PCB layout guidelines for DA14681 WLCSP package

I would like some guidelines/recommendations for designing the PCB artwork for DA14681 in the WLCSP package.
The package and pad details are in the datasheet.
I have not found any info on recommended solder mask patterns or signal fanout. It appears that in-pad micro-vias will be needed.

Hi DLWAY77,

Hi DLWAY77,

The following rescources provide information regarding PCB layout for the DA14681 (for both the QFN and WLCSP packages): 

https://support.dialog-semiconductor.com/system/files/resources/AN-B-061...

https://support.dialog-semiconductor.com/system/files/resources/AN-B-027...

In addition we publish the schematic, PCB layout and BOM for our DA14681 daughtercard (WLCSP package) so that customers can use this as a guide when developing their own PCB's:
