Abstract:
1. A method of producing a transponder, the method comprising: providing a substrate which comprises a first area, a second area adjacent to said first area, and a first surface electrical contact being attached on said substrate adjacent to said second area, and a third area adjacent to said first area, and a second surface electrical contact attached on said substrate adjacent to said third area, each of the second area and the first surface electrical contact being adjacent to neither the third area nor the second surface electrical contact; conditioning said substrate such that said first area has a first wettability, said second area has a second wettability and said third area has a third wettability, said first wettability being lower than said second and said third wettability; placing an electrical device in or on said first area, wherein said electrical device has a lower surface, an upper surface and a plurality of side surfaces, at least one of which comprises electrical contacts; and applying a conductive glue on said second and third areas and/or on said first surface electrical contact and said second surface electrical contact so that said conductive glue automatically centers the electrical device and electrically couples said first and said second surface electrical contacts with to said electrical contacts of said electrical device.
