A semiconductor system or sensor system in a housing which is butt-joined to a printed circuit board by soldering, at least some of the connecting surfaces not being soldered over their entire area, the connecting surfaces which are not soldered over their entire area being fixedly soldered in a first surface region to a section of a printed conductor, and in a second surface region the connecting surfaces not being fixedly connected to the printed circuit board, the securely soldered surface regions being situated closer to the semiconductor or sensor structure to be contacted than are the surface regions which are not fixedly connected to the printed circuit board.

QFN housing having optimized connecting surface geometry

An analyzer unit for the measuring signal of a micromechanical sensor having an input/output characteristic which is represented as a characteristic curve includes means for analog-digital conversion of the measuring signal and transmission means for transmission of the converted measuring signal or a signal that depends on the converted measuring signal. The transmission means is designed so that the characteristic curve has at least two ranges having different slopes. Different resolutions of the measuring signal are implemented through the different slopes of the characteristic curve. A suitably resolved signal is thus made available for applications having different sensitivity requirements.

Analyzer unit for the measuring signal of a micromechanical sensor

A sensor having a seismic mass and having an arrangement for detecting the deflection of the mass and converting it into an electrical signal; in at least one operating mode of the sensor, a mechanical stop asymmetrically limiting the deflection of the seismic mass with respect to a vibrational center position. An arrangement for symmetrical limiting of the signal provided on the sensor.
