Zusammenfassung:A medical device comprises a metal case having a hermetic seal; one or more Input/Output (I/O) conductors, wherein the I/O conductors pass through the hermetic seal such that a first end of the I/O conductors reside on a non-hermetic side of the hermetic seal and a second end of the I/O conductors reside on a hermetic side of the hermetic seal within the metal case; a ceramic substrate, wherein the one or more I/O conductors pass through the ceramic substrate and the ceramic substrate has a non-hermetic surface on a non-hermetic side of the hermetic seal; and wherein the non-hermetic surface of the ceramic substrate is a laser etched surface.
