Abstract: A method for the self-assembly of at least one electrical, electronic or micromechanical component on a substrate, including the steps of: a) providing the substrate, b) applying an adhesive-repelling composition to at least one partial surface of the substrate which does not constitute a target position of the component, followed by a curing step, c) applying an adhesive composition to at least one partial surface of the substrate which constitutes a target position of the component, the partial surface of the substrate which is provided with the adhesive-repelling composition enclosing and adjoining the partial surface of the substrate which is provided with the adhesive composition, and d) applying at least one component to a partial surface coated in accordance with b) or c), in which method the adhesive-repelling composition is a radiation-curing abhesive coating compound, and to an electrical or electronic product which can he produced according to the method.
