Fine Soldering Wire Alloy
If your projects require high-volume, precision soldering, the Fine Soldering Wire Alloy, Flux 2.0%, Diameter 0.7 mm (400 g) offers the performance and capacity you need.
Designed for professional use, this solder wire delivers consistent flow, low spatter, and bright, clean joints. Its 2.0% activated flux core efficiently removes surface oxides, allowing excellent wetting even on fine-pitch components and oxidized pads.
The 0.7 mm diameter is an optimal choice for modern electronics, providing precise control on SMT components, connectors, and through-hole assemblies.
The large 400 g spool is well-suited for automated lines, repair stations, or long production runs, reducing interruptions caused by spool changes.
