Abstract
A chemical sensor apparatus and method of making same is disclosed in which an ion sensitive silicon die is sandwiched between an elastomeric media seal and a conductive elastomeric pad contained within a housing. The conductive elastomeric pad contacts a printed circuit board (PCB) which leads from the housing. The die, elastomers and PCB are secured by a press-fit electrically conductive plug, which contacts and makes an electrical connection with the PCB. The plug functions as a counter electrode for the apparatus as well as a mechanical lock that seals the principal components of the apparatus within the housing in a substantially flush hermetic seal.
