Abstract:
Provided is an LED lamp using a nano-scale LED electrode assembly. The LED lamp using the nano-scale LED electrode assembly may solve limitations in which, when a nano-scale LED device according to the related art stands up and is three-dimensionally coupled to an electrode, it is difficult to allow the nano-scale LED device to stand up, and when the nano-scale LED devices are coupled to one-to-one correspond to electrodes different from each other, product quality is deteriorated. Thus, the nano-scale LED device having a nano unit may be connected to the two electrodes different from each other without causing defects, and light extraction efficiency may be improved due to the directivity of the nano-scale LED devices connected to the electrodes. Furthermore, deterioration in function of the LED lamp due to the defects of a portion of the nano-scale LEDs provided in the LED lamp may be minimized, and the LED lamp may have a flexible structure and shape by using the nano-scale LED electrode assembly of which a portion is deformable according to the used purpose or position of the LED lamp.

A light-emitting device includes a plurality of light-emitting elements mounted on a wiring board, and a plurality of wirings that are provided on the wiring board and each connect predetermined ones of the plurality of light-emitting elements in series. A central element-connection wiring has a longest wiring length among the plurality of wirings, and a voltage applied to a central element is a lowest one of voltages applied to the plurality of light-emitting elements. A closest one of the plurality of light-emitting elements to a center of an element mounting region of the wiring board is defined as the central element, and a wiring that connects in series the central element is defined as the central element-connection wiring.

Disclosed herein is a coil component that includes a drum-shaped core having a flange portion and a winding core around which a wire is wound. The flange portion includes first and second side surface opposite to each other, and a mounting surface. The mounting surface of the flange portion includes first and second convex portions and a concave portion positioned therebetween. The first convex portion has a third side surface parallel to the first side surface of the flange portion. The second convex portion has a fourth side surface parallel to the second side surface of the flange portion. A level difference between the first side surface and the third side surface is larger than a level difference between the second side surface and the fourth side surface.
Abstract:
A socket (female connector) used for a connector assembly includes a film substrate constituted by a flexible thin board made of insulation material. The film substrate is provided with connection through holes adapted to be inserted therein connection posts of a header (male connector). Connection pads are formed on a first surface of the film substrate around respective connection through holes. The connection pads include a first pad and a second pad. The film substrate is provided on the first surface with a first patterned conductor connected to the first pad and a third patterned conductor connected to the second pad. The third patterned conductor is connected to a second patterned conductor formed on a second surface of the film substrate by means of a blind via that is formed by boring the film substrate from the second surface so as to reach the third patterned conductor.
Abstract:
A flip chip interconnect of a die on a substrate is made by mating the interconnect bump onto a narrow interconnect pad on a lead or trace, rather than onto a capture pad. The width of the narrow interconnect pad is less than a base diameter of bumps on the die to be attached. Also, a flip chip package includes a die having solder bumps attached to interconnect pads in an active surface, and a substrate having narrow interconnect pads on electrically conductive traces in a die attach surface, in which the bumps are mated onto the narrow pads on the traces.
