Tinned Copper Alloy Wire - Precision Core for PCB Assembly is engineered for fine electronic manufacturing, where stable conductivity, excellent solderability, and precise dimensional control are critical. Featuring a high-conductivity copper alloy core with a smooth and uniform tin coating, this wire is optimized for micro-soldering, signal integrity, and secure interconnections in densely packed PCB layouts.
Its ultra-smooth finish and tight diameter tolerance ensure clean joints, minimal resistance, and long-term reliability in high-density circuits.
Precision manufacturing ensures consistent diameter and high-quality surface finish
Tinned surface enhances corrosion resistance and improves soldering wettability
High conductivity copper alloy core maintains stable signal transmission
Suitable for high-density PCB layouts and fine electronic components
Customizable diameter, spool sizes, and surface treatments to match assembly lines
Micro-soldering for PCB and SMT (Surface Mount Technology) assembly
Jumpers, vias, and fine lead wires for multilayer circuit boards
High-precision wiring for consumer electronics, medical, and aerospace devices
Signal routing in communication modules and high-frequency boards
Compact interconnects in automotive electronics and IoT devices
