ABSTRACT:
In a power supply network network of a printed circuit board, a through hole network for power supply electrically connected to main power supply pads connected with power supply cables is electrically and substantially independent of an internal network comprising networks of power supply layers on the like and a through hold network for load. Thereby, each of source currents supplied from the power supply cables reaches the through hole network for each load, once, via the through hold network for power supply and horizontal buses, therefore the dispersion in the drop of voltage across the main power supply pads and each of the loads is effectively decreased.
