The same alloy can be supplied in different forms. Define the soldering method first, then choose alloy, flux and form — usually more effective than comparing price alone.
Lead-Free Solder
STAR.I supplies lead-free solder bars, wire and paste in Sn-Ag-Cu, Sn-Cu and Sn-Cu-Ni-Ce alloys. Lead is controlled below 1000 ppm, with SGS testing.

Product forms by soldering process
| Process | Typical form | Typical alloy | Notes |
|---|---|---|---|
| SMT reflow | Solder paste | SAC305, Sn-Cu | Stencil printing and reflow; match stencil, profile and cleaning method |
| Wave / hot-dip | Solder bar | Sn-Cu-Ni-Ce, Sn-Cu0.7 | Control pot temperature, composition and dross; test tin content regularly |
| Hand / iron soldering | Solder wire | SAC305, Sn-Cu0.7, Sn63Pb37 | Choose diameter and flux type by joint size |
| Plating / component leads | Anodes, tin-plated copper wire, alloy wire | Lead-free and Sn-Pb series | Confirm section shape, diameter and coating |
| SMT / wave support | Flux, cleaner, thinner, SMT adhesive | SICAL series | Match activity, solids, cleaning method and process |
