In order to easily rework the module, it is suggested to add a 1.5 mm placement inhibit area
around the module. It is also suggested, as common rule for an SMT component, to avoid
having a mechanical part of the application in direct contact with the module.
The area under WIRING INHIBIT (see figure above) must be clear from signal or ground
paths.
PCB Pad Design
Non-solder mask defined (NSMD) type is recommended for the solder pads on the PCB.
