Claim:
1. A method for attaching a chip to a printed conductive surface, the method comprising: forming the printed conductive surface on a substrate by means of printed electronics to establish at least one conductive pattern on the substrate; heating the chip to a first temperature, which is lower than what the chip and the substrate can stand without being damaged by the heat; and pressing the chip at the first temperature against the at least one conductive pattern established by the printed conductive surface with a first pressing force, wherein a heated roll is configured to transfer heat to the chip during pressing of the chip at the first temperature, and wherein the heated roll presses the chip against the printed conductive surface in a nip between the heated roll and a support roll, wherein a carrier band provides the chip to the nip for disposition on the substrate and wherein the carrier band brings the chip into thermal contact with the heated roll prior to pressing the chip; wherein a combination of said first temperature and said first pressing force is sufficient to at least partly locally melt a material of the at least one conductive pattern established by the printed conductive surface.
