Abstract:
An article and method for making and repairing connections between first and second circuits, such as flex circuits. The article (10) includes: a flexible dielectric substrate (12) having first and second edges 14/16, and a plurality of conductive circuit traces (18) arranged on or within the substrate, wherein each of the traces extends from proximate the first edge (14) to proximate the second edge (16). Each of the circuit traces (18) includes: a first connection feature (20) disposed proximate the first edge (14); a second connection feature (22) disposed proximate the second edge (16); and at least one third connection feature (24) disposed between the first and second edges (14/16). Each of the first, second, and third connection features (20/22/24) is a plated through hole, a plated blind via, or a mounting pad. This article (10) may be used to connect together the first and second circuits (50/60) using the first and second connection features (20/22), such as by soldering. If either of the two circuits needs to be subsequently detached (e.g., because of a component failure), the article (10) may be cut so as to present a set of third connection features (24) to which a new replacement circuit may be connected.
Abstract:
본 발명은 몰드부에 내장된 마이크로 칩에 대해 몰드부의 외부와 마이크로 칩이 상호 인터페이스 하는 필름을 부착시키되, 제품의 불량률을 현저히 낮춘 필름 레이어 부품소자에 관한 것이다. 특히, 본 발명은 합성수지재로 이루어진 몰드부의 중앙부를 하방으로 소정 깊이 함몰시키고 함몰된 부분의 바닥면을 소정 너비 절개하는 개구부를 형성하며, 개구부에 대응하는 부분의 몰드부 하면에 박막 형태의 필름을 핫 프레싱으로 부착한 후, 그 함몰된 부분에 마이크로 칩을 내장하고 필름이 외부와 마이크로 칩을 상호 인터페이스 하도록 하는 기술이다. 본 발명에 따르면, 마이크로 칩을 내장하는 몰드부를 마이크로 칩과 별도로 몰드부와 필름을 먼저 핫 프레싱에 의해 접합시킴으로써 제조 후 제품의 불량률을 현저히 낮추었다는 장점이 있다.
Abstract:
A single side emitting, multi-segment linear light source is disclosed. Each segment of the light source has an LED, a light guide with light extraction features, and a bent reflector sheet. All of this is mounted on a PCB that is bent in a plurality of places. The PCB provides mechanical support, electrical contacts and conducts heat generated by the LED away. Electrical connections are provided across the bend in the PCB using novel means.

L'invention concerne un procédé pour connecter des premiers plots (16) d'une structure (1) proteuse d'electrodes (4) propres à mesurer ou à stimuler une activité d'origine physiologique à des seconds plots (17) d'au moins un circuit aval (2), chaque second plot (17) étant traversé par une ouverture (15) perforant le circuit aval. Le procédé comporte les étapes suivantes : a) placer le circuit aval sur ladite structure, de sorte que l'ouverture (15) d'un second plot (17) se trouve en face d'un premier plot (16); et b) déposer dans l'ouverture (15) du second plot (17) un matériau conducteur (18) assurant la connexion entre le second plot et le premier plot en regard.
Abstract:
An apparatus and method for forming a conical or domed ring light having a plurality of light sources arranged at a desired angle with respect to an optical axis. Some of the dimensions of the illumination apparatus are first determined and, then using the appropriate formulas, the remaining dimensions of the circuit board are calculated. Thereafter, the calculated dimensions are employed to cut, from a planar flexible circuit board, the desired arcuate section(s). The light sources are then installed at desired locations on a first surface of the flexible circuit board and are each coupled to a common electrical connector, having one or a plurality of power sources, to facilitate supplying electrical power to each one of the light sources. The circuit board is then folded into a conical or domed configuration, with the light sources facing inward, and each abutted end and lateral surfaces of the folded circuit board is suitably secured or fastened to one another to permanently retain the flexible circuit board in its folded state.
