Lead-Free Solder Wire for Electronics

This 0.6 mm diameter solder wire uses a Sn99 Ag0.3 Cu0.7 alloy that meets lead-free compliance. The 2 % rosin core flux promotes clean, fast melting at 217 °C and smooth flow on circuit boards. Supplied as a 50 g spool, it is intended for electrical soldering tasks such as board assembly, cable repair and hobby projects.

Suits hobbyists and repair technicians needing

The 0.6 mm thickness works well for fine-pitch components and small joints. Users who require thicker wire for larger lugs, high-current connections or bulk tinning will find the diameter too small. The 50 g quantity is sized for occasional use rather than production-volume assembly.

Rosin-core flux eliminates separate flux application

The integrated 2 % flux core activates during heating, removing oxidation and improving wetting without extra paste or pen. This speeds up hand-soldering of TVs, radios, stereos, toys and similar devices. No additional accessories or software are included with the spool.

Questions about this item

Does the 0.6 mm Sn99 Ag0.3 Cu0.7 wire need a specific iron tip to melt cleanly?

The alloy melts at 217 °C / 422.6 °F, so any iron that reaches that temperature will flow the solder; a fine conical or chisel tip matches the 0.6 mm diameter well.

Will the 2 % rosin core flux work on older copper traces without extra cleaning?

The built-in 2 % rosin flux cleans oxidation as it melts, leaving a shiny joint on aged copper boards; wipe any residue with isopropyl alcohol if desired.

How can I confirm the joint is sound after soldering with this wire?

A good joint appears smooth, concave and bright silver; tug the lead gently — it should not move — and a multimeter continuity beep verifies electrical connection.
