4.1 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-020C.
Leave “Pin 1 Indicator” unconnected during soldering.
Land pattern and soldering recommendations are available at www.st.com/mems
.
