Abstract
A hermetic enclosure for an electrical component, particularly for a tantalum capacitor, and a method of forming it is disclosed. A silver container is provided having an open end at which an outwardly protruding flange is formed. A quantity of sealing glass is sealed to a lead and formed into a bead about the lead intermediate the ends thereof. A metallic member having an aperture therein is provided and the bead is sealed to the surface of the aperture bordering portion of the metallic member. A silver ring is disposed on the surface of the metallic member and the peripheral portion of the metallic member is folded over and pressed into a portion of the silver ring to form a compression seal therebetween. This assembly is disposed adjacent the outwardly protruding flange of the container with the lead extending from within the container to the exterior thereof. The protruding flange is folded over the metallic member so that it contacts the exposed inner portion of the silver ring where it is hermetically sealed to the silver ring.
