Soldering information
The LGA package is compliant with the ECOPACK^®, RoHS and “Green” standard.
It is qualified for soldering heat resistance according to JEDEC J-STD-020.
Leave “Pin 1 Indicator” unconnected during soldering.
Land pattern and soldering recommendation are available at www.st.com/mems.
5.3
High current wiring effects
High current in wiring and printed circuit traces can be culprits in causing errors in magnetic
field measurements for compassing.
Conductor-generated magnetic fields will add to the Earth’s magnetic field leading to errors
in compass-heading computation.
Keep currents higher than 10 mA a few millimeters further away from the sensor IC.
