Note: there is no functional requirement for the large pad on the underside of the
32-QFN package to be soldered to the substrate. If the final application does require this
area to be soldered for mechanical reasons, the pad(s) to which it is soldered to must be
isolated and contained under the 32-QFN footprint only.
