Abstract :
A flexible experimental setup enabling power control of a fully populated double-sided PCB has been realized, and is described in detail. A CFD model of a double-sided PCB housed in a sealed enclosure has been validated in a 19°C environment by means of temperature and flow measurement. The difference between simulated and measured component temperatures has been within 10%. Potential errors both in the model and in the experiments have been discussed and their impact on temperatures has been numerically evaluated.
