    摘要: A thermally conductive mounting flange of an IC package is placed directly on a heat sink surface between respective sections of single layer PC board attached to the heat sink, such that electrical leads extending from opposing sides of the package are positioned over corresponding conductive areas formed on the surface of the respective adjacent PC board section. The leads are electrically coupled with the conductive areas by respective tie-down screws fastened through dielectric isolating washers. The screws are tightened sufficiently against the isolating washers so as to press the respective package leads into solid electrical contact with the conductive areas. Portions of the respective leads and conductive areas surrounding the tie-down screws are cut-away to prevent electrical contact, in order to avoid shorting the leads and/or conductive areas to the heat sink via the tie-down screws. Alternately, respective ends of a retaining spring used to secure the IC package to the heat sink mounting flange are also secured by the package lead tie-down screws, such that the screws both secure the package against the heat sink and press the package leads into solid electrical contact with the respective conductive areas.

    摘要: A top surface of a protective cover of an IC component package is provided with a centered-protrusion, e.g., such as a cylindrical peg, that extends above the cover. A retaining-spring is formed by twisting a resilient (e.g., metal) metal strip into a ribbon-like shape having opposing ends that extend from a curvelinear bottom surface. The bottom surface of the retaining-spring is provided with an opening configured to mate with the centered protrusion on the package cover, such that the opposing ends of the retaining-spring extend away from the package cover at substantially the same, albeit reverse angles. In order to mount the IC package to a heat sink, the bottom surface of the retaining-spring may be compressively mated onto the package cover at the same time the package is inserted between two substantially parallel walls protruding from the heat sink surface, wherein the walls are distanced from each other. just so as to cause moderate compression of the opposing ends of the spring toward each other as the package is inserted against the heat sink surface. The opposing surfaces of the two walls are provided with a plurality of notches formed substantially parallel to the heat sink surface in a "ratchet-type" relief pattern, such that the opposing ends of the retaining-spring are held into place by respective notches, once the IC package is secured against the heat sink.
