The invention also provides a method of manufacturing multi-layer interconnection devices (19).
Abstract:
Das isolierte Metallsubstrat (1) besteht aus einem mit mehreren Vertiefungen (121, 121') versehenen Metallsubstrat (12), an dessen Oberseite (12A) eine Isolationsschicht (11) mit elektrischen Bahnen (10) angeordnet ist, an die mehrere gegebenenfalls in Chip-Form vorliegende, innerhalb der Vertiefungen (121, 121') angeordnete Leuchtdioden (2) angeschlossen sind. Erfindungsgemäss sind die als Reflektor (5) dienenden, gegebenenfalls beschichteten Vertiefungen (121, 121') derart an der Oberseite (12A) in das Metallsubstrat (12) eingearbeitet, dass dessen Unterseite (12B) eine ebene Fläche bildet, die mit wenigstens einem Metallelement (120) verbunden oder verbindbar ist, das die von den Leuchtdioden (2) abgegebene und durch das Metallsubstrat (12) transferierte Wärmeenergie absorbiert.
Abstract:
Bei dem Verfahren zum Herstellen des Formbauteils (2A-2G) mit einer integrierten Leiterbahn (10) wird auf einem Trägerbauteil (4) insbesondere mit Hilfe des Flammspritzens oder des Kaltgasspritzens eine Leiterbahn (10) erzeugt. Hierzu wird die Oberfläche des Trägerbauteils (4) selektiv entsprechend einem vorgesehenen Verlauf der Leiterbahn (10) behandelt, so dass die Oberfläche Bereiche unterschiedlicher Haftung aufweist. Im vorgesehen Verlauf der Leiterbahn (10) wird eine Keimschicht (26) aufgetragen, auf diese dann wiederum die eigentliche Leiterbahn (10) aufgebracht wird. Dadurch ist ein sehr flexibles und kostengünstiges Herstellen eines Formbauteils (2A-2G) mit einem integriertem Leiterbahnmuster möglich. Insbesondere im Kraftfahrzeug-Bereich können spezielle Kundenwünsche zeitnah und problemlos durch ein geändertes Leiterbahnlayout verwirklicht werden.
Abstract:
Disclosed is a parallel processor packaging structure and a method for manufacturing the structure. The individual logic and memory elements are on printed circuit cards. These printed circuit boards and cards are, in turn, mounted on or connected to circuitized flexible substrates extending outwardly from a laminate of the circuitized, flexible substrates. Intercommunication is provided through a switch structure that is implemented in the laminate. The printed circuit cards are mounted on or connected to a plurality of circuitized flexible substrates, with one printed circuit card at each end of the circuitized flexible circuit. The circuitized flexible substrates connect the separate printed circuit boards and cards through the central laminate portion. This laminate portion provides XY plane and Z-axis interconnection for inter-processor, inter-memory, inter-processor/memory element, and processor to memory bussing interconnection, and communication. The planar circuitization, as data lines, address lines, and control lines of a logic chip or a memory chip are on the individual printed circuit boards and cards, which are connected through the circuitized flex, and communicate with other layers of flex through Z-axis circuitization (vias and through holes) in the laminate.

Abstract:
Une couche de dilatation (18) relativement mince est disposée par-dessus la carte de circuits imprimés classique (20). Cette couche de dilatation (18) est liée à la carte de circuits imprimés (20) sauf aux endroits (40) situés au-dessous de la place occupée par le support intermédiaire (13) et les brasures (42). Cette couche de dilatation permet une dilatation tolérable entre le support intermédiaire en céramique plat (13) et la carte de circuits imprimés (20) par suite de la différence de dilatation thermique, pour ainsi réduire le fissurage des brasures (42). Dans une variante d'exécution, une mince couche de polytétrafluoroéthylène (PTFE) (39) empêche la liaison au-dessous de la place occupée par le support intermédiaire. Sont également décrits des procédés d'application de cette couche de PTFE.
