63/37 Tin-Lead Solder Wire

This 63/37 tin-lead solder wire contains 1.8% flux in a 0.8mm diameter spool weighing 100g. It is intended for electronic soldering and maintenance on circuit boards and household appliances. The rosin core eliminates the need for separate flux application during standard joints.

Easy Spool Feed and No-Wash Residue

The wire feeds from an included spool inside a box, allowing controlled delivery to the iron tip. Low melting point and good fluidity reduce the risk of cold joints and bridging for both beginners and experienced users. Lead content requires ventilation and hand washing after handling to meet safety practice.

100g Capacity for Bench and Field Work

The 100g supply supports multiple repair sessions on radios, TVs, refrigerators and air conditioning units before replenishment. Strong adhesion and solid joint formation extend across typical through-hole and larger surface-mount pads. Very fine pitch IC work or high-volume production runs will exhaust the spool quickly.
