Physical variable detection device, e.g. acceleration sensor

摘要

The system includes a housing (2,4) and a sensor chip (3) which is installed inside the housing cavity (5). A wiring electrode (8,9) is also provided. The sensor chip is subjected to force in direction vertical or parallel to a circuit board (10) and transmits electrical signals corresp. to the size of the force exerted. The housing has a flat front side (4) end at an external side. The wiring electrode transmits an electrical signal, which is drawn from a wall of the cavity to the flat front side. The wiring electrode penetrates the housing to the flat front side end and has a front side bonding contact point zone (9) on the flat front side end. This zone connects the wiring electrode electrically and mechanically with the wiring (11) at the circuit board, if the housing is fixed at the circuit board.
