Inverse Identification of Boundary Constants for Electronic Packages Using Modified Micro Genetic Algorithm and Reduced-basis Method
New inverse analysis method is presented to identify boundary constants for heat conduction in microelectronic packages. This approach adopts a modified Micro Genetic Algorithm (μG?) in finding the global optimum of constants. A reduced-basis approach is introduced in the forward heat transfer analysis so as to significantly improve the efficiency in calculation. Different identification procedures are employed to identify heat convective constants of a typical microelectronic package. Comparisons between different algorithms are performed. Results show that the use of reduced-basis method together with modified μGA outperforms significantly a conventional method. The present method of constant identification is ideal for practical applications. It is efficient enough even for online analysis of both forward and inverse problem.
