Questions about this product
- What temperature should I set my soldering iron to when using this lead-free solder?
- This Sn99.3 Cu0.7 alloy melts at around 227°C (440°F), which is higher than leaded solder. We recommend setting your soldering iron tip temperature between 350°C and 380°C (662°F to 716°F). This temperature range ensures a clean flow and strong connections on your circuit boards.
- Which wire diameter size should I choose for my project?
- We offer seven wire diameters ranging from 0.5mm up to 2.0mm on a 50-gram spool. Choose the fine 0.5mm or 0.6mm sizes for delicate SMD components on circuit boards. For larger wires, connectors, or general electrical repairs, opt for the thicker 1.5mm or 2.0mm options.
- Is this solder safe to use for commercial electronics and school projects?
- Yes, this is a 100% lead-free, RoHS-compliant solder wire. Its safe formulation makes it ideal for schools, DIY workshops, and commercial product assembly. The integrated rosin flux core is non-corrosive, but we recommend cleaning any residue for the best performance.
