Abstract:
A flexible circuitry is populated with integrated circuitry (ICs) disposed along one or both of its major sides. Contacts are distributed along the flexible circuitry to provide connection between the module and an application environment. A rigid substrate is configured to provide space on one side where the populated flex is disposed while in some embodiments, heat management or cooling structures are arranged on one side of the module to mitigate thermal accumulation in the module.
Abstract:
A method and apparatus are disclosed in which a continuous elongated length of multi-conductor flat ribbon cable having a plurality of continuous signal and ground conductors for serially interconnects a plurality of terminal connectors. The signal and ground conductors include signal and ground wires which are disposed along the length of the cable in a predetermined arrangement with insulation material covering the wires. The insulation material is removed at predetermined positions along the length of the cable exposing the signal and ground wires for attachment to the terminal connectors.
Abstract:
A protector block assembly for coupling a plurality of surge protectors to multi-line telecommunications cables includes a multi-layer printed circuit, to which has been mounted at least two cable connectors, and a protector block having a plurality of sockets for receiving standard surge protectors. A plurality of pins electrically and physically connects the multi-layer printed circuit board to the sockets on the protector block in a manner that a unique signal path exists between each lead in each connector and one of the sockets on the printed circuit board. The multi-layer printed circuit board includes traces on multiple layers that have a width and a copper content sufficient to carry current surges without breaking down.
Abstract:
A device (100) having an external contact electrical connection (155) for providing an electrical interface to the device includes a housing member (222) having apertures (235, 335), and a flexible film substrate (270) having an electrically conductive pattern (275). Portions of the electrically conductive pattern defines contact areas (255, 355) for presenting the electrical interface of the device (100). These contact areas (255, 355) are rigidly positioned adjacent to the interior surface (324) of the housing (222) about the apertures (235, 335) such that the contact areas (255) are externally exposed through the aperture (235, 335).

A semiconductor memory control device includes a flexible circuit board having a plurality of panels and folded so that the panels are stacked on one another, a plurality of semiconductor elements mounted on the flexible circuit board, and a package enclosing the flexible circuit board and the plurality of semiconductor elements. A method of mounting semiconductor memory control devices in high density includes mounting a plurality of semiconductor elements on a flexible circuit board, forming an internally mounted module by folding the flexible circuit board in panels that are stacked in multiple layers, and enclosing the internally mounted module in a package.
Abstract:
Circuit apparatus comprises an integral structure of first and second multilayer wiring board portions and a flexible circuit portion. The wiring board portions each have at least circuit trace planes, ground planes and insulator planes. The flexible circuit portion includes at least one signal trace plane and at least one ground plane separated by at least one insulator plane; the singal trace plane of the flexible circuit portion being integral with a signal trace plane of each of the wiring board portions, the ground plane of the flexible circuit portion being integral with a ground plane of each of the wiring board portions, and the insulator plane of the flexible circuit portion being integral with an insulator plane of each of the wiring board portions. Selected ones of a plurality of electric contacts are connected to selected ones of the circuit traces of the circuit trace plane of the flexible circuit portions; others of the contacts being connected to the ground plane. A pin connector is conencted to the plurality of contacts and is arranged to electrically connect selected circuits traces and the ground plane of the flexible circuit portion to an interconnect backpanel, thereby electrically connecting the wiring board portions to the backpanel with minimum inductance.
