title = "Comparison of numerical predictions and experimental measurements for the transient thermal behavior of a board-mounted electronic component",
abstract = "Numerical predictive accuracy is investigated for transient component heat transfer using a computational fluid dynamics (CFD) code dedicated to the thermal analysis of electronic equipment. The test cases are based on a single printed circuit board (PCB)-mounted, 160-lead PQFP component, analyzed in still-air, and both 1 and 2.25 m/s forced airflows. Three types of transient operating conditions are considered, namely (i) component dynamic power dissipation in fixed ambient conditions, (ii) passive component operation in dynamic ambient conditions, and (iii) combined component dynamic power dissipation in varying ambient conditions. Benchmark criteria are based on component junction temperature and component-PCB surface temperature, measured using thermal test dies and infrared thermography respectively. Using both nominal component/PCB geometry dimensions and material properties, component junction temperature is found to be accurately predicted for component dynamic power dissipation, in both fixed and varying ambient air temperature conditions.",
