Abstract:
Die Erfindung beschreibt eine Anordnung in Druckkontaktierung für äußerst kompakte Leistungshalbleitermodule. Diese besteht aus einer Leiterplatte (100), einem Leistungshalbleitermodul (200) und einer Kühleinrichtung (300b). Das Leistungshalbleitermodul weist ein rahmenartiges isolierendes Kunststoffgehäuse (210) sowie einen Deckel (212) mit Ausnehmungen auf. Die zweite Deckfläche des Gehäuses wird von einem Substrat (230) mit mindesten einer Leiterbahn und mindestens einem hierauf angeordneten und schaltungsgerecht verbundenen Leistungshalbleiterbauelement (240) gebildet. Kontaktfedern (250), die durch die Ausnehmungen des Deckels hindurchreichen verbinden das Substrat mit der Leiterplatte. Das Gehäuse des Leistungshalbleitermoduls weist in Richtung der Leiterplatte und/oder in Richtung der Kühleinrichtung Fortsätze (330b,330c) auf, die durch Ausnehmungen dieser hindurchragen und die entweder eine reversible oder eine irreversible Verbindung mit der Leiterplatte und/oder der Kühleinrichtung darstellen.
Abstract:
A method for adapting an electronic component in which the connectors are not adapted to surface mounting on an electric circuit. The method comprises a step of folding said connectors. The folding step complies the connectors of said component so that they are adapted to be mounted on the surface of the electrical circuit. The invention particularly relates to electronic components such as radio frequency and hyper frequency power transistors available on the market in a straight-connector version.

Abstract:
Products and assemblies are provided for socketably receiving elongate interconnection elements, such as spring contact elements, extending from electronic components, such as semiconductor devices. Socket substrates are provided with capture pads for receiving ends of elongate interconnection elements extending from electronic components. Various capture pad configurations are disclosed. A securing device such as a housing positions the electronic component securely to the socket substrate. Connections to external devices are provided via conductive traces adjacent the surface of the socket substrate. The socket substrate may be supported by a support substrate. In a particularly preferred embodiment the capture pads are formed directly on a primary substrate such as a printed circuit board.
