METHOD OF MANUFACTURING A COFIRED FEEDTHROUGH INCLUDING INJECTION MOLDING A FERRULE

摘要

Feedthrough assemblies (100) and methods of manufacturing feedthrough assemblies are provided. Methods include molding a ferrule (110) comprising titanium using metal injection molding and positioning the ferrule about at least a portion of an insulator (120), the insulator comprising alumina. Methods also include overmolding a ferrule about at least a portion of an insulator using metal injection molding, the ferrule comprising titanium and the insulator comprising alumina. Sintering densifies the ferrule and provides a hermetic seal between the ferrule and insulator. The insulator may be fired or unfired prior to sintering of the ferrule.
