Sn-Ag-Cu Preforms

Sn-Ag-Cu (SAC) is the most common alloy in soldering electronics. Such as those alloys whose melting point is around 217℃, like SAC105(Sn98.5Ag1Cu0.5), SAC305 (Sn96.5Ag3Cu0.5)、SAC387(Sn95.5Ag3.8Cu0.7) and SAC405(Sn95.5Ag4Cu0.5) are usually used in reflow, wave and manual soldering.?

?

Among above, SAC305 are more wildly used. Compared with Sn63Pb37, it has better performance on stiffness, tensile strength, yield strength, shear strength, impact strength and creep strength;? compared with Sn-Cu/Sn-Ag preforms, it’s wetting properties are better.
