RS PRO 0.5 mm Lead Solder, 183°C Melting Point
This rosin-based lead solder wire from the RS PRO range melts quickly and flows smoothly during use. Rapid melting means oxidisation of metal surfaces is reduced. This wire is used with a soldering iron to fuse electronic components to a circuit board.
The mild flux present in rosin prevents oxidisation and the residue left from use is non-corrosive and non-conductive of electricity. With a 60:40 ratio of tin and lead in the wire, it's further resistant to corrosion. This ratio also creates mechanically strong solder joints suitable for electronic devices.
The wire conforms to IPC-J-STD-004B specifications for regulating the flux used in solder wire. As part of the RS PRO series, it's been stringently tested to ensure consistent quality. Due to the lead content, this soldering wire is restricted to use by professionals and can't be used to solder products that comply with RoHS (Restriction of Hazardous Substances) standards.
