Abstract:
This improved surface mount power supply can withstand the rigors of the manufacturing process and still create sturdy and robust connection to a user's circuit card. The open frame power module uses a U-shaped or T-shaped interconnect rather than a spherical interconnect. In one embodiment, the U-shaped interconnect can have a hole through one surface to allow the wicking of solder. The wicked solder provides a sturdier connection that is more likely to survive subsequent reflow processes. The power module is also built on a thicker FR4 board. The thicker board is less likely to warp during subsequent heating.
Abstract:
Disclosed is a bump structure, which has a hollow body, for electrically connecting a first member and a second member. Also disclosed is a method for making a bump structure, which has the steps of: preparing a molding plate with a concave mold to mold a bump-forming member; forming a conductive thin film so as to form a predetermined cavity in the concave mold of the molding plate; preparing a substrate to which the conductive thin film is to be transferred; and transferring the conductive thin film formed on the molding plate to the substrate.
Abstract:
A resilient electrical connector assembly (100) includes a base PCB and stacked layers of interconnected resilient conductive structures where each structure has at least two resilient conductive strips (115, 130, 145) and at least two conductive contacts (105, 110, 135, 140, 150, 155, 160, 165). One contact is integrated with a conductive path on the base PCB (105, 110) and another contact pad (160, 165) is positioned to establish a conductive path with a target PCB when the latter is mounted parallel to the base PCB. The resilient conductive strips flex due to a compressive force exerted between the base PCB and target PCB on the stacked layers. The resilient conductive structures are formed by depositing metal to sequentially form each of the stacked layers with one contact being initially formed in engagement with the conductive path on the base PCB.
Abstract:
An assembly (1) is disclosed, comprising at least one electrical device (5) and at least one carrier substrate (2) arranged to support the at least one electrical device (5). The at least one carrier substrate (2) is arranged with at least one tubular structure (6), which is at least in part hollow and arranged so as to permit passage of fluid through the at least one carrier substrate (2), for example between a first side (3) of the carrier substrate (2) and a second side (4) of the carrier substrate (2), and wherein the at least one tubular structure (6) is arranged such that it has an extension so that it protrudes a predefined distance from at least one of the first side (3) and the second side (4). A lighting device comprising the assembly (1) and a method (30) for manufacturing the assembly (1) are also disclosed.
Abstract:
Die Erfindung bezieht sich auf eine drahtbeschriebene Leiterplatte oder Platine mit sich auf und/oder in der Leiterplatte oder Platine zwischen Anschlussstellen erstreckenden Leitungsdrähten. Um derartige Leiterplatten zu verbessern, ist erfindungsgemäß vorgesehen, dass zumindest einer der Leitungsdrähte einen rechteckförmigen oder quadratischen Querschnitt aufweist .
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.
