6.2 Mounting PH8/PH8-P to the Application Platform
There are many ways to properly install PH8/PH8-P in the host device. An efficient approach
is to mount the PH8/PH8-P PCB to a frame, plate, rack or chassis.
Fasteners can be M2 screws plus suitable washers, circuit board spacers, or customized
screws, clamps, or brackets. In addition, the board-to-board connection can also be utilized to
achieve better support.
For proper grounding it is strongly recommended to use large ground plane on the bottom of
board in addition to the five GND pins of the board-to-board connector. The ground plane may
also be used to attach cooling elements, e.g. a heat sink or thermally conductive tape.
To prevent mechanical damage, be careful not to force, bend or twist the module. Be sure it is
positioned flat against the host device.
6.3 Board-to-Board Application Connector
This section provides the specifications of the 80-pin board-to-board connector used to connect
PH8/PH8-P to the external application.
Connector mounted on the PH8/PH8-P module:
Type: 52991-0808 SlimStack Receptacle 80 pins, 0.50mm pitch, for stacking heights of
3.0 or 4.0mm, see Figure 12 for details.
