This paper deals with the computation of thermal fields of power hybrid circuits using the finite difference method (FDM). The FDM is one of the classical methods used for temperature calculation of microcircuits having any shape and any boundary conditions. The equation written in the matrix form, describing thermal equilibrium, is solved using Choleski's method. The need for sufficient computer memory capacity is one of the main problems when using a small personal computer. This work attempts to show how to reduce the necessary computer memory capacity as much as possible. A compromise between memory capacity and CPU time is achieved.
