OEM User’s Manual 81
Other manufacturers such as Molex offer similar connectors and latches, but these can
have different mechanical structures and PCB footprints to what we use on the Interface
Board. Table A-3 lists a pair of matched Molex parts that might be used.
Follow the PCB design and layout recommendations and considerations provided by the
manufacturer for the connector and latch that you select.
The RCM5600W may also be mounted with standoffs instead of a latch connector — this is
the type of mounting recommended for the RCM5600W to maximize both the vibration
resistance and the ground connections via the standoffs between the RCM5600W and the
board it is mounted on. The height of the standoffs will depend on the mini PCI Express
connector selected — Table A-4 provides some examples. Figure A-4 shows a footprint for
this mounting option based on the mini PCI Express connector in Table A-2.
