System Plus Consulting is proud to publish the reverse costing report on the BMA250 3-axis MEMS accelerometer from Bosch Sensortec. The BMA250 is a low power digital accelerometer packaged in in a tiny 2x2x0.9mm³ QFN package. Major changes in the MEMS process were necessary to reduce the die area and the overall thickness.

The BMA250 is targeted for game controllers, mobile handsets, digital still and video cameras, 3D remote controls/mice, portable navigation devices, security and health.

This report provides complete teardown of the inertial MEMS with:

- Detailed photos
- Material analysis
- Schematic assembly description
- Manufacturing Process Flow
- In-depth economical analysis
- Manufacturing cost breakdown
- Selling price estimation

Reverse costing analysis represents the best cost/price evaluation given the publicallyavailable data, completed with industry expert estimates.
