Solder Wire 0.5mm 50g

This lead-free solder wire uses a Sn97/Ag0.3/Cu0.7 alloy with a 2% RMA rosin core. The 0.5mm diameter suits PCB work, connectors, wiring and general electronics repair. It is built for hobbyists, technicians and engineers who need reliable joints on circuit boards and small components.

Capacity and headroom

The 50g spool provides enough material for many small to medium soldering sessions. The alloy melts between 217225°C, reducing thermal stress on sensitive parts and working with most standard irons. Very large joints or high-volume production runs will need a larger spool. Buyers who want more solder per reel should look elsewhere.

Build quality and daily use

The low-residue, low-spatter formulation leaves clean, shiny joints that rarely require extra cleaning. A 0.5mm thickness feeds smoothly by hand and fits tight pads without bridging. The rosin core activates quickly, so flux application is not a separate step. Users who prefer a thicker wire for heavy gauge cables will find this diameter too fine.

Questions about this item

Will the 0.5 mm diameter work cleanly with the fine-pitch pads on my older Arduino shields?

The 0.5 mm diameter gives a good balance of precision and flow, making it suitable for fine-pitch pads on Arduino shields and similar boards.

How can I verify the Sn97/Ag0.3/Cu0.7 alloy is melting correctly on my iron?

The alloy melts in the 217–225 °C range; a clean, shiny joint with low spatter shows it is flowing as intended.

Does the 50 g spool include flux or do I need separate paste?

The wire has a 2 % RMA rosin flux core, so no separate flux paste is required for typical PCB and wiring jobs.
