Abstract: The invention relates to a method and a semifinished product for producing a light-emitting diode including: a flexible supporting material; a first and a second contact area, arranged on the supporting material, for producing electrical connections; a light-emitting diode chip or a holder for a light-emitting diode chip, arranged on the supporting material; a foldable flap, formed into the supporting material, the flap being arranged in such a way that it can be folded towards and/or onto the light-emitting diode chip. Arranged on the foldable flap is at least a first electrical connecting web, which is connected to the first contact area and can be connected to a first terminal of the light-emitting diode chip by folding of the flap.

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.
