A 50 g spool of lead-free SAC305 solder wire in a fine 0.5 mm (0.02″) diameter — ideal for both through-hole and SMT soldering work. The no-clean rosin core flux makes for clean joints without the need for post-solder cleaning.
SAC305 is a widely used RoHS-compliant lead-free formulation, making it a great alternative to traditional 60/40 leaded solder. The 50 g spool size is practical for hobbyists and makers — enough for plenty of projects without the bulk of a full 1 lb spool.
Key Features
- SAC305 Formulation – Sn 96.5%, Ag 3.0%, Cu 0.5% (tin/silver/copper)
- Lead-Free & RoHS Compliant – Safe for lead-free workshops and projects
- 0.5 mm Diameter – Fine gauge suitable for through-hole and SMT soldering
- No-Clean Rosin Core – Built-in flux for clean, reliable solder joints
- 50 g Spool – Convenient size for hobbyist and maker workbenches
Ideal For
- Electronics kit assembly and PCB soldering
- Surface-mount (SMT) component work
- Lead-free and RoHS-compliant projects
- General electronics prototyping and repair
Jargon buster
Plain-language definitions for the technical terms used above.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
