Abstract:
1. A pressure sensor apparatus, comprising; a mounting substrate having a plurality of wire bond pads; a pressure sense device having a pressure sense element, the pressure sense element including a diaphragm and one or more sensing components positioned on the diaphragm, the pressure sense device having one or more pads; a pedestal having a first surface bonded to the pressure sense device and a second opposite surface, the pedestal configured to reduce package induced stresses in the pressure sense device, the pedestal including an aperture in fluid communication with the diaphragm of the pressure sense device extending between the first and second surfaces of the pedestal; a solder material attaching the second surface of the pedestal to the mounting substrate, the solder material forming a hermetic seal between the second surface of the pedestal and the mounting substrate; a signal conditioning device electrically connected to said pressure sense device for conditioning a signal received from the pressure sense device corresponding to a pressure sensed by the pressure sense element, the signal conditioning device having one or more pads; one of more first wire bonds electrically connecting one or more pads of the pressure sense device to one or more of the plurality of wire bond pads of the mounting substrate; and one or more second wire bonds electrically connecting one or more pads of the signal conditioning device to one or more of the plurality of wire bond pads of the mounting substrate.
