Customer Questions & Answers
What is the advantage of using a 63Sn/37Pb alloy with 1.2% flux in electronics compared with other compositions?
The 63% tin and 37% lead alloy is eutectic, melting at 183°C and solidifying without a pasty range, which reduces the risk of cold joints in electronics. The 1.2% flux helps remove oxides, improving wetting. Compared with other compositions, this option allows faster, cleaner soldering, but it is not compliant with RoHS regulations.
What is the typical wire length per spool, and what type of soldering irons is it recommended for?
A 400 g spool, with a diameter of 0.5 mm, contains approximately 216 metres of wire. It is compatible with most standard electric pencil soldering irons or stations, with power ratings from 15 to 60 W and fine tips. Below 15 W, it may be insufficient to melt the alloy efficiently.
How does this spool compare with lead-free options in terms of ease of use and solder durability?
Solders with 63Sn/37Pb are generally easier to apply and flow better than lead-free solders (such as SnAgCu), allowing shiny finishes and less long-term brittleness. However, lead is toxic and restricted under many regulations; where RoHS compliance is required, the lead-free option is mandatory, although it demands higher temperatures and more skill.
What type of work is this solder wire ideal for?
It is ideal for fine electronics soldering, repairs and assemblies on printed circuit boards.
What is the composition of the solder wire?
The composition is 63% tin and 37% lead, with 1.2% flux to improve solder quality.
What diameter is the solder wire?
The solder wire has a diameter of 0.5 mm, suitable for precise electronics soldering.
