Below is the Land Pattern Recommendation for the FMT1000-series. In the hatched area, designated with (E), don‟t
place (exposed) copper.

8.2 Mounting Considerations
The module contains a Micro Electro Mechanical System (MEMS) chip and is therefore sensitive for stress applied on
the PCB. To minimize stress apply the following design rules for the PCB and housing.
Avoid stress on the PCB by screwing/mounting it in a housing, applying unequal or excessive forces to the mounting
positions. Ideally the PCB should be mounted using mechanical dampeners.
 Avoid force applied on the PCB by push buttons; connectors etc. close to the FMT1000-series module.
 Avoid heat sources close to the FMT1000-series
 Avoid vibrations caused by speaker, buzzer etc.
