  • Publication number: 20070119905
    Abstract: Component 3 is pressed onto a circuit board 4 so that their respective metal interconnects 5, 6 are in close contact with each other, and ultrasonic vibration is applied to the suction nozzle 14 holding the component 3. Friction is thereby generated between metal interconnects 5, 6 whereby the component 3 is bonded on circuit substrate. Suction nozzle 14 for handling components is made of stainless steel and has a working face 14a provided with a hardened layer 14b, or alternatively, suction nozzle 14 may have a suction head 14c having a working face 14a made of cemented carbide. Working face 14a of suction nozzle 14 is refined by polishing as required during the mounting operation.

  • Publication number: 20070108634
    Abstract: A first container member (9, 109, 212) mounting an electronic device (71, 171, 261) thereon and a second container member (2, 102, 202) are bonded with an adhesive (3, 103) or a metal layer (103, 251). Thus an inner space (90, 190, 211) is formed and the electronic device can be closed in the inner space at a low temperature. In the case the adhesive is used, an exposed surface of the adhesive is coated with a metal film (4) to improve the closeness of the inner space. Further, an electronic device (261, 272) may be mounted on the second container member so as to increase the electronic device arrangement density in a packaged electronic device.

  • Patent number: 7071090
    Abstract: A method of forming a bump electrode on an IC electrode includes the steps of forming a ball bond on an IC electrode by a wire bonding apparatus, moving a bonding capillary upward, moving the bonding capillary sideways and then downward, bonding an Au wire to the ball bond portion, and cutting the Au wire. The Au wire is prevented from coming in contact with portions around the ball bond portion other than the ball bond portion by presetting a descent position of the bonding capillary to a position higher than a position in which the ball bond is formed.

  • Publication number: 20050191838
    Abstract: A preheat device (160) is provided to execute, before forming bumps (16) to electrode parts (15), a pre-formation temperature control for bonding promotion to promote bonding between the electrode parts and the bumps during bump formation. Metal particles of the electrode parts can be changed to an appropriate state before the bump formation. Phenomenally, a bonding state between the electrode parts and the bumps can be improved as compared with the conventional art. In a further arrangement of the present invention, semiconductor components with bumps can be heated under a bonding strength improvement condition by a bonding stage (316) through controlling the heating by a controller (317).

    Abstract: The present invention provides a bump-joining apparatus, a bump-joining method, and a semiconductor component-manufacturing apparatus whereby bumps and electrode portions of circuit board are perfectly joined with higher join strength than in the conventional art. The apparatus includes a vibration generation device, a pressing device and a control unit, wherein bumps are pressed to electrode portions of a circuit board and vibrated with ultrasonic waves after reaching an initial contact area before reaching a join-completed-contact area at a completion of the joining, so that the bumps are more perfectly joined to the electrode portion than in the conventional art which vibrates the bump only after reaching the join-completed-contact area. Larger join strength is achieved than in the conventional art.
