Product Description

Weller T0051388699 Lead Free Solder Wire features a 1 mm diameter rosin-flux cored wire supplied on a 250 g spool, optimized for industrial electronic assembly and repair applications.

It is specifically formulated without lead content (0%) to meet environmental and regulatory requirements where lead-free soldering is mandatory.

The alloy consists of 96.5% tin, 3% silver, and 0.5% copper. The silver content enhances joint ductility and fatigue resistance, while the copper reduces whisker formation and strengthens mechanical integrity. The solder melts at 217 °C ensuring consistent reflow across standard soldering irons and equipment.

The rosin flux core produces minimal residues, reducing cleaning effort and protecting sensitive electronic components. This product suits manual and automated soldering processes including wave and selective soldering in manufacturing and maintenance environments.

Typical applications include repairs and assembly on SMT and through-hole printed circuit boards, as well as joining silver-bearing component leads in electronic control systems and automation modules.

Lead-free compliant solder wire with 0% lead for environmental safety. Optimized alloy for enhanced mechanical and thermal performance. Rosin flux core provides low-residue, high-reliability solder joints. Consistent melting temperature of 217 °C for precise soldering control.

Suitable for use in industrial, manufacturing, maintenance, and electronics laboratory settings. Supplied on a 250 g spool ideal for small to medium repair batches. This solder wire is manufactured in Japan, reflecting high-quality production standards.
