Abstract:
The invention relates to a circuit configuration comprising a supporting body (1) which supports a circuit board conductor configuration (7) and a (cased) semi-conductor component (4). Said semi-conductor component (4) is connected electrically to said circuit board conductor configuration via connector pins (5). The aim of the invention is to provide a device for monitoring the temperature of said semi-conductor component. According to the invention, a temperature sensor (6) should be provided on said supporting body, next to said semi-conductor component (4). An electrically conductive connection is formed between said temperature sensor (6) and one of the connector pins (5) of the semi-conductor component (4) by a specially shaped interconnecting circuit board conductor (8). Said supporting body also has significantly lower calorific conductability than said interconnecting circuit board conductor so that only slight thermal deviation occurs.

Abstract:
A flexible circuit board having a flexible graphite substrate is provided. The flexible circuit board includes a dielectric layer formed on the surface of the flexible graphite substrate and an electrically conductive layer formed on the surface of the dielectric. Electronic components are mounted to the flexible circuit board to form a circuit arrangement. A thermally conductive conduit can be disposed in thermal and physical contact with a surface of the electronic component and the surface of the flexible graphite substrate to. The high in-plane thermal conductivity graphite substrate provides enhanced heat transfer capability to effectively move of heat away from the electronic components for improved cooling of the heat generating electronic component and surrounding devices. A variety of LED light arrangements are formed using the flexible graphite substrate circuit board including light engines for LCD display devices.

At least one of the first semiconductor chip and the thermal management device is at least partially positioned in the first aperture.
Abstract:
A flexible circuitry is populated with integrated circuitry (ICs) disposed along one or both of its major sides. Contacts are distributed along the flexible circuitry to provide connection between the module and an application environment. A rigid substrate is configured to provide space on one side where the populated flex is disposed while in some embodiments, heat management or cooling structures are arranged on one side of the module to mitigate thermal accumulation in the module.
Abstract:
Die erfindungsgemässe elektronische Schaltungsanordnung (10) umfasst eine Wärmesenke (12) und einen an der Wärmesenke (12) flächig aufliegend thermisch gekoppelten ersten Schaltungsträger (16) zur Verdrahtung von elektronischen Bauelementen der Schaltungsanordnung. Für wenigstens ein elektronisches Bauelement (34-1) ist eine besondere Anordnung vorgesehen, die mit einer erheblich gesteigerten Wärmeableitfähigkeit für das betreffende Bauelement (34-1) einhergeht und darüber hinaus noch weitere Vorteile im Zusammenhang mit in der Praxis etwaig vorkommenden Änderungen der Bestückung und/oder der Leitungsführung bietet. Wesentlich ist hierfür die Anordnung des Bauelements (34-1) unter einem zweiten Schaltungsträger (18-1), der in einer zur Oberseite (14) der Wärmesenke (12) hin durchgehenden Aussparung (24-1) des ersten Schaltungsträgers (16) aufgenommen ist.
