Over-Temperature Forecasts on Electronic Packages Through a Transient R–C Model

Abstract

Based on experimental data, a simple R–C (thermal resistance–heat capacitance) model with software precaution strategies are proposed in this paper to predict the steady-state temperature of the circuit in an electronic packaging in real time. Further developments on the new methodology lead to real time monitoring if input power and/or the environment are changing during operations. It is concluded that the new methodologies, which make the over-temperature prediction much more reliable, efficient, sensible, and faster, can be easily employed for over-temperature protection designs on electronic packaging.
