It investigated the influence of heat exchange between each chip on MCM
and presented the mathematical calculation method for the junction-temperature of MCM chips under the condition of air convection
based on junction-ambient thermal resistance matrix. Comparison between the results of ANSYS finite element simulation and calculated results via this method under different combination conditions shows that the error margin of junction-temperature forecast by junction-ambient thermal resistance matrix is less than 6%
which indicates that the junction-ambient thermal resistance matrix can be applied to heat analysis for MCM to some extent.
