nRF52840-QFAA Footprint

[Jeff]

Is there an app note detailing the QFN48 package for the nRF52840, including solder paste recommendations?

The only documentation I've found are the reference gerbers?

Not specifically for the QFN48m, only for the aQFN https://infocenter.nordicsemi.com/topic/nan_040/APP/nan_040/nan40_intro.html

The QFN48 should be straight forward to generate with your PCB software tool.

Ideally Nordic would provide a drawing of the requirements for the QFN48.  Even simple 2-pad components often provide a recommended layout in their datasheets.  I am familiar with nan40, but that is a much different footprint.

I can generate or find a footprint, that isn't the issue  I just want to verify that it is the most optimal / recommended layout to start with so that manufacturability isn't compromised.
