Abstract:
Dual piezoresistive transducers formed into a single silicon die, are anodically bonded to a pedestal. Two separate pressure ports extend through a plastic housing. The port openings inside the housing are surrounded by a groove having a shape and size that accepts the pedestal. A thin, liquid adhesive is deposited into the groove and allowed to level out. The pedestal is placed into the adhesive and embeds itself therein. Adhesive overflow into the ports is avoided by dimensioning the groove and depositing an amount of adhesive that will fill the groove but not overflow when the pedestal is placed therein. Once the adhesive cures, the adhesive bond strength is greater due to the adhesive being in shear relative to the groove side walls and pedestal sidewalls. The grooved structure provides an apparatus and methodology for precise die mounting and media sealing.
