Abstract:
The invention relates to a modular microelectronic component and a method for the production thereof. The inventive method comprises the following steps: a) at least two functional layers (12, 22) are produced, each of which is provided with a planar support (10, 20), electronic components, 1 to 5, 8, 9) located on the support (10, 20), a conductor structure, and electrical first contact points (11, 21) located on the edge (6, 23) of the support (10, 20). The conductor structure contacts the electronic components at least in part while being at least partly connected to the first contact points (11, 21) on the edge (6, 23) of the support (10, 20); b) the functional layers (12, 22) are placed on top of each other layer by layer; c) the functional layers (12, 22) are electrically connected via the first contact points (11, 21). The invention makes it possible to produce an extremely compact and robust microelectronic component while the adjusting effort can be kept very low compared to other modular methods when designing the individual functional layers. Very different aspect ratios of the individual functional layers are rather unproblematic during system integration, resulting in a small amount of development effort.
Abstract:
Die Erfindung betrifft Leiterplatten, die untereinander durch flexible Leiterbahnen oder Jumper verbunden werden. Es ist wünschenswert, die Jumper in einem dem Lötprozess und in einem Schritt zusammen mit anderen SMD- und sonstigen Bauteilen auf den Leiterplatten in einem Reflow-Lötofen zu löten. Dazu sind bei der erfindungsgemäßen Leiterplatte (10), die üblicherweise mehrere Innenlagen (11) sowie innere Leiterbahnen (12) und äußere Leiterbahnen (13) aufweist, in der Stirnseite (18) seitliche Öffnungen (17) angebracht, die vorzugsweise metallisiert sind. Nach Ein- bzw. Aufbringen von Lotpaste können dort hineingesteckte Anschlußpins bzw. Anschlußdrähte (16) eines Jumpers (15) zusammen mit anderen Bauteilen auf der Leiterplatte (10) in einem Reflow-Lötofen verlötet werden.
Abstract:
Disclosed are methodologies for defining matched-impedance surface-mount technology footprints on a substrate such as a printed circuit board, for example, that is adapted to receive an electrical component having an arrangement of terminal leads. Such a footprint may include an arrangement of electrically-conductive pads (P) and an arrangement of electrically-conductive vias (V). The via arrangement may differ from the pad arrangement. The vias (V) may be arranged to increase routing density, while limiting cross-talk and providing for matched impedance between the component and the substrate. The via arrangement may be altered to achieve a desired routing density on a layer of the board. Increasing the routing density may decrease the number of board layers, which tends to decrease capacitance and thereby increase impedance. Ground vias (G) and signal vias (S) may be arranged with respect to one another in such a manner as to affect impedance. Thus, the via arrangement may be altered to achieve an impedance that matches the impedance of the component. The via arrangement may be also be altered to limit cross-talk among neighboring signal conductors. Thus, the via arrangement may be defined to balance the impedance, cross-talk, and routing density requirements of the system.

A metal core printed wiring board in which a large number of lead terminal such as of an IC or an LSI are formed by etching or the like method at an edge of at least one end of a conductive substrate that serves as a core, the core and the terminals are bonded together with an insulating bonding material maintaining electrical insulation, a conductive circuit pattern is formed directly on the surface of the insulating bonding material, or a printed board on which the wiring has been printed is adhered onto the surface of the insulating bonding material, in order to increase the density of mounting, to facilitate the connection to other circuit substrates such as mother boards, and to decrease the volume of circuit.

Abstract:
A multi-layer micro-wire structure (5) includes a substrate (10) having a substrate edge (12). A first layer is formed over the substrate extending to a first layer edge (22). One or more first micro-channels (60) are imprinted in the first layer, at least one imprinted first micro- channel having a micro-wire (50) forming at least a portion of an exposed first connection pad in the first layer. A second layer (30) is formed over the first layer extending to a second layer edge (32). One or more second micro-channels (62) are imprinted in the second layer, at least one imprinted second micro-channel having a micro- wire (50) forming at least a portion of an exposed second connection pad in the second layer. The second-layer edge is farther from the substrate edge (D2) than the first-layer edge (D1) for at least a portion of the second-layer edge so that the first connection pads are exposed through the second layer.

A system (150) for transmitting or receiving signals may include a dielectric substrate (154) having a major face (166), a communication circuit (152), and an electromagnetic-energy directing assembly (178). The circuit may include a transducer (156) configured to convert between RF electrical and RF electromagnetic signals and supported in a position spaced from the major face of the substrate operatively coupled to the transducer. The directing assembly may be supported by the substrate in spaced relationship from the transducer and configured to direct EM energy in a region including the transducer and along a line extending away from the transducer and transverse to a plane of the major face.
