LogiLink Lead-Free Silver-Bearing Solder Wire Sn99.3Cu0.7, 1 mm, 12.5 g Dispenser Box

For electronics work where residue and reliability matter, this lead-free solder wire from LogiLink stands apart with its silver-bearing alloy and no-clean flux core. The Sn99.3Cu0.7 composition delivers a melting point of 227 °C, making it suitable for both manual soldering and rework on temperature-sensitive boards. Unlike standard tin-lead solders, it meets RoHS requirements without compromising joint strength or electrical performance. The 1 mm diameter offers a practical balance between fine control and sufficient solder volume for through-hole and larger SMD pads. Packaged in a 12.5 g mini dispenser box, it stays protected and tangle-free until needed.

Highlights

• Lead-free alloy Sn99.3Cu0.7 (tin 99.3 %, copper 0.7 %) with silver-bearing designation
• No-clean synthetic resin flux core, 2.5 % flux content, halide-free (<0.05 %)
• Low spatter, low odor, transparent non-tacky residue after soldering
• Melting point 227 °C for efficient heat transfer and reduced thermal stress
• Compliant with RoHS and J-STD-004 classification REL0
• Convenient 12.5 g dispenser box with 1.0 mm wire diameter

In daily use

The no-clean flux leaves a clear, non-corrosive residue that does not require removal in most applications, saving time during assembly and repair. The low spatter and low odor characteristics improve workplace comfort, while the high electrical reliability ensures stable connections over the product's lifetime. Whether you are soldering connectors, wires, or PCB components, this solder flows smoothly and wets quickly on copper and tin-plated surfaces. The dispenser box allows one-handed feeding of the wire, keeping the work area organized.
