ABSTRACT:
In accordance with this invention, hermetically sealed transition joint for use with a microwave package which has a receptacle including a side wall made of a first weldable material with a feed-through opening therein. The transition joint includes a first layer of a first material sized to extend across the feed-through opening and weldable to the side wall to form a hermetic seal. A second layer of a second material is explosively bonded to the first layer and sized to match and be received within the feed-through opening. A connector opening extends through the first and second layers. A pin connector unit made of the second material and having electrical pins extending therethrough is sized to fit within the connector opening and is welded to the second layer to form a hermetic seal. The first layer may be aluminum or aluminum alloy and the second layer can be any one of Kovar, cold rolled steel, stainless steel or iron-nickel alloy. Conveniently, the welding is done by laser welding.
