Abstract:
Apparatus may be provided including a high power light emitting diode (LED) unit, at least one printed circuit board, and an interfacing portion of a heat sink structure. The high power LED unit includes at least one LED die, at least one first lead and at least one second lead, and a heat sink interface. The at least one printed circuit board includes a conductive pattern configured to connect both the at least one first lead and the at least one second lead to a current source. The interfacing portion of the heat sink structure is that portion through which a majority of heat of the heat sink interface is transmitted. The interfacing portion is directly in touching contact with a majority of a heat transfer area of the heat sink interface.
Abstract:
A substrate of the present invention is provided with a plurality of parallel-arranged functional sections. First and second connecting sections are provided on both ends of the functional sections. Every two adjacent functional sections are separable from one another and are respectively connected with different connecting sections so that the substrate can be separated into two daughter substrates having identical areas. The two daughter substrates of the substrate can be processed simultaneously before separated from each other, thus saving the processing time. When used by a user, one daughter substrate can be used independently as a light source or the two daughter substrates can be used opposite to each other so that the functional sections of the two daughter substrates are staggered.
Abstract:
An electronic device includes chassis, a first printed circuit board, a second printed circuit board and a shell. The chassis includes a locating surface on which the first printed circuit board is mounted. The second printed circuit board is substantially perpendicularly mounted on the first circuit board and electrically coupled it. The shell is positioned on the locating surface to cover and receive the first and second printed circuit boards.

Abstract:
A circuit board adapted to a fan comprises a circuit region and a heat-dissipative film. The circuit region is provided on a first surface of the circuit board and comprises at least one heat-generating component thereon. The heat-dissipative film is coated on an edge portion of the first surface and is in contact with the heat-generating component. A plurality of openings through the heat-dissipative film, a protrusion of the circuit board, a cutout in the protrusion to expose the heat-generating component to airflow, etc., have been disclosed and claimed for enhancing the efficiency in heat dissipation. A heat sink may also be provided on a second surface opposite to the first surface of the circuit board. The heat sink is connected to the heat-dissipative film to help dissipate the heat generated by the operation of the fan.
Abstract:
A component, equipped for rotational insertion into a circuit module, has at least one contact electrically coupled to a first terminus of a connecting wire. The connection wire has a second terminus electrically coupled to a counter-contact on the circuit module. The contact has an annular extension in the circumferential direction which encloses the counter-contact even when a radial center line of the contact area angular extension lies outside the counter-contact angular extension. The contact may be ring-segment shaped or ring shaped. Numerous contacts may be arranged at different radial distances from the component's axis of rotation.
Abstract:
The present invention relates to circuit boards with radially arrayed components. One specific embodiment is a memory circuit board with memory components, such as, for example, DRAM chips, radially arrayed around a central point. The present invention also relates to stacking and connecting multiple circuit boards with radially arrayed components. Another embodiment of the invention involves methods of preparing radially arrayed components on a circuit board module with substantially equidistant paths to the components.
Abstract:
