: Sn-Ag-Cu (SAC) solders generally have better thermal cycling performance than eutectic Sn-Pb. However, their performance deteriorates significantly as the harshness of the thermal cycle increases, and the high-Ag SAC solders that perform best in thermal cycling have relatively poor drop impact properties
