Abstract :
A three-dimensional FEM (finite element method) analysis was performed on a flip-chip type BGA (ball grid array), and the resulting maximum equivalent plastic strain range (MEPSR) was used to determine the optimum material and structure for such packages. As a result, we were able to confirm the substantial influence of the combination of various materials, and structural parameters upon the package thermal fatigue life, and its nature. This also allowed us to optimize the material elements, an important parameter in package design, and the package structure
