    Abstract: Disclosed herein is a manufacturing method of a circuit board. The manufacturing method includes a first step for preparing a prepreg in which a core material is impregnated with an uncured resin. The prepreg has a through-hole surrounded by the core material and the resin so as to penetrate through the core material and the resin. The manufacturing method further includes a second step for housing a semiconductor IC in the through-hole, and a third step for pressing the prepreg so that a part of the resin flows into the through-hole to allow the semiconductor IC housed in the through-hole to be embedded in the resin.

    Abstract: Electronic devices may contain electrical systems in which electrical components are mounted on a substrate such as a printed circuit board. The electrical components may include surface mount technology components. Multiple surface mount technology components may be stacked on top of each other and beside each other to form an electrical component that minimizes the amount of area that is consumed on a printed circuit board. Noise suppression circuits and other circuits may be implemented using stacked surface mount technology components. Surface mount technology components placed on the printed circuit board may be pushed together and subsequently injection molded to form packed component groups. An integrated circuit may be mounted to the printed circuit board via an interposer and may cover components mounted to the printed circuit board. An integrated circuit may be mounted over a recessed portion of the printed circuit board on which components are mounted.

  • Publication number: 20140085853
    Abstract: A display apparatus including a display and a waveguide plate is provided. The display panel includes multiple rows of display units and multiple rows of solar cell units. The display units and the solar cell units are substantially parallel to a first direction and alternately arranged along a second direction perpendicular to the first direction. The waveguide plate is disposed at one side of the display panel. A first side of the waveguide plate adjacent to the display panel includes multiple microstructures. First and second structure surfaces of each microstructure respectively correspond to one row of the display units and one row of the solar cell units. When the display apparatus is disposed such that the second direction is perpendicular to a ground surface, an inclination of the first structure surface makes a thickness of the waveguide plate gradually decrease along an upward direction from the ground surface.

    Abstract: A computer processor retention device comprises a load frame, a load plate, and a pair of retractable cover members. The load frame may be secured to a circuit board around a processor mounting site. The load plate is pivotally coupled to the load frame and is pivotable between being open for receiving a processor at the processor mounting site and closed in engagement with a periphery of the received processor. The load plate has a window that is open to the processor mounting site when the load plate is closed. The retractable cover members span the window and are alternately movable along a track toward one another to cover the processor mounting site and away from one another to expose the processor mounting site.
