area at natural convection on FR4 board; The device was simulated on a 76.2 x 114.3 x 1.5 mm board. The 2s2p board
has 2 outer copper layers (2 x 70µm Cu) and 2 inner copper layers (2 x 35µm Cu). A thermal via (diameter = 0.3 mm and
25 µm plating) array was applied under the exposed pad and connected the first outer layer (top) to the first inner layer and
second outer layer (bottom) of the JEDEC PCB. Ta=25°C; The IC is dissipating 1W.
