This course begins with an overview of the mechanical behavior of materials that are common
to electronic packages. The deformation characteristics and failure mechanisms such as delamination
and solder joint fatigue are discussed along with failure detection and evaluation methods. Modeling
assumptions and simulation techniques with finite element analysis are described in order to predict
solder joint fatigue by using commonly accepted failure criteria. Case studies concerning delamination
prediction and fatigue life prediction under thermal and bending cyclic loading will be presented by using ANSYS.
