Precision electronics solder
HengTianMei HTMSW63370850 is a rosin-core solder wire formulated for hand-soldering circuit boards, wiring and small electrical repairs. The 63/37 tin-lead alloy and 1.8% flux core suit hobbyists, technicians and DIY repairers who need reliable joints on through-hole and surface-mount parts.
63/37 eutectic alloy
The 63% tin, 37% lead ratio creates a true eutectic composition that melts sharply at 183 °C (361 °F) without a plastic range, so joints solidify quickly and resist cold-solder defects.
0.8 mm diameter, 50 g spool
At 0.8 mm the wire feeds cleanly through fine tips for dense board work, while the 50 g reel supplies enough length for many small jobs; larger production runs or thick power leads will need a heavier gauge or bigger spool.

Questions about this item
How does the 63/37 tin-lead ratio behave once it is in a real machine?
The eutectic 63/37 alloy melts sharply at 183 °C / 361 °F with no plastic range, so joints solidify fast and resist cold-solder defects during hand soldering.
What does the 1.8 % rosin flux core cap in practice?
The 1.8 % flux cleans oxidation and promotes wetting on copper pads, but leaves visible residue that should be cleaned with isopropyl alcohol for high-reliability boards.
What does the 0.8 mm diameter on a 50 mm × 18 mm spool need to fit or mount?
The 0.8 mm wire feeds from a 50 mm diameter, 18 mm wide spool that sits on any standard benchtop holder or clips directly to a pencil iron stand.
