When the external heat sink cannot be used, the relevant thermal resistance is the thermal
resistance from the junction to the bottom of the balls: RTH
The thermal path, in this case, is the junction, then the silicon, glue, CuW heat spreader, pack-
age Al2O3, and the balls (Sn63Pb37).
The Finite Element Method (FEM) with the thermal simulator leads to

such an assumption, RTH
To complete the thermal analysis, you must add the thermal resistance from the top of the
board (on which the device is soldered) to the ambient resistance, whose values are user-
dependent (the type of board, thermal, routing, area covered by copper in each board layer,
thickness, airflow or cold plate are all parameters to consider).
