Abstract:
1. A method of forming a transponder site comprising an inlay substrate, an RFID chip module and an antenna structure connected to the chip module comprising: preparing a plurality of transponder sites on an inlay substrate, each transponder site comprising a defined area of the inlay substrate; forming a plurality of antenna structures on an antenna substrate which is separate from the inlay substrate; and removing given antenna structures from the antenna substrate and transferring them to selected ones of the transponder sites; wherein removing the antenna structures comprises: causing antenna structures to be released from the antenna substrate using one or more of the processes selected from the group consisting of: applying a mechanical force to the antenna substrate; directing a laser beam at the antenna substrate; heating a portion of the antenna substrate; softening a portion of the antenna substrate; distorting a portion of the antenna substrate; causing a temperature differential between the antenna substrate and the inlay substrate; bringing the antenna substrate and the inlay substrate into face-to-face contact with one another; selecting physical properties of the antenna substrate and inlay substrate to facilitate release of the antenna structures from the antenna substrate onto the inlay substrate; and performing a laminating process.
