10.4 Soldering Guidelines

The moisture sensitivity level of the BMF055 sensors corresponds to JEDEC Level 1, see

also

-

IPC/JEDEC J-STD-020C

"Joint Industry Standard: Moisture/Reflow Sensitivity

Classification for non-hermetic Solid State Surface Mount Devices"

-

IPC/JEDEC J-STD-033A "Joint Industry Standard: Handling, Packing, Shipping and Use

of Moisture/Reflow Sensitive Surface Mount Devices"

The sensor fulfils the lead-free soldering requirements of the above-mentioned IPC/JEDEC

standard, i.e. reflow soldering with a peak temperature up to 260°C.

10.5 Handling instructions

Micromechanical sensors are designed to sense acceleration with high accuracy even at low

amplitudes and contain highly sensitive structures inside the sensor element. The MEMS

sensor can tolerate mechanical shocks up to several thousand g's. However, these limits

might be exceeded in conditions with extreme shock loads such as e.g. hammer blow on or

next to the sensor, dropping of the sensor onto hard surfaces etc.

We recommend avoiding g-forces beyond the specified limits during transport, handling and

mounting of the sensors in a defined and qualified installation process.

This device has built-in protections against high electrostatic discharges or electric fields

(e.g. 2kV HBM); however, anti-static precautions should be taken as for any other CMOS

component. Unless otherwise specified, proper operation can only occur when all terminal

voltages are kept within the supply voltage range. Unused inputs must always be tied to a

defined logic voltage level.
