Abstract:
A thermal management system for an electrical component includes a printed circuit board (PCB) capable of receiving the electrical component on a first side of the PCB. An elongate member has one end attached to a second side of the PCB, and another end disposed away from the PCB. The elongate member also has an open interior that facilitates fluid communication between the two ends. One of the ends defines an at least partially closed boundary on the PCB. The PCB includes an aperture disposed therethrough proximate the boundary such that fluid communication is facilitated between the first side of the PCB and the second side of the PCB, and along at least a portion of the elongate member.

Abstract:
Convertisseur de puissance de courant continue en courant alternatif, ledit convertisseur comprenant une carte électronique de puissance réalisée sur un substrat métallique isolé (11) comprenant : - un support métallique (43) formant face arrière dudit substrat métallique isolé (11), et - une couche d'isolant (42) recouvrant le support métallique, formant face avant dudit substrat métallique isolé (11), le convertisseur comprenant en outre au moins un composant (30) monté sur la face arrière du substrat métallique isolé (11), ledit composant (30) comprenant au moins une fiche (32) qui traverse le substrat métallique isolé (11) par l'intermédiaire d'un trou débouchant (46) dans ledit substrat métallique isolé (11), et ledit composant (30) étant soudé à au moins une piste de liaison électrique (41) au moyen d'une pièce intermédiaire (70) placée en face avant dudit substrat métallique isolé (11) et permettant de faire l'interface entre ladite au moins une piste de liaison électrique et la fiche du composant (30).
Abstract:
Multiple small conductive and flexible hollow rings (10), each of which is made from a pliable material, provide a flexible connection medium for use between a substrate (8) and a microelectronic device package (4). Each ring is soldered to both the substrate and the device. A portion (20, 22) of the sidewall of each ring is not soldered thus insuring that at least part of the ring stays flexible. The rings accommodate elevation differences on a substrate and electronic device package. They also provide a vibration resistant and flexible joint.
Abstract:
A stress relaxation electronic part to be mounted on a wiring board and having a conductive stress relaxing mechanism body on the side where the part is connected to the wiring board.
Abstract:
A display apparatus including a waveguide is provided. The display apparatus includes a display panel; a backlight configured to provide light to the display panel; a heat sink configured to absorb heat generated by the backlight; a bottom chassis configured to support the backlight and the heat sink; a first circuit board mounted on the bottom chassis; a second circuit board mounted on the bottom chassis; and a waveguide formed between the first circuit board and the second circuit board.
Abstract:
Connecting a capacitive measuring probe at elevated temperatures is achieved by direct attachment of metallic connecting components on a temperature substrate. A method and apparatus for a high temperature cable to circuit board connection involves a set or plurality of connecting elements that are soldered directly on the circuit board and a set or plurality of mating connecting elements that are soldered to a secondary circuit board having soldering pads for a cable.
