5.4 Moisture sensitivity level and soldering

The moisture sensitivity level (MSL) of the BMA020 sensor IC 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 IC 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.

5.5 RoHS compliancy

The BMA020 sensor IC meets the requirements of the EC restriction of hazardous substances

(RoHS) directive, see also

"Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the

restriction of the use of certain hazardous substances in electrical and electronic equipment".

5.6 Note on internal package structure

Within the scope of Bosch Sensortec’s ambition to improve its products and secure the product

supply while in mass production, Bosch Sensortec qualifies additional sources for the LGA

package of the BMA020.

While Bosch Sensortec took care that all of the technical package parameters as described

above are 100% identical for both sources, there can be differences in the chemical analysis

and internal structural between the different package sources.

However, as secured by the extensive product qualification processes of Bosch Sensortec, this

has no impact to the usage or to the quality of the BMA020 product.
