5.3 Mounting TC35/TC37 onto the application platform
For the cellular application to operate reliably it is essential that the GSM engine is securely
attached to the host housing.
The TC35/TC37 board provides three mounting holes. To properly mount it to the host
device you can use M1.6 or M1.8 screws plus suitable washers. The maximum diameter of
the screw head incl. the washer must not exceed 4 mm.
To prevent mechanical damage, be careful not to force, bend or twist the GSM engine. Be
sure it is positioned flat against the host device.
Avoid placing the TC35 or TC37 board tightly to the host device. Instead, it is recommended
to set spacers between the module and the host device. If your design approach does not
allow for spacers make sure the host device provides an opening for the RF part.
