A printed circuit board assembly has a first printed circuit board with first and second surfaces, a plurality of electrical contact pins which pass through the first printed circuit board, wherein first ends of the contact pins are electrically contacted on the second surface by soldered elevations, and with first electrical contacts which are arranged on the second surface; and a second printed circuit board with first and second surfaces in which a plurality of blind holes are formed for receiving the first ends of the contact pins, wherein the second printed circuit board has second electrical contacts on the second surface, and the second surfaces of the first printed circuit board and the second printed circuit board are joined together such that the contact pins reach into the blind holes such that the first electrical contacts electrically contact the second electrical contacts.
