8.4.2.4 Bottom Layer – Ground Layer

The device has an exposed thermal pad on the bottom side for improved thermal performance. Conducting heat from the thermal pad to other layers requires thermal vias. Because the bottom layer is the secondary heat exchange surface to ambient, the thermal vias area must have low thermal resistance.
