Smallest Accelerometer
At the same time that Bosch Sensortec announced its orientation sensor, they also announced their BMA355 accelerometer, which is distinguished by its size. Prior to this, the smallest footprint available for an accelerometer was 2×2 mm2. This guy is 1.2×1.5 mm2.
This was done via a die shrink. The MEMS is placed over the ASIC; the ASIC is more or less bonded straight down to its leads; it’s essentially chip-scale packaging.
In fact, they could have made the ASIC … Read More → "Smallest Accelerometer"
