Unreasonable attempt to interfere with the printed circuit board ground design, not up to design requirements, or even does not work. Ground is the electric potential reference point in the circuit, and current public access. Potential theory is a zero-potential, but due to wire resistance exists, all parts of the ground potentials are not zero. Because the ground is not a zero everywhere as long as there is a certain length the equipotential point, ground is not only essential to circuit public channel, interference is one of the channels.
