Mechanical stress
In general, it is recommended to place the MTi 1-series module in an area on the PCB with
minimal mechanical stress. The following paragraphs show causes of mechanical stress and
ways to reduce it.
Pushbutton contacts
Pushbuttons induce mechanical stress when used. Therefore, it is recommended to keep a
reasonable distance between a pushbutton and the MTi 1-series module.
Anchor points
Anchor points are usually a cause of mechanical torsional stress. The MTi 1-series module
should not be placed near an anchor point. Furthermore, since a plane is uniquely determined by
three points, it is recommended to affix the PCB with no more than three anchor points. More
than three anchor points over define the PCB plane and therefore induce mechanical stress. The
image below shows an example of a PCB with four anchor points that gives a maximum stress
in the centre of the diagonal crossover. Avoid placing the MTi 1-series module in such an area.
