The loss of heat from the surface of a PCB to the ambient air is difficult to compute as many process happen at the same time. This situation is much more challenging to describe mathematically since it involves the simultaneous processes of heat spreading by conduction and heat extraction over the surface of the board by convection and radiation. The efficiency of heat transfer from the PCB to air has a significant effect on the temperature difference between the ICs and the air.
