摘要： A heat sink is placed in a heat transfer relationship with a substrate such as an integrated chip, chip carrier, or other electronic package, without imparting stressful forces to the substrate by connecting the heat sink to a frame which is connected to a support such as a printed circuit board or other suitable carrier on which the substrate is positioned. The heat sink extends through an aperture in the frame and is in heat transfer relationship with a surface of the substrate; however, it is mechanically decoupled from the substrate. The invention has particular application in thermally connecting large heat sinks to substrates that are surface mounted on the support using technologies such as ceramic ball or column grid arrays, plastic ball or column grid arrays, or solder balls or columns. In order to provide intimate contact between the substrate and the heat sink, the heat sink must be depressed coaxially through the aperture of the frame against a surface of the substrate and then secured by, for example, gluing while in contact with the surface. However, this downward force imparted by the heat sink is quickly reduced via relaxation of the lead/tin or other metallic elements of the surface mount. A heat sink in a heat transfer relationship with a substrate such as an integrated chip, chip carrier, or other electronic package. The heat sink is connected to a frame which is connected to a printed circuit board or other suitable support on which the substrate is positioned. The heat sink, which extends through an aperture in the frame is coupled to a surface of the substrate. The heat sink is mechanically decoupled from the substrate. Large heat sinks may be thermally connected to surface mount substrates mounted using technologies such as ceramic ball or column grid arrays, plastic ball or column grid arrays, or solder balls or columns. The heat sink is attached coaxially through the aperture to the substrate. After assembly and lead/tin or other metallic surface mount interconnects are relaxed such that the substrate and is completely supported by the frame and the heat sink imparts zero or nearly zero downward force. Because the heat sink moves freely within the aperture during assembly, the heat sink package is useful for a variety of different substrates. Preferably, the frame is a plate and a plurality of studs. The plate material are selected to match the thermal expansion of the underlying support, and the stud material matches the thermal expansion of the substrate. Thus the frame construction allows matching expansion and contraction of the assembly to the underlying substrate and support.

摘要： A chip package includes a substrate formed from a first die and its attendant wiring interconnections, having a first thermal coefficient of expansion. The first die includes primary input/output (I/O) interconnections for the chip package. Also provided is a second die that includes escape wiring formed on that die and coupled to the primary I/O interconnections through the first die. The second die has a second thermal coefficient of expansion similar to the first thermal coefficient of expansion. The chip package also includes connectors that couple the primary I/O interconnections of the first die to a second level package. An interposer may be provided to couple the primary I/O interconnections to the second level package. The second die is smaller than the first die. The peripheral area of the first die is left exposed when the second die is coupled to the first die so that sufficient I/O interconnections may be formed for the primary I/O interconnections on the first die. The second die provides and receives signals which may include the second die's primary I/O to and from the first die. Wiring may be shared between the first die and the second die in a manner optimal for design and manufacturing.

摘要： Solder compositions are introduced to interface between an IC chip and its associated heat exchanger cover. The solder compositions have a solidus-liquidus temperature range that encompasses the IC chip operational temperature range. The solder composition has the desired property of absorbing and rejecting heat energy by changing state or phase with each temperature rise and decline that result from temperature fluctuations associated with the thermal cycles of the integrated circuit chips. A path for high thermal conduction (low thermal resistance) from the IC chip to the heat exchanger to the ambient air is provided by an electronic module cover, configured as a cap with a heat exchanger formed or attached as a single construction, and made of the same material as the substrate, or made with materials of compatible thermal coefficients of expansion to mitigate the effects of vertical displacement during thermal cycling. The cap-heat exchanger cover is constructed to be compliant, and to contact both the IC chip and substrate.

摘要： A microelectronic module comprising at least two chips mounted to a chip receiving surface. Each chip having an edge including at least one chip input and one chip output. The chips are arranged such that the edge of one chip is opposite the edge of the other chip. The chips are spaced apart by a predetermined distance. Each chip includes at least one optical transmitter attached to the edge of the chip. The transmitter has an input coupled to the chip output and a transmission portion for generating optical signals at a predetermined angle and that are representative of signals inputted to the transmitter input. The microelectronic module further includes at least one optical receiver attached to the edge of the chip. The optical receiver has an output coupled to the chip input and a receiving portion for directly receiving optical signals generated by a corresponding optical transmitter of the other chip. The optical receiver and the corresponding optical transmitter form a transmitter/receiver pair. The predetermined distance and the predetermined angle prevent overlapping of the optical signals of the transmitter/receiver pairs.
