I see. Are the pads castellated and manufactured by any of the regular Chinese cheap pcb fabs? Is so, how do you specify the castellation in the layout software?
This mod was part of SMD64 series that all share same footprint and loosely agree on placement on digital and analog in outs. For this module many pads are no connect.
