    Abstract: A dug portion (50) in which a die-bonding material is filled is provided to a lower surface of a stamping nozzle (42) used in a step of applying the die-bonding material onto a chip mounting portion of a wiring board. Planar dimensions of the dug portion (50) are smaller than external dimensions of a chip to be mounted on the chip mounting portion. In addition, a depth of the dug portion (50) is smaller than a thickness of the chip. When the thickness of the chip is 100 ?m or smaller, a problem of crawling up of the die-bonding material to an upper surface of the chip is avoided by applying the die-bonding material onto the chip mounting portion using the stamping nozzle (42).

  • Publication number: 20120327658
    Abstract: A lead frame for a light-emitting diode (LED). The lead frame includes a first lead and a second lead. Each lead includes a top portion and an integrated wire-clasping portion. The first and second top portions each angle away from the center of the lead frame to form an increasingly larger gap between the two leads. The wire-clasping portions of each lead initially lie in a common plane and are adjacent one another. After securing the wire to the wire-clasping portions of the lead frame, the leads of the lead frame are rotated or twisted approximately 90 degrees such that the wire-clasping portions of the leads are opposite one another, rather than lying in the same plane. The wires and attached lead frame are inserted into a lampholder, the lampholder recesses receiving the top tabs of the lead frame and holding the wires and lead frame in place.
