Abstract
Method for fabricating a conductive elastomeric seal, which includes a set of springs plated with an electrically conductive material. Initially, the set of springs can be held in a z-axis position in a mold cavity shaped like a seal. A liquid elastomer can be injected into the mold cavity in such a manner that the elastomer can be over molded around and through coils of each spring. Finally, the elastomer seal with the springs can be removed from the mold cavity, when the elastomer is cured. Ends of each spring can be kept free from the elastomer during over-molding such that the elastomeric seal can provide an electrical contact with a pressure sensor die and electrical leads molded into a sensor housing. Such a conductive elastomeric seal can prevent a die-edge shorting with the sense die in order to achieve long-term sensor reliability and performance.
