ABSTRACT
New inverse analysis method is presented to identify coefficients of heat convection on
boundary of microelectronic packages. This approach adopts a modified Micro Genetic
Algorithm (GA) in finding the global optimum of parameters. A reduced-basis approach
is introduced in the forward heat transfer analysis so as to significantly improve the
efficiency in the calculation. Different identification methods are employed to identify heat
convection coefficients of a typical microelectronic package. Comparisons between
different methods are performed. Results show that the use of reduced-basis method
together with modified GA outperforms significantly. The present method of coefficient
identification is ideal for practical applications. It is efficient enough even for real time
and/or online analysis of both forward and inverse problem.
