... test is usually less than 10‐15°C/min. Nevertheless, TS tests have relatively high ramp rates (about 15°C/min or higher) and thus they are more efficient than the TC tests. Choosing an optimized cycle time for such TS tests is the driving force behind this study. Crack growth Fracture Finite...

... of chip resistors (1206, 0805, 0603, and 0402) are compared across the different profiles. The shear forces for the resistors were measured after assembly. The fracture interfaces were inspected using scanning electron microscopy with energy dispersive spectroscopy in order to determine the failure mode...

... superplasticity at temperatures greater than 50°C. From these results, deformation and fracture processes are reviewed, and the appropriate fracture mechanism is proposed. The elastic modulus for the five Pb‐Sn solders using the acoustic method are shown in Figure 7 . The elastic modulus increases...
