Abstract:
An electromechanical module comprises an IC package having a top surface which dissipates heat and a heat sink which is held by a frame in direct thermal contact with the top surface. This frame includes a pair of spaced-apart elongated beams and a pair of end members which connect to opposite ends of the beams; and the beams together with the end members surround the IC package and expose all of the top surface. Thus, the heat sink can be in direct thermal contact with all of the top surface and can extend past it without having to step up to get over the frame. To attach/remove the frame from the IC package, each end member has at least one leg with a lip that catches on the bottom surface of the IC package; and, when the beams are manually bowed, the lips on the legs move further apart and past the bottom surface.
Electro-Mechanical Assembly Of High Power And Low Power Ic Packages With A Shared Heat Sink

International Classification:
H01L 2302
US Classification:
257713
Abstract:
An electro-mechanical assembly includes a high power IC package and a low power IC package which are mounted with a space between them on a single substrate. Both of these IC packages have flat top surfaces which dissipate heat; and due to various manufacturing tolerances, those surfaces are non-coplanar with respect to each other. To cool these two IC packages, a single heat sink is provided which has a thin flat core that overlies both of the IC packages as well as the space between them, and cooling fins extend from the top of the core. A pair of contact regions are provided on the bottom of the core which respectively are supported by the flat surfaces of the IC packages; and the contact region for the high power IC package is a projection from the core which is a) substantially smaller in average cross-sectional area, parallel to the core, than the flat surface of the high power IC package, b) aligned with a high power chip in the high power IC package, and c) long enough to prevent any portion of the core from touching the flat surface of the high power IC package, despite its non-coplanarity.
