  • Patent number: 4826068
    Abstract: A bonding device for effecting outer lead bonding is disclosed which comprises a bonding stage, a pair of bonding tools, and lead supporting means. The lead supporting means may take the form of a pair of projections formed on the upper surface of the bonding stage at horizontal locations thereof which are situated below the lead supporting portion of the tape carrier. Alternatively, the lead supporting means may take the form of a pair of horizontally extending rectangular columns which are retractably inserted into the above specified horizontal locations of the upper surface of the bonding stage. Thus, leads can be formed simultaneously with the outer lead bonding. The bonding stage may be divided into upper and lower stages, and the projections may be formed on the upper surface of the lower stage to extend through holes formed in the upper stage. This structure makes the projections retractable.

  • Patent number: 4751199
    Abstract: A lead frame that is suited for use on array types of integrated circuit packages to provide a high degree of compliance for absorbing mechanical stress induced by thermal changes includes a series of individual terminal elements that are connected in a strip form by means of break tabs disposed between adjacent elements. Each terminal element provides two spaced, generally parallel mounting surfaces that are resiliently connected to one another by means of an integral intermediate section. While the terminal elements are interconnected in strip form, one of the mounting surfaces of each element can be bonded to an associated attachment region on the semiconductor substrate. After all of the terminals of the strip have been so bonded, the break tabs between adjacent terminals can be removed to thereby separate the terminals from one another. The package which then results contains discrete compliant terminals which are suitable for subsequent surface attachment to the printed circuit board.
