Abstract:
A biocompatible, micro-fabricated ribbon cable is described in which at least one set of conductors diverges laterally into a bypass wing that forms an aperture through the ribbon cable. The bypass wing is folded in a line through the aperture and over a central portion of the ribbon cable, resulting in a ribbon cable with a narrow, stacked region. The narrow region can fit through small incisions in membranes, such as through an incision in a sclera of an eyeball. The ribbon cable can have an integrally-formed electrode array for attaching to a retina of an eyeball and other electronics for sending signals to the electrode array.
Abstract:
A plurality of protruding substrate portions (12) is extended from positions placed at an interval from each other along a peripheral edge of a wiring substrate (10). Each of the protruding substrate portions (12) is provided with wiring terminals (15), (16) electrically connected to each of a plurality of electrode terminals provided to an electrical instrument substrate. A cut-out part (18) is formed in a peripheral edge (13a) between the protruding substrate portions (12) in the wiring substrate (10).
Abstract:
A method for fabricating an electronic device or circuit, respectively, comprises providing a flexible substrate (1), defining onto the flexible substrate (1) electric components (2, 3, 3’, 3’’, 3’’’, 7, 11, 12) and interconnects (8), introducing out breaks (4, 4’, 4’’, 4a-4s) in the flexible substrate (1) between the electric components and/or interconnects, and forming the flexible substrate (1) into a deformed configuration by deforming, particularly folding, parts of the flexible substrate as determined by the breaks (4, 4’, 4’’, 4a-4s).
Abstract:
The invention provides an electro-optical device capable of simplifying a terminal connecting process and increasing the ratio of a display area. Connection terminals connected to a scanning driver IC chip 32 are arranged on a short side of a wiring connection area 25A of a second substrate 25 in a liquid crystal display panel 21, and the connection terminals and connection terminals arranged on a long side of a wiring connection area 24A of a first substrate 24 are connected from the same direction with a single flexible printed wiring board 22. For this reason, convenience of the flexible printed wiring board 22 can be improved. In addition, it is possible to reduce the projection size of the wiring connection area of the first substrate 24, and the ratio of the display area in the whole liquid crystal panel 21 can be increased.
Abstract:
Un boîtier à superposition destiné à une pluralité de dispositifs à circuits intégrés (76) utilise une plaquette (61) en matière d'interconnexion souple pliée en un agencement à plusieurs couches de doigts parallèles en forme de plaquettes (61) sur lesquels une pluralité de dispositifs à circuits intégrés sont montés en surface. Les fils (71, 73) des dispositifs à circuits intégrés (76) sont fixés à des liaisons d'interconnexion (81, 83) de la plaquette d'interconnexion souple (61). Une pluralité de plaques de dissipation thermique (115) sont intercalées avec les doigts pliés en forme de plaquette (61) de la superposition, de manière à venir au contact des dispositifs à circuits intégrés (76) montés sur les doigts en forme de plaquette (61). Les plaques de dissipation thermique (115) sont retenues par des blocs d'espacement thermoconducteur (131, 133) le long de leurs bords. Les blocs d'espacement (131, 133) sont serrés ensemble en une structure stratifiée compacte, de manière à former un support rigide soulageant les contraintes mécaniques au niveau des plis des doigts en forme de plaquettes (61).
Abstract:
Provided are electrical harness assemblies and methods of forming such harness assemblies. A harness assembly comprises a conductor trace, comprising a conductor lead with a width-to-thickness ratio of at least 2. This ratio provides for a lower thickness profile and enhances heat transfer from the harness to the environment. In some examples, a conductor trace may be formed from a thin sheet of metal. The same sheet may be used to form other components of the harness. The conductor trace also comprises a connecting end, monolithic with the conductor lead. The width-to-thickness ratio of the connecting end may be less than that of the conductor trace, allowing for the connecting end to be directly mechanically and electrically connected to a connector of the harness assembly. The connecting end may be folded, shaped, slit-rearranged, and the like to reduce its width-to-thickness ratio, which may be close to 1.
Abstract:
In accordance with an embodiment, a multi-layered flexible printed circuit (FPC) is disclosed that includes two or more insulating layers to route conductive traces carrying radio frequency (RF) signals, e.g., data signals, and conductive traces carrying direct current (DC) signals, e.g., power signals and low-frequency control signals, while sufficiently isolating the RF signals from electrical interference by the DC transmission lines. This advantageously eliminates having two or more separate FPCs to electrically couple each optical subassembly, e.g., receiver optical subassemblies (ROSAs) and transmitter optical subassemblies (TOSAs), to associated circuitry in a transceiver housing, which saves space and reduces manufacturing complexity, for example.
Abstract:
Methods to systematize the development of machines using inexpensive, fast, and convenient fabrication processes are disclosed. In an embodiment, a folding pattern and corresponding circuit design can provide the blueprints for fabrication. The folding pattern may be provided (e.g. laser machined) on a flat sheet of substrate material, such as a polymer. The circuit pattern may be generated by etching or applying (e.g. sputtering) a copper foil layer onto the substrate. Circuit components and actuators may then be added at specified locations. The flat substrate may then be folded along the predefined locations to form the final machine. The machine may operate autonomously to perform a task.
