nRF5340 Specifications V0.5.1 footprint

[Cy]

I am looking to get some clarification on the QFN94 footprint of the nRF5340.  There are four corner pads and they do not appear in the mechanical specifiications section 9.2. What are the sizes and where are they located, specifically. What are they electrically, NC? nRF5340

Hi

These corner pins are dummy pins and un-bonded. They give the package a better strength after SMT, especially when the package has an asymmetric design.

Best regards,

Hi, 

In order to generate a footprint for nRF5340 the mechanical dimensions of these four pins would be needed. They do not appear to be described in the data-sheet. Where can we find the dimension for these dummy pins? They should be soldered for best mechanical strength, right?
