    摘要: A circuit board and a method for fabricating a circuit board are provided. The circuit board includes a dielectric core comprising a first surface and a second surface and a conductive layer comprising a first surface and a second surface. The first surface of the conductive layer is coupled to the second surface of the dielectric core. A first region of the second surface of the conductive layer is smooth and a second region of the second surface of the conductive layer is rough. The first region of the second surface of the conductive layer is operable to support high speed signaling and the second region of the second surface of the conductive layer is operable to support non-high speed signaling.

    摘要: Disclosed is a semiconductor package structure that incorporates the use of conductive pins to electrically and mechanically connect a semiconductor module and a substrate (e.g., printed wiring board). Specifically, one or both ends of the pins are hooked and are adapted to allow a press-fit connection with the walls of the plated through holes of either one or both of the semiconductor module and the substrate. The hook-shaped ends of the pins may have one or more hooks to establish the connection. Additionally, the pins may be formed of a temperature induced shape change material that bends to allow engaging and/or disengaging of the hook-shaped ends from the walls of the plated through holes.

    摘要: An LGA structure is provided having at least one semiconductor device over a substrate and a mechanical load apparatus over the semiconductor device. The structure includes a load-distributing material between the mechanical load apparatus and the substrate. Specifically, the load-distributing material is proximate a first side of the semiconductor device and a second side of the semiconductor device opposite the first side of the semiconductor device. Furthermore, the load-distributing material completely surrounds the semiconductor device and contacts the mechanical load apparatus, the substrate, and the semiconductor device. The load-distributing material can be thermally conductive and comprises an elastomer and/or a liquid. The load-distributing material comprises a LGA interposer adapted to connect the substrate to a PCB below the substrate and/or a second substrate. Moreover, the load-distributing material comprises compressible material layers and rigid material layers. The load-distributing material comprises a rigid material incased in a compressible material.

    摘要: The present invention relates to computer hardware design and in particular to a printed circuit board comprising wiring dedicated to supply electric board components such as integrated circuits with at least three different reference planes. In order to provide a printed circuit board having an improved signal return path for basically all relevant signal layers at transitions between card, connector, module and chip while still holding the cross-section structure simple, it is proposed to establish a layer structure whereina) a split voltage plane is located adjacent to one side of one of said reference planes and comprises conducting portions for all of said at least three different voltage levels in respective plane parts, andb) a signal layer being located adjacent to said reference planes.
