Abstract: An electronic package including as part thereof a thermally conductive arrangement for restricting thermal fluid material motion about a heat-generating device, thereby assuring effective heat transference from the heat-generating device (e.g., module) to a cooling member (e.g., spaced heat sink), this arrangement preferably including: (1) a thermal fluid (e.g., thermal grease); and (2) structural elements (e.g., wire mesh, heat sink ridges, etc.). For restricting fluid movement, sealing structures (e.g., external gaskets) may be used to further assure fluid containment to a specified location. Pressure generation means (e.g., a plunger) can be used to increase fluid pressure when pressure droppages occur.

Abstract: A support structure is attached to the front or back side of a flexible circuit by direct mounting to the flexible circuit flat ribbon cable, thereby providing a stress-free region of the cable in which the flexible circuit electrical components can be mounted. The support structure comprises a flat ring that is attached to the cable by adhesive, soldering, or mechanical fastening. The flat ring mounts on one side of the flat ribbon cable and encloses an area of the cable that is sufficiently large for the mounting of the flexible circuit electrical components. The flat ribbon cable within the enclosed area is held flat and free from stress, even as the cable is handled. Thus, any components mounted within the enclosed area are not subjected to bending moments. The invention also can be incorporated into cable connectors, such as multi-pin connectors at the ends of cables, and can include support hooks and air cooling baffles.
