WebMar 11, 2012 · The shear force and failure behaviors of the Sn-58Bi epoxy solder joints with various surface finishes under the high-speed shear test were investigated. The relationships between the shear speed, shear force, and fracture mode are elucidated in this study. The shear force of the Sn-58Bi solder joints increased with increasing shear … WebThe shear strength and fracture surfaces of Sn-Pb bump and Au stud bump for photodiode packages after isothermal aging testing were studied experimentally. Al/Au stud bumps and Cu/Sn-37mass%Pb solders were adopted, and aged at 373K and 423K for up to 900 hours to analyze the effect of intermetallic compound (IMC).
WebWhilst the construction of wafer bumps take many forms testing their quality by bond testing requires either pull or shear testing. Shear testing has the advantage of being easier than pull testing and when it produces the failure mode of interest it can be a good choice but in most cases pull testing is more likely to produce a bond failure rather than a failure in the … WebFor calculating the viscosity, the type of operation mode is irrelevant because the parameters shear stress and shear rate are both available, either as a preset value or as a result of the test. CSR and CSS preset profiles for flow curves (Figure 3.3): Preset rotational speed or shear-rate ramp, usually ascending or descending in steps
