Frequently Asked Questions
Q: What is non-insulated copper link wire used for in PCB repair?
A: Non-insulated copper link wire is used to create precise jumper connections on printed circuit boards (PCBs), phone motherboards, and other electronic components. The ultra-fine 0.04mm diameter allows technicians to bridge damaged traces or add connections in tight spaces with minimal footprint.
Q: Do I need to strip or sand this wire before soldering?
A: No — one of the standout features of this copper link wire is that it can be soldered directly without any stripping or sanding. The tin-coated copper surface bonds readily to solder, making repairs faster and more efficient.
Q: How long is each spool, and is it enough for professional use?
A: Each spool contains 100 metres of wire, making it well-suited for both professional repair shops and dedicated hobbyists. The generous length means you won't run out mid-project, and the compact spool design keeps the wire tangle-free and easy to dispense.
Q: What is the wire made of?
A: The wire features a copper core with a tin coating. This combination delivers excellent electrical conductivity, strong solderability, and good resistance to oxidation — ideal for precise electronics repair work.
