Abstract
A method of manufacturing a hermetically sealed conductive feedthrough, particularly for use in ceramic substrates or housing, comprises the steps of inserting an active alloy containing preform into a predetermined insertion hole in a presintered ceramic article and heating the assembly to a temperature to achieve a brazing reaction at the interface of the article and active alloy to produce a hermetically sealed conductive feedthrough. The invention further discloses a non-melting connector pin which may be fixed to the active alloy feedthrough during the above heating step.
