    Abstract: In a transmission circuit board, ground terminal portions (10) are disposed at every other two rows in both end columns. Each of signal circuit layers (20) includes at least a pair of adjacent signal connecting portions electrically connected to a pair of the wiring portions (21, 22) arranged in parallel in a row direction and the column direction different from those on an adjacent signal circuit layer. Each of the ground layers is electrically connected to at least one of the ground terminal portions (10) in the both end columns.

    Abstract: For electrical backplanes and the like, a power plane adaptation to improve the propagation of high-speed signals through clearances in an embedded power plane is disclosed. In exemplary embodiments, the power plane is segmented in a high-speed connector region, such that a portion of the metal layer that forms the power plane is retained in the high-speed connector region—but isolated from the power-delivery portion of the power plane. The isolated portion is connected to digital ground, and clearances are formed therein where high-speed signaling throughholes will pass through the region. In some embodiments, various attainable advantages include better manufacturability, better matching and control of high-speed signaling throughhole impedance, and improved noise isolation. Other embodiments are described and claimed.
