Abstract:Taking a certain power device product as an example,the die temperature distribution of the product under normal operating conditions was tested by a thermal imager;the thermal simulation model of the product was established based on ANSYS software,the heat dissipation performance of the product was analyzed,and the experimental results were compared with the simulation results to verify the correctness of the simulation model;finally,based on the above model,the influence of the carrier material and thickness on the heat dissipation performance of the power device was analyzed to provide guidance for the process design of the product.

Keywords:power device;thermal imager;ANSYS software;heat dissipation performance
