Questions about this product
- What kind of work is this solder good for?
- It's made for general electronics soldering, like PCB assembly, wiring, and connectors. The built-in flux core helps it flow and wet cleanly for solid joints. It also suits hobby work such as Arduino projects and model building.
- Is this solder lead-free and what's the alloy?
- Yes, it's lead-free with a SN99.3 Cu0.7 alloy, meaning 99.3% tin and 0.7% copper. That makes it RoHS compliant and safer for modern electronics work. The tin-copper mix gives good conductivity and strong mechanical bonds.
- How much solder is on the reel?
- This reel holds 50g, a handy amount that's easy to store and use without bulk. It's enough for plenty of repairs and small projects. The same solder is also offered in larger 100g and 500g reels if you need more.
