  • Patent number: 7156538
    Abstract: Disclosed herein is an LED package for a backlight unit. The LED package includes a plurality of LEDs, a die bonding part, a wire bonding part and a body. The die bonding part, on which the plurality of LEDs is arranged, allows the first electrodes of the LEDs to be electrically connected to an external circuit. The wire bonding part is spaced apart from the die bonding part by a predetermined distance to be insulated from the die bonding part and allows the second electrodes of the LEDs to be electrically connected to the external circuit so that the LEDs are operated. The body has a molding cup which is used to fill a space above the LEDs with transparent resin and a base on which the die bonding part and the wire bonding part are arranged.

  • Publication number: 20050199884
    Abstract: A high power LED package, in which substantially planar first and second lead frames made of high reflectivity metal are spaced from each other for a predetermined gap. An LED chip is seated on at least one of the lead frames, and having terminals electrically connected to the lead frames, respectively. A package body made of resin seals the LED chip therein while fixedly securing the lead frame in the bottom thereof. The encapsulant preferably fills up the gap between the first and second lead frames. The LED package is structured to raise thermal radiation efficiency thereby reducing the size and thickness thereof.

  • Patent number: 6928719
    Abstract: A method for fabricating a surface acoustic wave filter chip package includes: mounting a surface acoustic wave filter chip on a substrate; forming a underfill in a space between the substrate and the chip; forming a metal shield layer on a whole outer wall of the chip by using a spray process; and molding resins on the metal shield layer. The metal shield layer is formed from a conductive epoxy with the use of a spray nozzle.

  • Patent number: 6809587
    Abstract: An active predistorting linearizer with agile bypass circuit for safe mode operation is used in conjunction with an amplifier. This linearizer comprises a controllable input variable-attenuator and drive-amplifier circuit supplied with the input signal to attenuate and amplify the input signal. A predistorter includes a controllable phase-shifting and amplitude-adjusting path supplied with the attenuated and amplified input signal to distort the latter signal and produce a predistorted output signal. A controllable output variable-attenuator and drive-amplifier circuit is supplied with the predistorted output signal to attenuate and amplify this predistorted output signal before supplying it to the power amplifier. A phase-shifting and amplitude-adjusting controller is connected to the controllable input variable-attenuator and drive-amplifier circuit, the controllable phase-shifting and amplitude-adjusting path, and the controllable output variable-attenuator and drive-amplifier circuit.

  • Patent number: 6730539
    Abstract: A method of manufacturing a semiconductor device package includes forming a patterned photoresist film with windows for exposing a plurality of connection bump areas on a conductive substrate, forming metal plating layers on the connection bumps area using the photoresist film, and forming first gold plating layers on the metal plating layers. The metal plating layers prevent the diffusion of the first gold plating layers into the conductive substrate. According to the method, high-qualified conductive layers are formed on the connection bumps by a simplified manufacturing process. Further, connection bumps having an upper part in an almost hemispherical shape are formed on the first gold plating layers, thereby improving the reliability of the semiconductor device package.
