WebNov 20, 2024 · The TEM specimen was prepared with a focused ion beam (FIB, JIB-4601F, JEOL). The joint strength of the SAC305 solder reflowed on the ENIG surface finish was measured with a high-speed ball shear tester (4000HS, Dage). The shear height was 50 µm and the shear speed was 2 m/s. The fracture mode was determined from the fracture … WebDec 6, 2013 · The shear test was performed on solder droplet samples by using the bond tester (Nordson DAGE 4000Plus). As per JESD22-B117A standard, the shear tool stand off should be no greater than 25 % (10 % preferred) of the solder ball height and tool shear speed should be typically in the range of 100–800 μm for low speed shear test.
