A system and method for increasing the wiring channels/density under dense via fields of a circuit board are provided. With the system and method, the power/ground lines for the circuit board are designed to be provided in an orthogonal or diagonal pattern. The land grid array (LGA)/ball grid array (BGA) makes contact only on the surface pads of the printed circuit board with no plated through holes/vias underneath these surface pads. This opens up wiring channels, which previously used to be occupied by plated through holes and anti-pads, that can now be used for maximizing signal line wiring routing.
