High volume production of magnetic sensors for the automotive market

Magnetic sensors, like other electronic components used in automobiles need to be manufactured on-time in high volume at very high quality. Those requirements can only be fulfilled by a very specific process going from a six-sigma design over a sample-based qualification according to AEC-Q100 to the reliability screening tests run on full production. In this paper we discuss the motivations and principles of such an automotive quality system and then illustrate them by the example of a standard magnetic angular position sensor.
