Abstract
Abstract A high-density circuits connector assembly for interconnecting the edge conductors of module circuit boards with the I/O (input/output) circuits conductors of a cabling network of a data processing system. The connector assembly comprises signal and ground overlays formed by printed circuit techniques to provide conductive copper paths affixed to a flexible thin layer of polyimide material which are registered and attached at the edges of the module boards. An interconnecting contact pressure is achieved by a force mechanism comprising a resilient pad directly in contact with the overlays and a pressure-applying mechanism. The overlays function as a matched impedance I/O connector for interconnecting the module circuits boards with the other circuits wiring of a data processing system.
