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.
Abstract:
The present invention relates to a coaxial cable structure for connecting to a printed circuit board, the coaxial cable structure including: a coaxial cable part having a plurality of signal lines for transmitting data between spaced-apart modules, an inner insulator covered along the outer periphery of each signal line, a shield wire covered along the outer periphery of the inner insulator for shielding the plurality of signal lines from one another, and an outer insulator covered along the outer periphery of the shield wire to form an outer layer of each signal line; a pattern part formed on one surface of the printed circuit board, and serving as a conductor adapted to abut against the signal lines exposed to the outside of the coaxial cable part for receiving data from the coaxial cable part, the pattern part having the corresponding number of signal patterns to the plurality of signal lines and a ground pattern adapted for providing ground contacts; and a soldering part adapted to directly solder each signal line and each shield wire of the coaxial cable part exposed to the outside at the end portions thereof to the pattern part of the printed circuit board.
Abstract:
A system and method are disclosed in which flex cables are affixed to PCBs, for providing high-speed signaling paths between ICs disposed upon the PCBs. The flex cables are fixably attached to the PCBs so as to substantially mimic their structural orientation. Where the configuration includes more than one PCB, the flex cables include multiple portions which are temporarily separable from one another and from the die, using flex-to-flex and flex-to-package connectors, allowing field maintenance of the configuration. By routing the high-speed signals between ICs onto the flex cable, single-layer PCBs can be used for non-critical and power delivery signals, at substantial cost savings. By disposing the flex cables onto the PCB rather than allowing the cables to float freely, the configuration is thermally managed as if the signals were on the PCB and cable routing problems are avoided.

Ein Folienaufbau (1, 2) mit elektrischer Funktionalität und externer Kontaktierung umfasst einen Bereich (10) mit einer elektrischen Übertragungsstrecke (30) und einen Kontaktierungsbereich (20) zur externen Kontaktierung der elektrischen Übertragungsstrecke (30). In dem Kontaktierungsbereich (20) des Folienaufbaus ist mindestens eine elektrisch leitfähige Schicht (100), die eine Materialmischung aus Silber und Carbon aufweist, enthalten. Die elektrisch leitfähige Schicht (100) kann sich von dem Kontaktierungsbereich (20) des Folienaufbaus in den Bereich (10) mit der elektrischen Übertragungsstrecke (30) erstrecken und die elektrische Übertragungsstrecke bilden. Die elektrisch leitfähige Schicht (100) kann in dem Kontaktierungsbereich (20) auf einer Leiterbahn (400) angeordnet sein. Die elektrisch leitfähige Schicht (100) ist aufgrund die Mischung aus Silber und Carbon mechanisch und klimatisch stabil.
Abstract:
A patch cord (100) is provided that includes a communications cable (109) that has at least first through fourth conductors (101, 102, 104, 105) and a plug (116) that is attached to the cable (109). The plug (116) includes a housing (120) that receives the cable (109), a printed circuit board (150), first through fourth plug contacts (141, 142, 144, 145), and first through fourth conductive paths (161, 162, 164, 165) that connect the first through fourth conductors (101, 102, 104, 105) to the respective first through fourth plug contacts (141, 142, 144, 145). The first and second conductors (101, 102), conductive paths (161, 162), and plug contacts (141, 142) form a first differential transmission line, and the third and fourth conductors (104, 105), conductive paths (164, 165), and plug contacts (144, 145) form a second differential transmission line. Each of the first through fourth plug contacts (141, 142, 144, 145) has a first segment that extends longitudinally along a first surface of the printed circuit board (150), and the signal current injection point into the first segment of at least some of the first through fourth plug contacts (141, 142, 144, 145) is into middle portions of their respective first segments.
