63/37 tin-lead alloy for electronics repair

This rosin-core solder wire contains 63 percent tin and 37 percent lead with 1.8 percent flux by weight. The 1.0 mm diameter and 100 g spool suit circuit-board work, TV and radio servicing, and general appliance repair. It is intended for hobbyists and technicians who need a traditional eutectic alloy.

Low melting point eases hand soldering

The eutectic composition melts at a single temperature, so the wire flows quickly and forms strong joints without a pasty range. Rosin flux cleans oxidation during the process, reducing the chance of cold joints. The main difficulty is lead exposure; adequate ventilation and hand washing are required after use.

Steady wetting during long sessions

Because the alloy has no plastic range, it continues to wet pads evenly during extended soldering without thickening or balling up. Flux activity remains consistent across the spool, so joint quality does not degrade as the reel empties. Users needing lead-free compliance or higher-temperature alloys cannot use this wire.

Questions about this item

How can I verify the Sn63 Pb37 solder wire is flowing correctly after setup?

The wire should melt at a low temperature, flow smoothly and form strong, shiny joints on circuit boards or appliance repairs.

What is included in the package and what must be purchased separately?

The box contains one 100 g spool of 1.0 mm Sn63 Pb37 rosin-core wire with 1.8 % flux; a soldering iron, tip cleaner and safety gear are not included.

Which diameter and weight version should I choose for general electronics work?

The 1.0 mm diameter and 100 g spool listed as H-10100 is the only version offered here and suits typical board, TV, radio and DIY soldering.
