Abstract:
Embodiments of the present invention disclose a PCBA chip package component and a soldering component, which can facilitate repairing of a PCBA chip package module. The PCBA chip package component in the embodiments of the present invention includes: a module board and an interface board. A first soldering pad is set on the bottom of the module board, a second soldering pad is set on top of the interface board, and the second soldering pad is of a castle-type structure. The first soldering pad includes a first soldering area, a second soldering area, and a connection bridge that connects the first soldering area and the second soldering area. The first soldering area corresponds to a top surface of the second soldering pad, and when the first soldering area is soldered to second soldering pad, the second soldering area is located outside the second soldering pad. The embodiments of the present invention further provides a soldering component. The embodiments of the present invention may facilitate the repairing of the PCBA chip package component.

Abstract:
A control board (10) has a pattern for a low-voltage circuit including a ground pattern connectable to a ground and a pattern for a high-voltage circuit including a ground pattern. The patterns for the low-voltage and high-voltage circuits each have one or more ground-connection lands (13a, 13b) configured to connect the ground patterns thereof to each other via one or more capacitors.
Abstract:
The present invention provides a circuit board connecting structure enabled to obtain the reliable connection between circuit patterns by restricting the elongation of a flexible base material even when connecting portions are arranged in a face-to-face configuration and are press-contacted with each other. A circuit board connecting structure 10 includes a first circuit board 11, and a second circuit board 12. The circuit board connecting structure 10 is configured so that when a first connecting portion 13 and a second connecting portion 14 are sandwiched by a pair of pressing jigs 18, 19 and are press-contacted with each other, one 23 of first outer dummy terminals is accommodated between columns of ones 33, 33 of second outer dummy terminals, while the other first outer dummy terminal 24 is accommodated between columns of the other ones 34, 34 of the second outer dummy terminals.
Abstract:
Die Erfindung betrifft eine elektronische Schaltung mit mindestens einer ersten leitenden Fläche (3, 5), die im wesentlichen ein einziges Potential aufweist und wenigstens teilweise um eine zweite leitende Fläche (6), die im wesentlichen das gleiche elektrische Potential wie die erste leitende Fläche aufweist, herum angebracht ist. Um in solchen Schaltungen elektromagnetische Störungen wirksam reduzieren zu können und gleichzeitig beim Design der Schaltungen mehr Freiheit bei der Positionierung der Bauteile zu haben wird vorgeschlagen, die erste leitende Fläche (3, 5) an mindestens einer ersten Trennstelle (7, 8) einzuschneiden und/oder aufzutrennen und die sich dadurch ergebenden Enden der ersten leitenden Fläche (3, 5) mit einer reellen Impedanz (11), welche die innerhalb der ersten leitenden Fläche (3, 5) vagabundierende HF-Energie in Wärme umwandelt, zu verbinden. Außerdem betrifft die Erfindung ein Verfahren zur Reduzierung von EMV-Störungen in einer solchen Schaltung.
Abstract:
La présente invention se rapporte à une carte électronique, qui comporte des composants électroniques reliés par au moins une piste conductrice (10), ainsi qu'au moins une zone de contactage (4) également conductrice et connectée à ladite piste (10) Selon l'invention, ladite zone de contactage (4) présente un tracé sinueux, avec au moins deux parties en regard (41, 42 ; 43, 44) séparées par un intervalle (1 1 ) dont la largeur est inférieure à la plus petite largeur d'une pointe (1 2 ) de contactage sur ladite carte, de sorte que, quel que soit le point d'impact de ladite pointe (3) sur ladite zone, cette pointe soit en contact avec une partie (41 ; 42 ; 43 ; 44), voire deux parties en regard (41, 42 ; 43, 44) dudit tracé.
