6.2 Mounting AH3-W to the Application Platform
There are many ways to properly install AH3-W in the host device. An efficient approach is to
mount the AH3-W PCB to a frame, plate, rack or chassis.
Fasteners ca n be M2 screws plus suita ble wa shers, circuit board s pacers, or customize d
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
AH3-W to the external application.
Connector mounted on the AH3-W module:
Type: 52991-0808 SlimStack Receptacle 80 pins, 0.50mm pitch, for stacking heights of
3.0 or 4.0mm, see Figure 11 for details.
