Product Description
Tin Silver Copper SAC
Sn-Ag-Cu(SAC) is a lead-free solder alloy system for electronic soldering. 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.
Sn-Ag-Cu(SAC) is the most widely used lead-free solder alloy system for electronic brazing. For example, the melting points of SAC105, SAC305, SAC387 and SAC405 are all around 217°C. Among these solders, SAC305 is a typical representative, and its silver content is higher than that of SAC105, so its soldering strength, wettability, thermal fatigue and other properties are better than SAC105. Compared with SAC387 with higher silver content, the price is cheaper.
SAC305 (Sn96.5Ag3Cu0.5) solder has higher hardness, tensile strength, yield strength, shear strength, impact strength and creep strength than eutectic Sn63Pb37, and its wetting properties are also better than Sn-Cu and Sn- Ag solder. Typically used for reflow soldering, tinning and hand soldering.
