  • Patent number: 7096580
    Abstract: A thin, lightweight retention mechanism with a spring force holds an integrated circuit package to a circuit board. The retention mechanism consists of a pressure plate, a backing plate, and a fastening means for applying a deforming force to the plates, such as screws and nuts. The plates are paraboloid or dish-shaped and made of an elastically deformable material, such as steel. The fastening means simultaneously applies deforming forces to the peripheries of the plates to create a continuous spring force to effect electrical continuity between the integrated circuit package and the circuit board. In addition, a method of testing the retention mechanism and a method of assembling the retention mechanism are disclosed.

  • Patent number: 6661660
    Abstract: Two types of thermal management devices for efficiently dissipating heat generated by high performance electronic devices, such as microprocessors for desktop and server computers producing a power of near 200 Watts and high power electronic devices that are small and thin, such as those used in telephones, radios, laptop computers, and handheld devices. An integrated heat sink and spreader for cooling an item has a vapor chamber heat sink with a thinner first wall and a thicker second wall. The thicker second wall is engageable with the item in efficient heat transferring relationship. A plurality of heat-radiating fins are attached to the thinner first wall. An embedded direct heat pipe attachment includes a heat pipe embedded in a spreader plate that is in direct heat transferring contact with an item through a thin, uniform layer of thermal interface material.

  • Patent number: 4589547
    Abstract: A carrier (30) for thin flat electronic devices (36) is provided which has a high volumetric efficiency and is adapted for use with automatic handling equipment. The carrier (30) comprising a hollow tube (31) having a longitudinal interior bore (35) in which is placed a longitudinal cage of metal rails (38) which surround, guide, and hold the devices (36) in a stacked relationship. At least six rails (38) are required to avoid binding and jamming of devices (36) in bore (35). End caps (33a-b) and a moveable resilient plug (34) are used to retain the devices (36) firmly but gently in place to prevent chipping and scratching of the devices (36) during handling and shipment of the carrier (30), and to vary the capacity of the carrier (30). The carrier (30) is rugged, reuseable, and has a volumetric efficiency (devices/unit volume) three to eighteen times higher than prior art egg-crate type device carriers.
