Abstract:
A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting “slide lock” and “snap lock” self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.

A design support method includes: selecting, by a computer, a power feed point of an integrated semiconductor circuit on a first board model in which a power supply layer and a ground layer are stacked; determining a first placement position of a first protrusion portion from the first board model on a side of the first board model, the first protrusion portion being corresponding to the power feed point; determining a second placement position of a second protrusion portion from the first board model on the side of the first board model, the second protrusion portion provided so as to separate from the first placement position by a distance; and placing the first protrusion portion and the second protrusion portion on the first placement position and the second placement position, respectively.
Abstract:
A suspension board with circuit includes a conductive pattern. The conductive pattern includes a first terminal provided on the front face of the suspension board with circuit and electrically connected with a magnetic head; and a second terminal provided on the back face of the suspension board with circuit and electrically connected with an electronic device.
Abstract:
An electrical circuitry has a base element, a printed circuit board and a fastening apparatus for fastening the printed circuit board to the base element. The fastening apparatus retains the printed circuit board by virtue of the base element being present on a top side and underside of the printed circuit board. In this case, the base element acts upon the top side and underside of the printed circuit board at application points which are opposite one another at an offset with respect to one another while elastically deforming the printed circuit board.
Abstract:
A suspension board with circuit includes a gimbal portion. The gimbal portion includes a tongue portion formed at the inner side of the opening for being mounted with a slider mounted with a magnetic head for being electrically connected to the conductive layer, an outrigger portion formed at the outer side of the opening to support the tongue portion, and a passing portion passing through the opening of the gimbal portion and/or an outer side region of the outrigger portion. The passing portion includes the conductive layer and the insulating layer covering the conductive layer. The thickness of a lower half portion of the insulating layer in the passing portion is the same as that of an upper half portion thereof.
Abstract:
An assembly of a plurality of tiles (1) with a carrier (40), wherein the tiles (1) comprise a foil (20) with an electro-physical transducer (10) and electrical connectors (24, 28) to said transducer. The tiles are mechanically and electrically coupled to the carrier, and the tiles overlay according to a fish scale pattern.
Abstract:
A head gimbal assembly for a hard disk drive includes a head slider having a head element part which performs reading and/or writing of data to/from a magnetic disc and a suspension on which the head slider is mounted. Bonding pads formed on the head slider are formed on a side surface of the head slider except for an air bearing surface (ABS) which faces the magnetic disc and a back surface on a side opposite to the ABS. End peripheries of the bonding pads are arranged to be in contact with an end periphery of the side surface of the head slider which abuts on the back surface of the head slider.
Abstract:
An interconnecting structure for interconnecting two electronic modules. The structure includes a dielectric substrate having a copper trace deposited on the lower surface thereof, and a copper pad disposed on the upper surface of the substrate directly above one end of the trace. A first copper plate-up area deposited on the pad, and a second copper plate-up area is deposited on the distal end of the trace. A slot, semi-circumscribing the pad and extending on both sides of the trace toward the distal end of the trace, is cut through the substrate to allow the proximal end of the trace to be displaced in a cantilevered manner below the lower side of the substrate when a force is applied to the pad.
Abstract:
Embodiments relate to coupling and/or holding devices for electrically and/or mechanically contacting circuit elements, such as power sources, sensors, transducers and other devices. In one embodiment, a coupling device comprises a substrate having at least one printed conductive element and at least one fold, flap, slit, slot, perforation or other alteration configured to encourage contact between a circuit element, such as a battery, sensor, transducer or other element, and the at least one printed conductive element.
Abstract:
Provided are an opto-electric hybrid board and a manufacturing method. The opto-electric hybrid board includes an optical waveguide unit and an electric circuit unit having an optical element mounted thereon. The optical waveguide unit includes socket portions for locating the electric circuit unit, which are formed on a surface of an undercladding layer and formed of the same material as a core. The socket portions are located at predetermined locations with respect to one end surface of a core. The electric circuit unit includes bent portions which are formed by bending a part of an electric circuit board so as to stand, for fitting into the socket portions. The bent portions are located at predetermined locations with respect to the optical element. The optical waveguide unit and the electric circuit unit are coupled in a state in which the bent portions fit into the socket portions.
