ABSTRACT:
A hermetic seal is provided for a conductive feedthrough through a thin ceramic component by a platinum or palladium lead by sealing the gap between the lead and the ceramic with a copper-copper oxide eutectic. The lead may have a copper coating on it prior to and subsequent to formation of the copper-copper oxide eutectic.
