Transferring an antenna to an RFID inlay substrate
First Claim
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.

Abstract
Forming antenna structures having several conductor turns (wire, foil, conductive material) on a an antenna substrate (carrier layer or film or web), removing the antenna structures individually from the antenna substrate using pick & place gantry or by means of die punching, laser cutting or laminating, and transferring the antenna structure with it'"'"'s end portions (termination ends) in a fixed position for mounting onto or into selected transponder sites on an inlay substrate, and connecting the aligned termination ends of the antenna structure to an RFID (radio frequency identification) chip or chip module disposed on or in the inlay substrate. A contact transfer process is capable of transferring several antenna structures simultaneously to several transponder sites.
