Method for laying a wire conductor (3) on a substrate (2) by means of a wire laying pin (10), which embeds the wire conductor (3) under the influence of ultrasound into the surface of the substrate (2), and for the electrically conductive connection of the wire conductor (3) to a contact surface (7,8) of a chip (4), which is attached to the substrate, by means of a welding die (11), wherein the wire laying pin (10), subsequent to an attachment of the wire conductor (3) to the substrate (2), is lifted off the substrate (2) and then moved into a position starting from which the wire conductor (3) forms a straight wire line (15) extending in the air space above the substrate (2) and extending from the mouth of the wire laying pin (10) to an attachment point (F) at which the wire conductor (3) is attached to the substrate (2) or embedded into the substrate(2), whereupon the welding die (11) grips the wire in the area between the wire laying pin (10) and the end point (14) of the wire laying cycle, brings it up to the contact surface (7,8) of the chip (4) associated therewith, and welds it to the contact surface or whereupon a wire gripper (12) grips the wire conductor (3) in the area between the wire laying pin (10) and the attachment point (F), the wire gripper (12) and preferably also the wire laying pin (10) are then moved in such a way that the wire conductor (3) spanned in between them from now on traverses the contact surface (7,8) of the chip (4) associated therewith, finally the welding die (11) presses the wire conductor (3) spanned in between the wire gripper (12) and the wire laying pin (10) onto the contact surface (7,8) and welds it to the contact surface.
摘要:
Es wird ein Verfahren zum gleichzeitigen mechanischen und elektrischen Verbinden von zwei einander nur teilweise überdeckenden, mit elektrisch leitenden Strukturen versehenen Teilen (2, 4) angegeben. Zumindest einer der Leiter ist zur elektrischen Isolierung und/oder zum mechanischen und/oder chemischen Schutz über den Überdeckungsbereich hinaus großflächig unter Einschluss der Verbindungsfläche mit einem elektrisch isolierenden Material (1) bedeckt. Zur Herstellung der Verbindung werden die leitenden Teile im Bereich ihrer Verbindungsflächen sowie im diese umgebenden Bereich gegeneinander gepresst. Als elektrisch isolierendes Material wird ein Klebstoff verwendet, der während des Verbindens unter Ausbildung eines elektrischen Kontakts (6) zwischen den elektrischen Verbindungsflächen und im diese umgebenden Bereich in einen klebrigen Zustand versetzt und anschließend in einen dauerhaft haftenden Zustand übergeführt wird.

Devices and methods for electrical interconnection for microelectronic circuits are disclosed. One method of electrical interconnection (90) includes forming (92) a bundle of microfilaments, wherein at least two of the microfilaments include electrically conductive portions extending along their lengths. The method can also include bonding (94) the microfilaments to corresponding bond pads of a microelectronic circuit substrate to form electrical connections between the electrically conductive portions and the corresponding bond pads. One microelectronic circuit (10) can include a bundle (16) of microfilaments (18) bonded to corresponding bond pads (14) to make electrical connection between corresponding bonds pads and electrically-conductive portions of the microfilaments.

Exterior lighting assemblies for use on vehicles include a flexible substrate on which are mounted a plurality of solid-state light emitting devices (34) that are preferably light emitting diodes (LEDs), although other types of devices can alternatively be employed. The light emitting devices are connected to flexible conductive traces on the flexible substrate, and leads connect the traces to a power supply on the vehicle so that electrical current can be selectively supplied to energize the light emitting devices. The flexible substrate is adapted to be mounted on the exterior surface of a vehicle, for example, as a tail lamp assembly (30), or as a headlamp, and to conform around a curved exterior surface (22). Devices that emit differently colored light can be used for indicating braking, turn direction, or to illuminate a surface over which the vehicle is travelling. A flexible optically transparent cover protects the light emitting devices.
