Abstract
A pluggable connector capable of connecting a large number of electrical transmission lines per connector, and small enough to enable a large number of connectors to be added to a multi-chip module. For example, 5 or 6 of these connectors can add over a hundred coaxial cables to a module. Improved I/O communications is added to a module by such coaxial cables, since they can communicate very high frequency signals in noise prone environments. The pluggable connector is embedded in a multilayer module (e.g. ceramic or glass) for conveying digital information to transmission lines internal or printed on the surface of a module. Each connector contains a receptacle 19 having a silicon contact structure embedded in an edge of a multi-chip module. The contact structure is formed with a plug-receiving angle for deflecting multiple cantilevered plug contacts 17 into engagement with corresponding receptacle contacts 22. The silicon connector parts 19 have a thermal coefficient of expansion which matches that of silicon semiconductor and glass ceramic module 4 to maintain alignment over large temperature variations.
