    Abstract: Enlarged spacing is provided between rows of vias in a ball grid array (BGA) multilayered printed wiring board land pattern in which the lands in the pattern are connected to the vias by a link connector by rotating, elongating, and/or truncating selected consecutive link connectors and rotating their respective corresponding vias in a row or column or selected consecutive rows or columns to achieve the enlarged spacing between rows or columns of vias in the BGA land pattern. Enhanced spacing between selected grid columns or rows of vias is provided such that some of the grid pitches for the vias are equal to that of the standard BGA and at least some are of a greater grid pitch.

    Abstract: An electronic system having a backplane designed for efficient routing of signal traces. The system includes two or more daughter cards that are connected to multiple other daughter cards in the system. These daughter cards are mounted centrally to the backplane in the system. Connections between those two daughter cards and the backplane are made through electrical connectors that are distributed in columns along the length of the daughter cards. The connectors are positioned with space between the connectors. The space forms routing channels such that signals that must be connected to the central cards from a daughter cards on either side may be routed through the routing channels.

    Abstract: A multi-level circuit board for efficiently routing electrical signals is disclosed. The circuit board includes a contact layer comprising a first substrate and formed with a set of contact pads disposed across a relatively large surface area. The contact layer also includes a set of engagement contacts corresponding to the contact pads and arrayed in a densely packed surface area. A plurality of subsequent layers are disposed in fixed stacked relationship to the contact layer. Each subsequent layer includes a subsequent substrate, and a conductive pattern formed on the subsequent substrate and defining a plurality of signal paths. Conductive vias are coupled to the contact pads and the engagement contacts and are formed through the contact layer and one or more of the plurality of subsequent layers. The vias communicate with the respective signal paths and include selected sets of staggered vias configured to optimize the routing of the signal paths along the respective subsequent layers.

    Abstract: An apparatus and system comprising electrical interconnection devices (EIDs), such as printed wiring boards (100), semiconductor packages (101), and printed circuit boards, having novel via and signal trace positioning. The vias (140) may be positioned off-center from the pattern of the surface pads (102, 103). Via groups, or staircase vias, connect surface pads with vias extending into the electrical interconnection device. The via groups convert the pad geometry on the surface to a more open via pattern on one or more internal layers. The EID comprises a plurality of pads formed on a surface for providing electrical connections to another EID. A plurality of vias each extend from a corresponding pad to another layer of the printed wiring board. Each via is offset from a central location of its corresponding pad. A via group comprises a plurality of vias with a first via connecting a surface of the electrical interconnection device to a first inner layer electrically connects a pad on a surface of the electrical interconnection device to a second via. The second via extends from the first inner layer to a second layer of the electrical interconnection device. The centers of the first via and the second via are non-collinear. Another EID includes a uniformly spaced set of pads on the surface. Via groups, comprising a first set of vias and a second set of vias, extend from the uniformly spaced surface pads. Spacing among the second set of vias is non-uniform.
