Precision electronics solder
This 0.6mm rosin-core wire uses a eutectic 63/37 tin-lead alloy that melts at a true point of 184.5 Celsius. The fine diameter and low melting temperature suit delicate circuit-board work where components are sensitive to heat. Each spool contains 12.5g of solder with 2.0% flux.
Sustained joint quality
Because the alloy has a single melting point rather than a range, it solidifies quickly and consistently during repeated joints. This behaviour reduces the risk of cold solder connections during long assembly or repair sessions. The rosin flux activates cleanly at working temperature.
Handy spool format
The lightweight 12.5g spool is easy to handle at the bench and stores without taking much space. Its 0.6mm thickness feeds smoothly through fine tips for surface-mount and through-hole tasks. The leaded composition is not suitable for lead-free or high-volume production requirements.

Questions about this item
Does the 0.6 mm rosin-core 63/37 solder produce much smoke or heat during long sessions?
The alloy melts at a single point of 184.5 °C, so a lower iron temperature is sufficient and less flux smoke is generated.
What equipment is needed to use this 12.5 g spool of 0.6 mm solder?
A temperature-controlled soldering iron, a stand with a damp sponge or brass wool, and a fume extractor or good ventilation.
Can this 63/37 tin-lead wire be used to repair joints originally made with lead-free solder?
Yes, the eutectic 63/37 alloy wets well at 184.5 °C and will fuse with existing lead-free joints when the iron reflows both metals.
