Abstract:
The present invention provides a connector for transporting signals. The connector comprises a body made of a continuous body of material or alternatively of a plurality of superposed layers. The body includes a first terminal end, a second terminal end that is remote from the first terminal end and a three-dimensional arrangement of signal transmissive pathways within the body. The signal transmissive pathways are spaced apart from one another and extend side by side along a direction of propagation from the first terminal end to the second terminal end. The signal transmissive pathways are exposed at the first terminal end and at the second terminal end to allow external devices connected to the first terminal end and to the second terminal end to exchange signals via the signal transmissive pathways. The signal transmissive pathways are distributed in the body in multiple directions transverse to the direction of propagation.

Abstract:
A printed-circuit-type electrical contact pad having a plurality of electrically conductive metal traces and a plurality of protuberant electrical contacts projecting from the traces. The protuberances comprise an electrically conductive elastomer having a wide base portion anchored in the end of the trace by a truncated portion of the trace upstanding from the face of the pad. A denuded tip portion of the elastomer extends from the base portion for resiliently engaging a contact site on an electrical device to which the pad is coupled. A unique process for making the aforesaid pad is disclosed and claimed.
Abstract:
An elastomeric connector couples the terminal pads of an LCD with corresponding terminal pads of a printed wiring board (PWB). Conductive elements in the connector are subject to skewing at such an angle that the LCD must be adjusted relative to the PWB to attain pad alignment. Sense pads on the terminal strips are coupled to contact pads and are arranged so that a continuity test on substantially opposed contact pads will verify pad alignment. In one embodiment, one sense pad is narrower than the terminal pads so that even marginal continuity will assure proper alignment of the terminal pads. In another embodiment, a pair of sense pads on either one of the LCD and the PWB is bracketed by a pair of spaced pads on the other such that continuity is evidence of non-alignment.
Abstract:
This invention provides a connection structure and methods of forming the connection structure which combines the advantages of composite bumps and conductive films formed of conductive particles in a non-conductive binder. The conductive film provides conductive particles in a non-conductive binder which can be placed on the input/output pads of an integrated circuit element or substrate. The conductive particles contact composite bumps comprised of a polymer body, having a relatively low Young's Modulus, and a conductive metal coating to form the connection structure. The relatively low Young's Modulus of the composite bumps greatly reduce the recoil forces during bonding. Because of the low recoil forces the connection can be formed with reduced bonding force and forces tending to separate the connection once formed are reduced. The non-conductive binder is cured to form the adhesive between the integrated circuit element and the substrate.

A novel and improved device for interconnecting an integrated circuit package to a circuit board is presented. In accordance with the present invention an integrated circuit package having an central area devoid of surface contacts is positioned over a resilient or compressible connector system. The compressible connector includes an opening about its center which corresponds to the central area on the integrated circuit package. A component is mounted onto the circuit board within the opening of the compressible connector between the integrated circuit package and the circuit board.
Abstract:
An elastomeric member is incorporated between a conductor and a conductive interconnection bridge. This elastomeric member serves as a spring providing compliance to an interconnection so that the flatness requirements of an opposing mating structure may be relaxed. A flat metal mandrel is provided with an enlongated curved depression extending across a predetermined region where a resilient interconnection bridge is to be located. A nonconductive layer of Teflon is bonded to the surface of the mandrel. Grooves are ablated in a predetermined configuration down to the conductive surface of the mandrel using an excimer laser and a computer-controlled x-y table. Fineline electrical circuits are electrodeposited into the ablated grooves. The elongated curved depression is filled with a silicone material. The silicone material is permitted to cure to form a compliant elastomeric member having the shape of the elongated curved depression. An insulating backing is laminated onto the electrical circuits and the elastomeric member, and the completed resilient interconnection bridge is removed from the mandrel. Another method is used when the interconnection site is terminated on a circuit pad or on a high density linear connector configuration. In this method, elastomeric material is dispensed onto the circuit pad or along a line transverse to the high density linear connectors. After the elastomeric material has cured, electrical conductors are bonded thereacross to form raised compliant interconnection features.
