The ultra-fine 0.04mm diameter allows technicians to bridge damaged traces or add connections in tight spaces with minimal footprint.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need to strip or sand this wire before soldering?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long is each spool, and is it enough for professional use?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the wire made of?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is non-insulated copper link wire used for in PCB repair?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Non-insulated copper link wire is used to create precise jumper connections on printed circuit boards (PCBs), phone motherboards, and other electronic components.
