Numerical simulation based on finite element method is an important tool in the thermal analysis of multichip
module(MCM). A three dimensional thermal model of a kind of MCM for special use was builted with ANSYS to calculate the
temperature distribution and power dissipation under air free convection condition. The effect of thermal enhancements such as
air forced convection and heat sink on temperature distribution and power dissipation of MCM was analyzed quantitatively.
