Opis:: In this article, a Low-cost measurement Infra-Red (IR) system for dynamic thermal testing of electronic devices is described. The element is powered by a step-function current and simultaneously temperature is measured by a fast single-detector IR head. The thermal impedance Zth(jω) is calculated using the Laplace transform and the Foster network is to get thermal time constants distribution.

Opis:: A new software tool for transient thermal analysis based on thermographic measurement of temperature is presented. In the proposed approach, temperature change after applying or removing power can be measured by a thermal camera or any contact temperature sensor. The software calculates thermal impedance in frequency domain and represents it in the form of the Nyquist plot. In addition, thermal time constant spectrum and cumulative structure function are evaluated. The software was developed in Matlab environment using in-built procedures for transfer function estimation. For the validation of the proposed tool, the results are compared with ones obtained using commercially available software.
