A Quick Method for Calculating Temperatures Arising from Extended Microcircuit Heat Sources,

Abstract

In microelectronics the rapid degradation in reliability which occurs with modest rises in temperature makes it important that temperatures resulting from different geometries can be simply evaluated. One particular geometry which is becoming increasingly common is that of a long narrow strip heat source mounted upon the upper surface of a thin substrate which has a heat sink on its rear face. This report presents a series summation computation method suitable for pocket calculators, by which the state of convergence (SOC), in terms of maximum possible error, is calculated at each stage in the summation, thus enabling the calculation to be terminated as soon as the required accuracy has been obtained.
