wire is commonly used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, and electromagnets — any application requiring tight coils of fine, insulated wire.
