  • Publication number: 20050146054
    Abstract: The present invention provides an electronic packaging process. The surface of the chip carrier includes at least a chip attachment region and a film attachment region adjacent to the chip attachment region. At least a baffle is formed on the surface of the chip carrier, between the chip attachment region and the film attachment region. After attaching the thin film to the film attachment region of the chip carrier through an affixture layer, the chip is electrically and physically connected to the chip attachment region of the chip carrier through an adhesive layer. The baffle can effectively prevent the gas that is released from the adhesive layer from damaging the bonding between the thin film and the affixture layer. Therefore, almost no bubbles are formed and good electrical connection between the thin film and the affixture layer is maintained.

    Abstract: A flip chip package mainly comprises a chip, a leadless lead frame. The leadless lead frame has a die paddle and a plurality of leads. The active surface of the chip has a plurality of bonding pads formed thereon. Besides, a plurality of bumps formed on the bonding pads are electrically connected to the chip, the leads and the die paddle. Therein, the die paddle electrically connected to the chip via the bumps not only prevents the chip from being dislocated but also provides another grounding and heat transmission paths to enhance the electrical, thermal and mechanical performance of the flip chip package. Similarly, the bumps formed on the bonding pads of the chip are electrically connected to the leads so as to fix the chip to the lead frame more securely.
