Adafruit Mini Leaded 60/40 Solder Spool - 0.3mm Diameter - 50 grams

High-quality rosin core welding wire guarantees easy soldering with a smooth flow, rapid soldering speed, and robust soldering points. Ideal for maintaining circuit boards, cable/TV/radio/stereo systems, toys, and other electronics.

This spool offers approximately 0.1 lb (50 grams) of 60/40 leaded solder, a perfect balance between large spools and compact vials. Composed of 60% Sn (Tin) and 40% Pb (Lead), with traces of Ag (Silver) and Cu (Copper), it provides exceptional soldering capability.

The 0.3mm diameter is specially crafted for delicate SMT (Surface-Mount Technology) tasks. The 'no clean' rosin core flux ensures precision without residue, making this solder perfect for assembling kits and learning soldering fundamentals.
