Abstract:
The invention concerns an arrangement for forming discrete soldering joints in which connection sections (26) of contact elements (14) are shaped to form loops (27) or eyes (28) and each contain a solder deposit (31). The connection sections (26) are pressed in a force-locking manner by spring elements (33) onto associated insular connection surfaces (32). Owing to the supply of heat, which melts solder (29) in the solder deposit (31), the solder passes directly to the connection surfaces (32) whilst continuing to wet the connection sections (26) and forming discrete soldering joints (34). The arrangement is preferably intended for use with electric circuits in motor vehicles.
Abstract:
The present invention aims to supply an electronic component which is manufactured in a manufacturing process at low cost, and realize improvement of shock resistance, endurance, flexure resistance, mounting reliability etc. at the same time, without requiring fine adjustment etc. The invention is an electronic component 1 which has an element 2, a pair of terminal portions 4 which were disposed on the element 2, and an external covering material 5 which covers the a part of the terminal portions 4 and the element 2, and configured in such a manner that inclined portions 10 are disposed on corner portions of a bottom surface 9 and side surfaces of the external covering material 5, and the terminal portions 4 are protruded from corner portions where the inclined portions 10 and the bottom surface 9 of the external covering material intersect.
Abstract:
An improved passive electronic stacked component is described. The component has a stack of individual electronic capacitors and a first lead attached to a first side of the stack. A second lead is attached to a second side of the stack. A foot is attached to the first lead and extends inward towards the second lead. A stability pin is attached to one of the foot or the first lead.
Abstract:
Die Erfindung betrifft ein Bauelement (1), das mit einer Leiterplatte (3) verbindbar ist, wobei das Bauelement (1) einen Lötfuß (5, 7, 9) aufweist, der mit einem SMT-Pad (6, 8, 10) der Leiterplatte (3) durch eine Löt-Verbindung verbindbar ist. Gemäß der Erfindung ist die Form des Lötfußes (5, 7, 9) derart an die Form des SMT-Pads (6, 8, 10) angepasst ist, dass zwischen Lötfuß (5, 7, 9) und SMT-Pad (6, 8, 10) durch die Adhäsionskräfte von verflüssigtem dazwischenliegendem Lot eine gegenseitige, zueinander ausrichtende Anziehungskraft erzeugt wird. Beispielsweise können der Lötfuß (5, 7, 9) und das SMT-Pad (6, 8, 10) deckungsgleiche Konturen aufweisen. Die Erfindung betrifft außerdem eine Leiterplatte (3) mit einem in der beschriebenen Weise an einen Lötfuß (5, 7, 9) eines Bauelements (1) angepassten SMT-Pad (6, 8, 10). Die Er-findung ermöglicht die automatische, exakte Positionierung des Bauelements (1) auf der Leiterplatte (3) im Lötverfahren ohne zusätzliche Positionierhilfe.
Abstract:
A component carrier for an electronic component, said component carrier being made in one piece of a metal sheet material and provided with means for surface mounting on a printed circuit board (PCB) and with holding flanges (2a, 2b) for holding an electronic component. The component carrier has a base (1) provided with a central soldering platform for surface mounting on the PCB. The holding flanges (2a, 2b) extend from the base (1) and are connected to the base (1) via tongues (4a-4d) of the metal sheet material, said tongues (4a-4d) extending in a plane parallel with the base (1).
Abstract:
The control device (1) is equipped with an electrical component (2) in which heat is generated. Said heat is dissipated over an elongated metal part (10) whose one face (12) is soldered to the component (2). The face (12) oriented toward the component (2) has a shape that increases the size of its surface. The shape is outwardly arched and can be provided with a ribbing.
Abstract:
A solder-bearing metallic (114), and methods of fabricating and using it, where the lead is formed with a solder-retaining portion (125) having a cross-sectional profile with undercuts, which may be in a V-shape or flat, where solder (133) surrounds said solder-retaining portion and undercuts, and extends outwardly from the lead while leaving a portion of the lead uncovered by solder to permit the lead metal to form direct contact with a susbstrate or other conductive pad.
