Abstract: A printed circuit board having a generally box-like carrier plate with a top side and an underside. The board has at least first and second conductor track plane separated by a first distance and an electrical circuit which occupies at least one section of the carrier plate. The section contains a screen for protecting the circuit from electromagnetic interference. The screen has a first screening conductor track which is arranged on the first conductor track plane and surrounds the section, and a second screening conductor track which is arranged on the second conductor track plane and also surrounds the section. The first and second screening conductor tracks are congruent at least in a circumferential region which surrounds the circuit. The screen has, in the circumferential region, a plurality of plated-through holes which penetrate the carrier plate and connect the first and second screening conductor tracks.
