Darüber hinaus betrifft die Erfindung auch ein Verfahren zum Herstellen einer solchen Metallkernleiterplatte (1). Vorteile: Durch das Vorsehen von Biegebereichen (BB) können die elektrischen Bauelemente (10, 100) der Metallkernleiterplatte (1) in zueinander verschiedenen Ebenen angeordnet werden.
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 major components and subassemblies self-interconnect by integral guide and connection features effecting “slide lock” and “snap lock” self-interconnection. The major components and subassemblies self-ground by establishing an interference fit with exposed, resilient, embossed portions of wire mesh.
Abstract:
The present invention relates to an optoelectronic interconnection module for use in optical communications and comprising a substrate (10) having a main portion (15) and a foldable portion (20) formed on the substrate (10) for arranging an optically active device (25) therein. The foldable portion (20) is adapted to be folded with respect to the main portion (15) into a desired optical coupling orientation for which an optical operative axis (OA) of the optically active device (25) arranged therein is substantially aligned with an optical transmission axis (TT') that is not perpendicular to the main portion (15). An holding fixture (70) is provided for holding the foldable portion (20) in a desired optical coupling orientation with respect to the main portion (15).

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.

The lighting device comprises a stack of functional layers that in turn comprise at least: an optics layer comprising at least one optical element; a light source layer comprising at least one light source that is adapted to radiate light through the optics layer to an exterior; a printed circuit board connected to an electronic driver to drive the lighting device; and a cooling layer comprising at least one cooling element for cooling at least the at least one light source.
Abstract:
Es wird eine Leiterplatte vorgeschlagen, die zusätzlich zu anderen Bauteilen oder ohne weitere Bauteile einen abgegrenzten und/oder definierten Sensorbereich aufweist, der zwar mit dem Rest der Leiterplatte verbunden ist, von dieser aber derart getrennt ist, dass er unabhängig von dem Rest der Leiterplatte mechanisch verformbar ist. Zur Messung des Grades der Verformung sind elektrische Bauteile vorgesehen, nämlich beispielsweise mindestens ein Widerstand, der mit dem Sensorbereich derart verbunden ist, dass er sich mit diesem zusammen mechanisch verformt. Der Widerstand besteht aus einem Material, dessen Widerstandswert von dem Grad seiner Verformung abhängig ist. Zur Messung dieses sich ändernden Widerstandswerts dient eine elektronische Schaltung, insbesondere eine Wheatstonebrücke. Der Widerstand wird in Dickschichttechnologie auf den sich verformenden Sensorbereich aufgedruckt. Es können Messmodule vorhanden sein, die mit der Leiterplatte definiert verbunden werden und die auf den Sensorbereich mechanisch einwirken. Auf diese Weise wird die Leiterplatte selbst Teil eines Sensors.
