4.10 Mounting and installation

Appropriate installation and mounting to the host housing / enclosure is essential for reliable
operation of the GSM engine.
MC35 & MC35i
The MC35i 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, including the washer, must not exceed 4 mm.
To prevent mechanical damage, be careful not to force, bend or twist the GSM engine. Make
sure it is positioned flat against the host device.
Avoid placing the MC35i board tightly to the host device. Instead, it is recommended
to set the 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.
Avoid exerting any pressure on the shielding covers. Contact springs or other components
must not be fastened to the covers. In extreme conditions, you run the risk of short-circuit if
the cover was damaged or distorted due to pressure. Furthermore, the covers must not be
used to apply any solder joints.
For snap in concept please be aware that the MC35i PCB is thinner then the MC35
PCB.
