Abstract:
A method of forming a multilayered wiring board having a multilayered wiring structure includes the steps of forming a first mesh wiring layer having a plurality of holes therein, and forming a second wiring layer having a plurality of wirings undulating up and down so as to descend into the holes formed in the first wiring layer. In another method, the first wiring layer is formed with a plurality of protrusions and the wirings of the second wiring layer are formed between the protrusions. In the wiring boards formed according to the methods of the present invention, crosstalk between the wirings is suppressed.
Abstract:
An electrical circuit package wherein a flexible support member having conductive materials and electronic components thereon is fused with a substrate which acts as a support for the film. This results in a unitary packaged circuit. In one embodiment the film is a decal on which certain portions have a substrate fused thereto. In other embodiments, various layers of conductive materials are applied and molded into the substrate to form a variety of electronic functions. The circuit package lends itself to high production and reliability as well as cost savings.
Abstract:
A semiconductor fabrication having thermal characteristics comparable to hybrid ceramic packages comprises a flexible copper foil printed circuit on a thin polyimide film layer thermally laminated to a metal surface, such as aluminum, with a high temperature thermal plastic, such as polyetherimide. A semiconductor die is attached to a relatively thick metal heat spreader which in turn is attached to at least a portion of the copper foil. The resultant structure is a semiconductor package which has a thermal performance comparable to that of typical hybrid ceramic packages.
Abstract:
Packaging of microelectronics utilizing a series of various size cylindershich are assembled and sealed from the environment, providing electrical connections out opposite ends of the cylinders and providing for a center opening in the inner cylinder to allow other structure such as a warhead to be mounted therein are aspects of this invention.
Abstract:
A curved printed circuit board is made in accordance with a method which ensures accurate registration between printed circuit patterns carried by the two outer surfaces of the board.
Abstract:
The disclosure describes an antimicrobial protection device using antibacterial and virucidal electromagnetic energy to provide protection. Electromagnetic energy may be supplied by light source(s) such as LED(s). Lighting apparatus may be configured to project electromagnetic energy in an energy barrier over an individual or portion thereof, such as the individual's airways and eyes. Light source(s) may be constructed or configured to emit electromagnetic energy in wavelengths at about 405 nm and/or between about 200 nm to about 220 nm. Lighting apparatus may be configured in a ring and may be mounted above the user's head such that the lighting apparatus projects a bactericidal and/or virucidal curtain of light around the user's head, killing or inactivating microbes before reaching the user's eyes, nose, or mouth. Apparatus of the present disclosure may be useful for medically fragile children (including those in wheelchairs), medically fragile people, and medical personnel in high-risk infectious areas.
Abstract:
A lighting module of a motor vehicle signaling device includes a ceramic substrate having opposite first and second faces, and a plurality of selectively activatable light sources mounted on the first face of the ceramic substrate. Each of the first and second faces of the ceramic substrate are provided with at least a first and a second respective interconnection layer. The ceramic substrate comprises a plurality of through holes designed to interconnect the first interconnection layer to the second interconnection layer.
Abstract:
The present disclosure provides a display module and a method for coating the same, which can prevent and/or reduce the occurrence of black seam between display modules that are arranged adjacent to each other. According to an example aspect of the present disclosure, a display module includes a printed circuit board; a plurality of luminous elements arranged at predetermined intervals on the printed circuit board; and a coating layer comprising a coating disposed between the respective luminous elements, disposed around side surfaces of the respective luminous elements positioned at an outermost, and formed to have a height that is substantially equal to a height of the side surfaces of the luminous elements, the coating being configured to block side light of the respective luminous elements.
