Patent ID: 8451615

Claim:
A printed circuit board (PCB) comprising: a top layer; a power supply and an electronic component separately mounted on and electrically connected to the top layer; a bottom layer; and at least one first vertical interconnect access (via) extending through the top layer and the bottom layer, to electrically connect the power supply to the bottom layer; and a plurality of second vias extending through the top layer and the bottom layer and electrically connected to the top layer and the bottom layer, wherein a right-angled triangular void area without vias defined therein is formed on the PCB, between the plurality of second vias and the electronic component, the plurality of second vias is arranged on a hypotenuse of the void area, and paths of current flowing from the plurality of second vias to the electronic component are substantially perpendicular to the hypotenuse of the void area, such that the plurality of second vias substantially evenly divides the current to prevent over-heating of the plurality of second vas.
