ABSTRACT:
The invention is an electronic component device in the form of an envelope including a glass cover and a glass shell bonded together for hermetically sealing a surface acoustic filter inside the envelope. Electrical connections are provided from the filter's electrodes to the outside of the envelope by means of through holes in the cover. Each through hole has an electrode disposed around its periphery on the upper and bottom surfaces of the cover and a conductive layer disposed on the internal surface of the hole. A metal foil is formed on the bottom electrode sealing the hole and pressed downward and deformed against a filter electrode to complete a connection between the filter electrode, the metal foil, the conductor layer and the electrodes disposed around the periphery of the hole, and to hermetically seal the hole.
