    Abstract: Techniques and mechanisms for promoting heat conduction in a packaged device using a heat spreader that is fabricated by a build-up process. In an embodiment, 3D printing of a heat spreader successively deposit layers of a thermal conductor material, where said layers variously extend each over a respective one or more IC dies. The heat spreader forms a flat top side, wherein a bottom side of the heat spreader extends over, and conforms at least partially to, different respective heights of various IC dies. In another embodiment, fabrication of a portion of the heat spreader comprises printing pore structures that contribute to a relatively low thermal conductivity of said portion. An average orientation of the oblong pores contributes to different respective thermal conduction properties for various directions of heat flow.

    Abstract: Embodiments herein relate to torque controlled drivers to simultaneously drive fasteners to secure a thermal transfer device to an integrated circuit package. In various embodiments, a torque controlled driver may include a gearbox, a driver with a torque controller and a motor with a rotating shank, a motor gear coupled concentrically with the rotating shank, a bit drive gear in rotational engagement with the motor gear to drive a bit sized to drive a fastener to secure a thermal transfer device to an integrated circuit package, where the gearbox is to hold the motor gear in a position about a motor gear rotational axis and the drive gear about a drive gear rotational axis such that the motor gear and the bit drive gear maintain rotational engagement as the motor gear rotates. Other embodiments may be described and/or claimed.
