Abstract:
PROBLEM TO BE SOLVED: To provide a fastening fixture capable of preventing deterioration of substrate holding strength even if the mounting area is made smaller than conventional one, and a surface mounting component having this fastening fixture, and a mounting structure using this fastening fixture. SOLUTION: The fastening fixture 20 is a fixing fixture for connecting a connecting object on a circuit board PCB by soldering. The fastening fixture 20 comprises a fixing part 21 to be fixed on the side of the connecting object 21 and a solder connecting part 22 which extends from the fixing part 21 and soldered and connected to the surface of the circuit board. The end part of the solder connecting part 22 is folded back in U-shape toward the outside and the ridge part 22a of straight line shape contacts the surface of the circuit board PCB. Solder fillet 30 is formed integrally mutually in close contact on both sides of the ridge part 22a of the solder connecting part 22 in contact with the circuit board PCB.

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:
Das Steuergerät (20) ist mit einem elektrischen Bauelement (2) bestückt, in dem Wärme erzeugt wird. Diese wird über ein längliches Metallteil (21) abgeführt wird, dessen eine Stirnfläche (22) mit dem Bauelement (2) verlötet ist. Die dem Bauelement (2) zugewandte Stirnfläche (22) weist eine ihre Oberfläche vergrößernde Gestalt auf. Sie ist nach außen gewölbt ausgebildet und kann mit einer Riffelung versehen sein.
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 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).
