<p>A polyimide adhesive is applied in liquid form between surfaces of a pressure transducer glass surface and a glass pedestal tube and maintained at room temperature, or below, for a period of 10-15 hours to allow the adhesive solvent to evaporate. After such time, the temperature of the transducer and attached pedestal tube is elevated over a period of time to about 320 DEG C. to completely imidize the polyimide adhesive. The pedestal is then fixed within an opening in a base portion of a case, and electrical conductors are connected between pins in the case and transducer contacts. A cover is hermetically sealed to the case to thereby encase the transducer.</p> |
