Power plane

Power plane

In printed circuit board (PCB) design, a power plane is the counterpart to the ground plane and behaves as an AC signal ground, whilst providing DC voltage for powering circuits mounted on the PCB.

Uses

Where possible it is good to have a power plane for each ground plane on a board (known as a "plane pair"), as this reduces power supply impedance to the components on the board.

EDA design tool aspects

In electronic design automation ("EDA") design tools, power planes (and ground planes) are usually drawn automatically as a negative layer. Adding primitives on such a layer produces a negative of those primitives, placing copper wherever there is no track or via.
