Abstract
In a method of coating substrates, especially printed circuit boards, on both sides, one side of the substrate, which is provided with holes, is coated by a coating process, especially by screen printing, wherein the holes that are not required for the circuit layout are lastingly covered over and the holes that are required are covered over only slightly or are left clear, whereupon the other side of the substrate is coated by a coating process, especially by curtain pouring or spraying, wherein the entire surface of the substrate is provided uniformly with a coating that gives only a light covering over the holes.
