Abstract

A Multi-Chip-Module or MCM (66) is mounted on a supporting motherboard (64). A plurality of first contact pads (99) are formed on the module (66) adjacent to its peripheral edge for interconnection with microelectronic components (70,72,74,76,78) mounted on the module (66). Second contact pads (94) are formed on the motherboard (64) adjacent to respective first contact pads (99). A flexible cable (96) includes controlled impedance microstrip or stripline conductor (98) with first and second gold dots (100,102) at their ends. A frame (104) resiliently presses the first and second gold dots (100, 102) into connection with respective first and second contacts (99,94) for interconnection thereof. The components (70, 72,74,76,78) on the module (66) can be hermetically sealed by a cover (80), and the module (66) and cable (96) can be hermetically sealed by a first resilient ring (112) which is compressed between the frame (104) and the cover (80), and a second resilient ring (114) which is compressed between the frame (104) and the motherboard (64). Alternatively, the cover (80) and the first ring (112) can be replaced by a cover (104a) which is integral with a frame (104'). An alternati…
