6.2 Mounting AC65/AC75 to the Application Platform
There are many ways to properly install AC65/AC75 in the host device. An efficient approach
is to mount the AC65/AC75 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. To help you find appropriate spacers a list of selected screws and
distance sleeves for 3mm stacking height can be found in Chapter 9.2.
When using the two small holes take care that the screws are inserted with the screw head
on the bottom of the AC65/AC75 PCB. Screws for the large holes can be inserted from top or
bottom.
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.
