ABSTRACT:
Electrical connectors are provided for enabling electrical access through a side wall of a microelectronic, sensor, or fiber optic package housing while maintaining hermeticity. These connectors include a connector body having an aperture therethrough and a coefficient of thermal expansion which is different than that of the housing. The connectors include a connector pin disposed through the aperture of the connector body and hermetically sealed to the connector body with an insulating composition or a ceramic insert bonded to the connector pins. Flange means are also provided for joining the hermetic electrical connector to the microelectronic package housing. The flange means includes upper and lower flanges metallurgically bonded together and comprising first and second metallic compositions respectively. The first composition is hermetically bonded to the connector body with a fusion weld having a heat-affected-zone which does not significantly affect the hermetic seals around the connector pins. The second metallic composition is readily weldable to the microelectronic package housing to provide the final hermetic coupling.
