Tin Silver Copper Lead Free Solder SAC305 Solder Tabs For Batteries
Tin Silver Copper SAC305 Solder Tab Tin Silver Copper Preforme
Product Description
Features:
- Lead-free solder with a melting point of 217/218°C
- good wettability
- Excellent mechanical properties
- Good fatigue resistance and high reliability of welded joints
- Compatible with all types of flux
- Sn-Ag-Cu based solder alloy with better price and performance
Sn-Ag-Cu(SAC) is the most widely used lead-free solder alloy system for electronic brazing. Such as SAC105 (Sn98.5Ag1Cu0.5), SAC305 (Sn96.5Ag3Cu0.5), SAC387 (Sn95.5Ag3.8Cu0.7) and SAC405 (Sn95.5Ag4Cu0.5) are usually used for reflow soldering, wave soldering and manual Soldering, the melting point is around 217°C. Among these solders, SAC305 is widely used and supported by IPC. For SAC305 (Sn96.5Ag3Cu0.5) solder, its hardness, tensile strength, yield strength, shear strength, impact strength and creep strength are higher than those of eutectic Sn63Pb37. Wetting properties are also better than Sn-Cu and Sn-Ag solders.

Operation details:
- Solder pick up:
Use an anti-static jig to pick up the solder to prevent solder contamination and deformation.
- Flux Compatibility:
SAC305 solder is compatible with the major no-clean and water-soluble electronic grade fluxes currently on the market.
