PRESSURE SENSOR FOR MOUNTING ON THE COMPONENTS SIDE OF A PRINTED CIRCUIT BOARD

摘要

PURPOSE: A pressure sensor is provided to measure the precise pressure of the media which will be provided to sensors and mount on the components side of a printed circuit board. CONSTITUTION: A pressure sensor consists of a chip carrier made of electro insulating material and having an approximately flat chip carrying surface(4) and electrode terminals(7) which extend through the chip carrier (5) and are electrically connected to the semiconductor chip (6). The semiconductor chip (6) with the pressure sensor and electro circuit assigned to this sensor is fastened to chip carrying surface(4). The chip carrier (5) is open at the side (22) opposite to the components side (2) of the printed circuit board and has at its edges (24, 25) that delimit the opening (23) supporting means (26) that form positively and mechanically engage, without play, holding means (27) for an adapter (28) that can be set on the chip carrier (5), so that when the adapter (28) is set on the chip carrier (5) the holding means (27) and the supporting means (26) engage each other.
