At 0.1mm diameter, this wire is fine enough to route between closely-spaced SMD pads and under BGA packages without bridging adjacent conductors. The tinned copper construction solders cleanly with standard flux-core solder and flux paste, and the wire holds its shape when bent — essential for routing across component bodies and through tight spaces on densely populated boards.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWire Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.1mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTinned copper (Cu)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePCB trace repair, mobile phone board rework, BGA repair\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSolderability\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eExcellent (tinned surface, compatible with standard solder and flux)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMainland China\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhen to Use PCB Link Wire\u003c\/h3\u003e\n\u003cp\u003ePCB link wire is the correct repair method when:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBroken PCB trace\u003c\/strong\u003e — physical damage (drop, flex, impact) has cracked or severed a copper trace.
