Key Features
- 63/37 Tin-Lead Alloy with 2.2% Rosin Flux – Produces consistently shiny, smooth solder joints without dullness or cracking. Perfect for PCB assembly, SMD work, and wire splicing.
- Low Melting Point 361℉ (183℃) – Eutectic composition eliminates the pasty range, reducing thermal stress on sensitive components. No cold joints, no component movement during cooling.
- Choose Your Diameter – 0.6mm for fine SMD and micro-soldering, 0.8mm for general PCB and through-hole, 1.0mm for large joints and heavy wires. QA – Which weight? 50g is great for hobby projects, 100g for frequent repairs.
- Do I need extra flux for this solder? No. The built-in 2.2% rosin core activates during heating to remove oxidation. No external flux required – cleaner and faster.
- Is this solder beginner-friendly? Yes. Low melting point works with standard irons. Each spool is individually sealed to prevent oxidation. Great for first-time users and pros alike.
