About this product
A 0.8mm rosin-core solder wire with 63% tin content, supplied on a 100g spool. It is used for through-hole and surface-mount soldering of electronic components and PCBs. Being a tin-lead alloy, it melts at a lower temperature than lead-free solder, which suits repairs and prototyping.

Frequently asked questions
Is this solder lead-free?
No. A 63% tin alloy is a tin-lead solder. Use it in a ventilated area, wash your hands after handling, and do not use it where lead-free joints are required.
Do I need extra flux?
The rosin core provides flux for most through-hole and SMD work. Add flux paste for stubborn joints, oxidised pads or fine-pitch SMD components.
