Bei einer Leiterplatte (1) umfassend eine isolierende Schicht (2) und eine auf der isolierenden Schicht (2) angeordnete und zu einer Kontaktfläche (4) für eine auf die Leiterplatte (1) zu bestückende elektronische Komponente (11) strukturierte leitende Schicht (3), weist die Leiterplatte (1) im Bereich der Kontaktfläche (4) zumindest einen, die Kontaktfläche (4) und die isolierende Schicht (2) durchsetzenden Kanal (8) auf, der mit einem wärmeleitenden Material verfüllt ist. Das Verfahren zeichnet sich durch die Schritte Bereitstellen einer isolierenden Schicht (2) und einer mit der isolierenden Schicht (2) verbundenen leitenden Schicht (3), Herstellen zumindest eines die leitende (2) und die isolierende Schicht (3) durchsetzenden Kanals (8), Auskleiden des Kanals (8) mit wärmeleitfähigem Material, Strukturieren der leitenden Schicht (3) zu einer Kontaktfläche (4) für eine zu bestückende elektronische Komponente (11), Bereitstellen eines Lotdepots (9) in zumindest minimaler Überlappung mit der Kontaktfläche (4), Aufsetzen der elektronischen Komponente (11), Aufschmelzen des Lots und Abkühlen aus.
Abstract:
The present description relates to the field of fabricating microelectronic devices, wherein a microelectronic device may have a hexagonal confirmation for signal nodes and ground nodes which utilizes the cross-talk reduction by cancellation property of geometrically symmetry and orthogonality to reduce signal node to ground node ratio for increasing signaling density.
Abstract:
Space transformer connectors for coupling printed circuit boards and/or other electrical connections are disclosed. A scalar design of a multilayer space transformer connector allows for a variety of pad-array field connections. A conductive elastomer interface provides for repeated and consistent coupling and decoupling of the space transformer connector.
Abstract:
A semiconductor device is provided which comprises a substrate (501) having a plurality of bond pads (503) disposed thereon. Each bond pad has a major axis and a minor axis in a direction parallel to the substrate, and the ratio of the major axis to the minor axis increases with the distance of a bond pad from the center of the substrate.
Abstract:
An interconnection pattern design, which has an improved reliability under mechanical shock and thermal cycling loads. A semiconductor component comprises a plurality of interconnections aligned into rows and columns to form an interconnection pattern, wherein the interconnections are aligned such that the pattern has substantially rounded or chamfered corners. The present invention provides an improved interconnection life and reliability of ball grid array packages and it is easily implemented.
Abstract:
A pressure-bonded substrate bonded to an object with pressure, having a surface-side terminal electrically connected to a terminal on a counterpart terminal and a back-side terminal formed on the back obliquely with respect to the surface-side terminal. A uniform pressure is applied to the substrate-side terminal in pressure bonding, and consequently a pressure-bonded structure having a high connection reliability is stably produced.
Abstract:
A plurality of plate-like circuit component carrier packages (71) are stacked adjacent one to another with the flat faces (72, 74) thereof in contact to form a carrier package assembly (40). Each carrier package houses one or more electrical circuit component (110) coupled to electrical contacts (84, 86) on the flat faces and electrical contacts (98) or upstanding pins (424, 436) on the sides. These cooperate with those of adjacent carrier packages to electrically interconnect with the circuit components therein. A flexible, printed circuit board (50) having an array of contact sites (52) selectively interconnected by printed routing traces (54) is wrapped around the carrier package assembly. The ends of the carrier package assembly are fitted with supporting and electrically interconnecting connector blocks (22, 16). Plural carrier package assemblies are interconnectable directly, by nesting, or through intermediate connecting structures.
