Sn100C Applications
Ideal sectors for silver-free alloy
Consumer Electronics
Smartphones, tablets, PCs, peripherals. Mass production where cost is critical but lead-free quality is needed.
LED Lighting
LED modules, drivers, LED strips. Excellent wettability for soldering on aluminum and copper surfaces.
Appliances
Washing machines, refrigerators, air conditioners. Economic alternative to SAC for white goods.
Standard Industrial
Controls, automation, instrumentation. Applications where SAC is over-specified and base Sn-Cu insufficient.
Sn100C vs SAC 305 vs Sn-Cu: Comparison
Positioning of Sn100C alloy versus alternatives
| Characteristic | Sn100C | SAC 305 | Standard Sn-Cu |
|---|---|---|---|
| Silver Content | 0% (none) | 3% | Significant savings |
| Relative Cost | Medium | High | -20-30% vs SAC |
| Wettability | Excellent (Ge) | Good | Superior thanks to Ge |
| Mechanical Strength | 40-45 MPa | 38-42 MPa | Comparable to SAC |
| Melting Point | 227°C | 217°C | +10°C vs SAC |
| Ideal Applications | Consumer, LED | Automotive, Critical | Quality/cost compromise |
Recommendation: Sn100C when SAC is too expensive but standard Sn-Cu doesn't offer sufficient quality. Excellent compromise for consumer electronics and LED. For critical automotive prefer SAC.
