  • Publication number: 20060285300
    Abstract: A cooled electronic assembly includes an integrated-circuit device carrier (such as a printed circuit board), a device (such as a flip chip), a liquid pump, a molding material, a heat exchanger, and a cover. The device and the liquid pump are electrically connected to the integrated-circuit device carrier. The molding material is molded to the device, to the liquid pump, and to the integrated-circuit device carrier. The cover has a coolant channel fluidly connected to the heat exchanger, wherein the cover is attached to the molding material. The coolant channel and the heat exchanger together at least partially define a closed coolant circuit. The liquid pump is operatively connected to the closed coolant circuit. A method for cooling a printed circuit board includes placing a liquid coolant in the closed coolant circuit and electrically activating the liquid pump through the printed circuit board.

  • Publication number: 20060209516
    Abstract: An electronic assembly with integral thermal transient suppression includes an integrated circuit (IC) chip disposed within a cavity of an IC device package. A transient thermal suppression material (TTSM) is disposed in the cavity in thermal contact with the IC chip. A heat sink may also be provided in thermal contact with the chip. When present, the heat sink serves as a cover of the packaged IC chip and may include fins extending from an upper surface (in contact with air) and a lower surface (in thermal contact with the TTSM). The TTSM may be thought of as a phase change material that absorbs energy dissipated by the IC chip in a phase change event.

  • Publication number: 20060120058
    Abstract: A circuit board assembly having a laminate construction of multiple layers, such as a LTCC ceramic substrate, with conductor lines between adjacent pairs of layers. A heat sink is bonded to a first surface of the substrate, and a cavity is defined by and between the heat sink and the substrate such that a base wall of the cavity is defined by one of the layers with conductor lines thereof being present on the base wall. A surface-mount circuit device is received within the cavity, mounted to the base wall, and electrically connected to the conductor lines on the base wall. The device is received within the cavity such that a surface of the device contacts a surface region of the heat sink. The surface of the device is bonded to the surface region of the heat sink to provide a substantially direct thermal path from the device to the heat sink.

  • Publication number: 20060033236
    Abstract: A method of making a fluid cooled microelectronic package in which fluid is circulated through the package in fluid-carrying channels defined at least in part by voids in an encapsulant that surrounds the package components. Preferably, the encapsulant channels are defined in part by heat producing components of the package so that coolant fluid directly contacts such components. The coolant fluid can be electrically conductive or non-conductive depending on the type of components being cooled. The coolant channels are formed by insert-molding a form in the encapsulant, and removing the form following the molding process. Alternately, the encapsulant is formed in two or more pieces that are joined to form the package, and the coolant channels are defined by recesses formed in at least one of the encapsulant pieces.

    Abstract: A circuit board assembly comprising a laminate substrate and a surface mount device having a CTE less than that of the laminate substrate and attached with at least one solder joint to a first surface of the laminate substrate. The assembly further includes a localized stiffener attached to a second surface of the laminate substrate so as to be directly opposite the circuit device. The localized stiffener is formed of a material and is shaped so that, when attached to the laminate substrate, the stiffener is capable of increasing the thermal cycle fatigue life of the one or more solder joints that attach the device to the substrate.

  • Publication number: 20050081377
    Abstract: An overmolded electronic assembly having an electromagnetic interference shield, in the form of a thin metal film or foil, coupled to the top of or within an overmolded body. The shield effectively reduces the amount of electromagnetic interference (“EMI”) emissions from penetrating within the assembly to the circuit board without substantially increasing the cost of the unit. Thus, an electronic assembly having improved vibration, moisture, and EMI emission resistance is achieved as compared with traditional overmolded or metal assemblies. Further, because the shield can be formed on the electronic assembly in one continuous processing step, a substantial savings in time and cost for the manufacturing process is also realized.

  • Publication number: 20050082660
    Abstract: An electronic package and packaging method in which integral convective fins are formed of portions of a leadframe from which electrical leads are also formed. The leadframe comprises a base and first and second sets of leads extending from the base. The first set of leads is separated from the base and from the second set of leads, such that each lead of the first set has an interior end adjacent but separate from the base, and each lead of the second set has an interior portion that remains attached to the base. A circuit device is mounted to the base and electrically connected to the interior ends of the first set of leads. The device, base, and interior ends and portions of the leads are then encased within a housing. Exterior ends of the leads remain outside the housing as package terminals and thermal dissipaters.
