Numerical Investigation On Dynamic Characteristics Of Bga Structural Integrity By Using Finite Element Method

摘要

A specified plastic ball grid array (PBGA) structural integrity prototype which contains different structure and material parameters is designed and manufactured. Based on investigation of the structural and dynamic parameters of PBGA prototype, the numerical simulation of the dynamic characteristics of the PBGA assembly prototype is analysed by using finite element method. The results show that the changing trends of the dynamic modal characteristics during the dynamic excitation. It builds a basis for future work such as the experimental test, structural design and reliability evaluation of PBGA packaging.
