  • Electronic component, method of sealing electronic component with resin, and apparatus therefor
    Patent number: 6438826
    Abstract: A resin seal apparatus includes a movable bottom die vertically moved by an elevator mechanism, a transport mechanism horizontally moving the movable bottom die having placed thereon a printed circuit board with a semiconductor chip mounted thereon, an intermediate die abutting against a periphery of the printed circuit board when the movable bottom die is moved upward, a film of resin stretched by a film stretch mechanism over the intermediate die and the printed circuit board, a die for a chip, pressing a back surface of the semiconductor chip via the film of resin, and a top die pressing a top surface of the intermediate die via the film of resin. This apparatus allows a PCB with a semiconductor chip mounted thereon in the form of a flip chip to be sealed with resin in a reduced period of time to fabricate an electronic component.
    Type: Grant
