The Ultra Librarian provided footprint for the ADXL355 component does not match the recommended layout as shown in the datasheet.
Further the footprint pads seem to be a fair bit smaller than the pads on the device itself.
Possibly trying to do an SMD footprint rather than NSMD but copper area seems to match mask opening. So not sure.
Could someone take a look and recommend which way to go.
Hello rtresidd I need to circle internally about the origin of that reference footprint.
As reference for your design I can offer these measurements from the EVAL-ADXL355Z layout:

hope this helps,

rtresidd I have checked internally and the contact responsible for the ultralibrarian files is OOO until mid June. Thus, I will dig later this month about this topic, please ping me in a couple weeks if I am not back with feedback.
thanks for posting, hope we have been able to help.

Thanks Mario
I'll go with whats in the datasheet for now as it looks reasonable and appears to be whats used on the reference design.
Will get back in a couple of weeks to see if there's an update
Cheers
