Abstract:
A fingerprint module includes a cover plate, a fingerprint chip, an intermediate board, and a circuit board. An assembling region is disposed on the cover plate. The fingerprint chip is fixed in the assembling region. The intermediate board is bonded to one surface of the fingerprint chip opposite to the cover plate to press the fingerprint chip. The circuit board is electrically connected to the fingerprint chip via the intermediate board.
Abstract:
[Problem] To solve a deformation and a position aberration of the multipolar lead parts used in a connection with a board. [Means for solving the problem] The present invention is multipolar lead parts having plural leads and a retaining member, wherein the retaining member includes a cylindrical portion so as to cover peripheries of the leads, the cylindrical portion facing in a board direction; wherein the leads each include an upper-side board coupling portion and a lower-side board coupling portion; wherein the lower-side board coupling portion comprises a forward protruding portion that the other end side of each of the leads is bent in a direction orthogonal to an arrangement face of the leads, a vertical portion extending downward from a front end, a solder coupling portion extending backward from a lower end, and a rising portion extending upward from the solder coupling portion; and wherein a bending angle of the rising portion with respect to the solder coupling portion is formed so as to be substantially identical to a bending angle of the vertical portion with respect to the solder coupling portion.
Abstract:
A wiring board includes an insulating substrate (1) composed of a ceramic sintered compact; and a connection pad (2) disposed on a surface part of the insulating substrate. The connection pad includes a first portion (2a) disposed on the surface part of the insulating substrate and a second portion (2b) disposed on the first portion and an outer periphery of the second portion being located on an inner side of an outer periphery of the first portion. The second portion (2b) of the connection pad is composed of platinum, and at least an exposed surface part of the first portion (2a) of the connection pad is composed of platinum containing a ceramic component. Since a brazing material used when a lead terminal is joined to the connection pad does not readily flow onto the second portion (2b), an outer periphery of the brazing material and the outer periphery of the connection pad are located at different positions, and fracture in the connection pad caused by thermal stress concentration on the outer periphery of the connection pad, or the like is suppressed. Further, an exposed surface of the connection pad is composed of platinum or platinum containing a ceramic component, and therefore does not readily oxidize. Thereby, an excellent heat-resistant wiring board or the like can be obtained.
Abstract:
Die vorliegende Erfindung betrifft einen Umrichter (1), insbesondere mehrphasiger Drehstromumrichter, mit einem mindestens einen Leistungshalbleiter (7) aufweisenden Leistungsmodul (3) und einem Kühlkörper (21), wobei das Leistungsmodul (3) von einer Leiterplatte (6) gebildet sind, die mit einer den Leistungshalbleitern (7) gegenüberliegenden Seite an einem Kühlkörper (21) anliegt und mittels mindestens eines Befestigungsmittels (20a; 20b), insbesondere einer Verschraubung, mit dem Kühlkörper (21) in thermischen Kontakt bringbar und an dem Kühlkörper (21) befestigt ist. Zur Lösung der Aufgabe, einen derartigen Umrichter zur Verfügung zu stellen, bei dem mit geringem Bauaufwand ein vollflächiges Anliegen der Leiterplatte an dem Kühlkörper erzielt werden kann und ein verbesserter thermischer Kontakt der Leiterplatte mit dem Kühlkörper erzielbar ist, wird erfindungsgemäß vorgeschlagen, dass zur zusätzlichen Anpressung der Leiterplatte (6) an dem Kühlkörper (21) ein Druckrahmen (25) vorgesehen ist. Der Druckrahmen (25) steht gemäß einer bevorzugten Ausführungsform der Erfindung mit dem Umfang der Leiterplatte (6) in Wirkverbindung.
