  • Pressure sensor module and method for manufacturing the same
    Patent number: 7798008
    Abstract: For a pressure sensor module comprising a printed circuit board and a pressure cell, wherein the pressure cell has a measuring opening, and the pressure cell is encapsulated by injection molding compound in such a manner that the measuring opening is kept open, the pressure cell, as viewed from the measuring opening, is attached on the rear side of the printed circuit board. The printed circuit board has a recess in the area of the measuring opening, and the injection molding compound encloses the attachment area of the pressure cell on the printed circuit board. Thereby, the use of different adhesives, also soft adhesives, for the connection of the pressure cell with the printed circuit board is possible without this attachment area being attacked by the surrounding media.
