Abstract:
Two flat packages (110,111) are arranged to achieve a mirrored footprint when mounted or opposite sides of a printed circuit board by employing guides (100), which are positioned within a mounting aperture the printed circuit board. The flat packages include leads (120,121) which end from the edge of the flat package. A semiconductor chip is encapsulated by the flat packages.

Ein zweipoliges SMT-Miniaturgehäuse in Leadframetechnik für Halbleiterbauelemente, bei dem ein Halbleiterchip (1) auf ein Leadframeteil montiert und mit einem weiteren Leadframeteil kontaktiert ist, die als Lötanschlüsse (3) aus einem Gehäuse (2) herausgeführt sind, in das der Chip (1) eingekapselt ist, soll ohne einen Trimm- und Formprozeß rationell herstellbar, zuverlässig dicht und weiter miniaturisierbar sein. Die Lötanschlüsse (3) sind als Stanzteile des Leadframes von gegenüberliegenden Gehäuseseitenwänden seitlich abstehend mindestens bis zum die Bauelementmontagefläche bildenden Gehäuseboden geführt, wobei die Chipmontagefläche und die Bauelementmontagefläche einen rechten Winkel zueinander bilden.
Abstract:
A semiconductor device includes vertical placement part (12a, 12b, 12c, 12d) for mounting the semiconductor device on a surface of a circuit board (11) in a vertical position, and a connection part (14) for making electrical connections between the circuit board (11) and a semiconductor element (13). A stage (15) is provided on which the semiconductor element (13) is placed. The stage has supporting members causing the semiconductor device to vertically stand on the circuit board. Wiring boards (17, 18), stacked on a side of the stage (15) on which the semiconductor element (13) is placed, have windows (22) in which the semiconductor element (13) is located. The vertical placement part (12a, 12b, 12c, 12d) includes wiring lines extending between edges of the circuit boards facing the circuit board and peripheries of the windows. The wiring lines have ends located in the vicinity of the edges of the circuit boards and have a shape enabling the semiconductor device to be mounted on the circuit board.
Abstract:
A semiconductor package (30) comprises leads (34) which protrude from the bottom of a package body (32), and supports (36) which are formed at both ends of the package body (32) to mount the package on a printed circuit board (PCB). The supports (36) are made of the same material as the package body (32). In the package body (32), a slot (38) is formed to receive the leads (34). The supports (36) are staggered to mount the packages close to each other. Thus, there is no additional process step for forming holes in the PCB to mount the supports of the semiconductor package, and the mounting process of the package becomes simpler. The supports (36) protruding from the package body mount the package on the PCB firmly. The slot (38) receives the leads and protect the leads from being deformed by external forces, thereby improving the reliability of the semiconductor package.

Es soll eine einfache automatisierbare und wärmestabile Halbleiterkontaktierung für lineare und flächige SMD-Bauteile, insbesondere LED-Anordnungen verwirklicht werden. Hierzu werden auf eine mit Leiterbahnen beschichtete Trägerfolie SMD-Bauteile aufgesetzt, wobei die Leiterbahnen zur einfacheren Kontaktierung durch Aufschmelzen entweder ganz oder teilweise aus lötbarem Material bestehen.
Abstract:
A cavity is formed in a support structure, the support structure being operable to support a semiconductor device, and at least a portion of a circuit element is disposed within the cavity in the support structure. The cavity in the support structure is filled with an electrically non- conductive filling material so as to at least partially surround the circuit element with the non- conductive filling material, and the semiconductor device is electrically connected to the circuit element. In an example embodiment, the circuit element is operable to substantially block direct current that is output by the semiconductor device or another semiconductor device.

A lead component holder (10) includes a plurality of supporting portions (30a, 30b, 30c) each supporting one of lead components (C) at a position distant from a component mounting surface of a substrate (22), and at least one of coupling members (32a, 32b) respectively coupling the adjacent supporting portions (30a, 30b) and (30b, 30c) at a position distant from the component mounting surface. An electronic device (12) includes the substrate (22), the lead component holder (10), and an electronic component mounted to the substrate (22) located below the coupling members (32a, 32b).
Abstract:
A circuit protection device (31) suitable for surface mounting on a substrate (19). The device has a laminar PTC resistive element (3) which is composed of a conductive polymer composition and is positioned between first and second electrodes (5, 7). Attached to the first electrode is a first electrical terminal (33) containing an electrically conductive material which has a first attachment portion (35) connected to a first flexible portion (39) by means of a first connection portion (47). At least part of the first flexible portion is free of attachment to the first electrode. The first attachment portion is coplanar with at least one of the first connection portion and the first flexible portion, The first attachment portion may contain a slot (49) and a solid hinge portion (51). When the device is mounted on a substrate by means of a mounting component (41) extending from the first terminal, the first flexible portion allows contraction and expansion of the conductive polymer despite the rigid attachment of the mounting component onto the substrate.
