Abstract:
A semiconductor device comprises a semiconductor element and a support body made of a stack of ceramic layers having a recess in which electrical conductors are electrically connected with the semiconductor element, wherein at least a part of a top face of a recess side wall is covered by a resin, thereby providing a light emitting device.
Abstract:
Disclosed examples of printed circuit boards for lighting systems have identical LED landing zones printed on the board. Each zone includes at least two sets of LED contact pads. One pad set is configured to mate with contacts of an LED of a first structural type, e.g. from a first product line or manufacturer. The other pad set is configured to mate with contacts of an LED of a second type, e.g. from a different product line or manufacturer. The layout may enable an easy system re-design, e.g. to shift from one type of LED to another. Alternatively, the layout may enable one system to use LEDs of the two different types in a single LED set or array. Exemplary systems disclosed herein include an element for mixing light produced by LEDs mounted to the landing zones, such as an optical integrating cavity.
Abstract:
A printed circuit board includes a mounting hole for receiving a connector pin of either of a first SMC and a second SMC, and a signal line. The signal line is electrically connected to the mounting hole by a conductive layer arranged in and about the mounting hole.
Abstract:
An attenuator pad adapter for utilizing a replacement attenuator pad in place of another attenuator pad intended for use on a printed circuit board. The attenuator pad adapter has a body portion with a plurality of pins extending from one of its ends that correspond with pins of the originally intended attenuator pad. A slot in an opposite end is configured to detachably receive an end of the replacement attenuator pad. Openings in the slot receive pins on an end of the replacement attenuator pad. The pins of the replacement attenuator pad electrically interconnect connect with the pins extending from the body portion of the attenuator pad adapter. The pins of the replacement attenuator pad are arranged differently than the pins extending from either the body portion or the originally intended attenuator pad.
Abstract:
A 6-pin electronic package includes a first side including a pair of first outer pins and a first middle pin, and a second side including a pair of second outer pins and a second middle pin. The first outer pins and the second middle pin are operatively coupled to a first circuit to provide a first function. The second outer pins and the first middle pin are operatively coupled to a second circuit to provide a second function. The 6-pin electronic package can be replaced on a circuit substrate with a first electronic package and a second electronic package that collectively include at least six pins. The 6-pin electronic package and the first and second electronic packages can be interchangeably used on a circuit substrate of an electronic device. The circuit substrate may include any one of the 6-pin electronic package mountable to the circuit substrate, and the first and second electronic packages. The first electronic package is mountable on the circuit substrate on a same footprint as the 6-pin electronic package. The second electronic package is mountable on the circuit substrate adjacent the first electronic package such that six pins of the first and second electronic packages share the same footprint as the pins of the 6-pin electronic package.
Abstract:
An optical package structure (2) includes a cover (21) defining an aperture (212) in a top portion for transmission of optical signals, a lens part (22) secured to the cover, and a base member (23) combining with the cover to define a closed space in which to package optical components. A plurality of solder pads (2311–2314, 2391–2394, 2391′, 2392′) is provided on both a top and a bottom surfaces (2321, 2342) of the base member, and a plurality of inner conductive traces (236, 239) extends through the base member and provides an electrical connection of the solder pads on the top surface to the solder pads on the bottom surface. All the solder pads on the top surface are connected to a complementary solder pad located along a first side edge of the bottom surface, and at least one of the solder pads on the top surface is electrically connected to one of the solder pads on the bottom surface which is not located along the first side edge.
Abstract:
A memory card including a PCB assembly that is consistent with existing 13-pad MMC mechanical form factors, and a housing that is consistent with the SD mechanical form factor, thereby providing a single PCBA and housing arrangement that can be used to produce both MMC and SD memory cards. The thirteen contact pads support all MMC and SD contact pad patterns, but are modified to facilitate a write protect switch. The housing includes an enlarged window (or windows) that exposes two or more contact pads in each of the multiple rows, thereby facilitating slidable insertion of the memory card into a socket of a host system. Alignment notches are formed in the side edges of the PCB, and/or alignment pins are utilized for properly aligning the PCBA within the housing.
Abstract:
An interface device having a video BIOS component. The device includes a substrate for implementing a mother board connection and implementing a GPU (graphics processor unit) connection. A video BIOS component is mounted on the substrate for providing video BIOS functions for the computer system.
Abstract:
A control circuit board is opposed to an outer surface of a case in the form of a rectangular box, and an connector cable, which has connector terminals connectable with an external device, extends from the circuit board. The control circuit board has a plurality of first connector pads with a first property and a plurality of second connector pads with a second property different from the first property, the first and second connector pads being arranged side by side on the control circuit board. The connector cable has a proximal end portion connected to at least one type, among the first and second connector pads, and the connector terminals including a plurality of connector terminals connecting with the at least one type of connector pads to which the proximal end portion is connected.
