    Abstract: This patent discloses a resolderable connector particularly adapted for interconnecting multilayer modules with circuit boards and the like, but not limited thereto, the multilayer modules including a monolithic ceramic body with interconnected electrical conductors bonded to the ceramic. The modules include conductive terminations on at least one of the external surfaces of the ceramic body. Connected to these external conductive terminations are cuplike receptacles having a good solder wettable interior and a poor solder wettable exterior, the cuplike receptacles being connected to the conductive terminations as by brazing, but at any rate by a means having a higher melting temperature than conventional lead-tin solder so that bringing the receptacles to a temperature to heat the solder so that they may receive pins from projecting circuit boards does not cause release of the receptacles from the ceramic body.

    Abstract: The method and apparatus for coating workpieces (16) with a material involves boatless evaporation of the end of a wire or rod (12) made of said material. The end of the wire is heated by a radiant or inductive heater (14) to form a molten convex meniscus (13) thereon which serves as the coating source in the vacuum chamber (23).

    Abstract: A package for interconnecting a plurality of integrated circuit chips including a dielectric body having a plurality of intersecting planes and a plurality of metallized interconnection patterns located thereon. Conductive interconnecting lines connected to at least some of said metallized patterns located on different intersecting planes provide inter-plane electrical continuity, and input/output connectors connect to at least one of the metallized patterns for connecting to the outside world.
