    摘要: A plurality of wiring traces are formed on a base insulating layer, and a metal layer is formed on the opposite surface of the base insulating layer. Two adjacent wiring traces constitute a transmission line pair. The width of the wiring trace is set to not more than 250 μm, and the distance between the adjacent wiring traces is set to not less than 8 μm. The thickness of the base insulating layer is selected to cause differential impedance of the transmission line pair to be not less than 10 Ω and not more than 50 Ω.

    摘要: The present invention provides a mounted structure of circuit board which can be prepared by a simple method and exhibits a good heat dissipation from chip and undergoes relaxed heat stress and a multi-layer circuit board to be incorporated in the mounted structure. A novel mounted structure of circuit board is provided comprising a core material embedded in an insulating layer, said core material having a metal layer with a heat conductivity of not less than 100 W/m·K provided on at least one side of an Ni—Fe alloy foil, said insulating layer comprising a wire conductor provided and a semiconductor element mounted on at least one side thereof, characterized in that a solder metal member for heat conduction is provided interposed between said semiconductor element and said core material so that said semiconductor element and said core material are connected to each other. The mounted structure of circuit board comprises a 6-layer circuit board 2 having a laminate of three sheets of double-sided circuit boards 1 and a chip 13 connected to a circuit 5 on the uppermost layer. The core material 3 embedded in the intraboard insulating layer 4 in various double-sided circuit board 1 comprises a copper layer 3a having a heat conductivity of 393 W/·K provided on at least one side of an Ni—Fe alloy foil 25. The chip 13 and the underlying core material 3 are connected to each other with a solder metal member 10. The core material 3 on the horizontally adjacent double-sided circuit boards 1 are similarly connected to each other with the solder metal member 10.

    摘要: A fixing device includes a fixing member, pressure member, first temperature detector, and pressure adjustment mechanism. The pressure member presses against the fixing member to form a nip though which a recording medium bearing a toner image thereon is conveyed. The first temperature detector detects a temperature of the fixing member. The pressure adjustment mechanism performs an adjustment to contact pressure between the fixing and pressure members to be lower than an appropriate pressure for image fixing at the detected temperature of the fixing roller or separation of the pressure roller from the fixing member for a part of a period between a time at which a tailing end of a precedent recording medium is conveyed out from the nip and a time at which a leading end of a following recording medium is conveyed into the nip when a plurality of recording media are successively conveyed through the nip.
