  • Patent number: 9414526
    Abstract: A cooling apparatus is disclosed, which may include multiple heat producing units. The cooling apparatus may also have a thermal interface material (TIM) to facilitate heat transfer away from the heat producing units. The cooling apparatus may also have multiple heat sink columns located above, and designed to conduct heat away from, corresponding heat producing units, through thermally conductive contact with corresponding portions of the TIM layer. The cooling apparatus may also have a load plate located above the heat sink columns, designed to hold the heat sink columns in a relatively fixed position above the heat producing units. The TIM layer may have an initial compressed state between the heat sink columns and the corresponding heat producing units. Each of the heat sink columns may be designed so that, in operation, the corresponding portion of the TIM layer may have a further compressed state.

  • Publication number: 20160197053
    Abstract: Embodiments relate to a method and apparatus for rework of a BGA package. Memory shape material is placed adjacent to a plurality of solder joints of the package. Stimulation is applied to the material, with the stimulation causing the material to change from a non-stimulated shape to a stimulated shape. This stimulation causes an expansion of the material. As the material expands, it exerts a tensile force on the BGA package and an adjacently positioned carrier, causing a separation of the two components, while mitigating collateral heat of adjacently positioned components.

  • Publication number: 20160174416
    Abstract: An electronic module is provided in which a chip is disposed over a substrate and electrically connected to the substrate by a plurality of electrical connect structures disposed between the chip and the substrate. A heat distributor, fabricated of a thermally conductive material, is disposed between the chip and the substrate and sized to extend beyond an edge of the chip to facilitate conduction of heat laterally out from between the chip and substrate. The heat distributor includes openings sized and positioned to allow the electrical connect structures to pass through the heat distributor without electrically contacting the heat distributor. The heat distributor is electrically isolated from the electrical connect structures, the chip and the substrate. In one implementation, the heat distributor physically contacts a thermally conductive enclosure of the electronic module to facilitate conduction of heat from between the chip and substrate to the enclosure.

  • Publication number: 20160172324
    Abstract: A method for aligning a chip onto a substrate is disclosed. The method includes, depositing a ferrofluid, onto a substrate that has one or more pads that electrically couple to a semiconductor layer. The method can include a chip with solder balls electrically coupled to the logic elements of the chip, which can be placed onto the deposited ferrofluid, where the chip is supported on the ferrofluid, in a substantially coplanar orientation to the substrate. The method can include determining if the chip is misaligned from a desired location on the substrate. The method can include adjusting the current location of the chip in response to determining that the solder balls of the chip are misaligned from the desired location on the pads of the substrate, until the chip is aligned in the desired location.
