In our earlier web seminar, “PCB Thermal Modelling with Empirical Thermal Conductivity Methods”, we introduced the new effective thermal conductivity calculation that is available in FloTHERM XT known as “Empirical Calculation”.  Through comparison with customer testing and full explicit modeling, the results from the Empirical Calculation were validated. 

In the past, the interaction of the Thermal Territory with a PCB using the Analytical calculation demonstrated that the Thermal Territory affects the thermal results.  With the Empirical Calculation, this interaction changes and now the recommendation for when to use Thermal Territories is being updated.  This two-part series, first covers detailed descriptions and Analytical vs Empirical comparison when using Thermal Territories.  The second part will be reviewing examples on when to use Thermal Territories.
