The uncertainties related to geometrical dimensions and to the material properties such as Young’s modulus, can lead to mechanical failure. The probabilistic approach can be used to ensure more design robustness. Furthermore, the use of the reliability-based design optimization model reduces the structural weight in uncritical regions. It provides an improved design and a higher level of confidence in the design. REFERENCES 1. M. Pecht, P. Lall, and A. Dasgupta: “A Failure Prediction Model for Wire Bonds,” Proc. Intl. Symp. On Hyb.
