Note: that 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.
