    摘要: Via holes are formed in an electrically conductive power plane. Photo-imageable dielectric (PID) material is applied to one side of the power plane filling the via holes. The power plane side with no PID material is exposed to light energy to cure the PID material in the via holes. A developer is used to remove any uncured PID material. Signal plane assemblies comprising a conductive signal plane and a dielectric layer are laminated onto the filled power plane forming a two signal and one power plane (2S1P) structure. In another embodiment, the power plane has PID material applied from both sides. A photo-mask is applied to the power plane and the PID material in the via holes is cured with light energy. A developer is used to remove uncured PID material. Signal plane assemblies, as described above, are laminated onto the filled power plane forming a 2S1P structure.

    摘要: A printed circuit board and a method of making same in which the board includes a common power plane having dielectric layers on opposing sides thereof and a signal layer on each of said dielectric layers, each signal layer comprising a plurality of substantially parallel signal lines running in substantially similar directions across said signal layers. Predetermined portions of the signal lines in one signal layer are aligned relative to and also parallel to corresponding signal lines in the other signal layer, with the power plane being located between these portions. Through hole connections are provided between selected signal lines in the two layers, these occurring through clearance holes in the power plane so as to be isolated therefrom.
