Dynamics Modeling and Optimization of Beam in Flip Chip of LED Based on Rayleigh Method

Abstract

It is very important for superior performance beam in flip chip of LED to realize its work efficiently and accurate positioning. To obtain the superior performance of beam, its dynamic mode is built and carried out by Rayleigh method, and it is explored to find out the change trend of the natural frequency and deflection of the beam with its structural parameters. Based on the dynamic modeling of beam, optimization model of beam is built and its optimization solution is obtained by genetic algorithm. The results provide a theoretical basis on the further design and dynamic analysis of flip chip of LED.
