Mounting TC65 to the Application Platform

There are many ways to properly install TC65 in the host device. An efficient approach is to
mount the TC65 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 Section 9.2.
When using the two small holes take care that the screws are inserted with the screw head
on the bottom of the TC65 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.
All the information you need to install an antenna is summarized in Chapter 4. Note that the
antenna pad on the bottom of the TC65 PCB must not be influenced by any other PCBs,
components or by the housing of the host device. It needs to be surrounded by a restricted
space as described in Section 4.1.
