For a detailed analysis of the stress distribution within the solder joints and the determination of a damage criterion a 3D fmite element model of the test vehicle was utilised. Such a methodology is often needed to relate complex information in a simple manner to managers and non-experts in solder joint who work with computer server applications as well as for harsh environments such as those found in the defense, space, and automotive industries. Life time and stress data were merged to define the parameters for a Basquin life time model for the vibration load cases. Norris-Landzberg Norris and Landzberg proposed the plastic strain range is proportional to the thermal range of the cyclic loading ΔT. The material presented here is not limited to ceramic area array packages only, it can also be used as a methodology for relating numerical simulations and experimental data into an easy-to-use equation that captures the essential information needed to predict solder joint reliability. The test vehicles were analysed for their resonant frequency prior test and loaded with a sinusoidal vibration close to the resonant frequency for certain numbers of cycles.
