Transfer tape strap process
View Patent ↗A method for efficiently producing a plurality of EAS or RFID tags or inlays that form a label ready for use. The process utilizes a first web of RFID chip straps or capacitor straps that are releasably secured to a liner using only a low tack adhesive and utilizes a second web of coils or antennas which are secured to a second liner. After indexing these two webs, selective heat and pressure are applied to the chips straps or to the capacitor straps to transfer them and electrically couple them to a corresponding coil or antenna. Where both chip straps and capacitor straps are applied to a common antenna, a third web of the additional strap is used in the process.
1. A web of strap components for forming an EAS or RFID inlay, said web comprising:
a plurality of strap components that are releasably secured to a web liner portion but are separated from adjacent strap components;
wherein each of said strap components comprises a thin, generally planar member comprising a first electrically conductive planar element, a second planar electrically conductive element and a planar dielectric layer disposed between at least portions of said first and second electrically conductive planar elements, whereupon said strap component exhibits a desired capacitance, said first electrically conductive planar element and said second planar electrically conductive element being secured to a first side of a non-conductive layer and wherein a second side of said non-conductive layer is releasably secured to said web liner portion; and
wherein said first electrically conductive planar element comprises an exposed side having an adhesive disposed thereon and wherein said planar dielectric layer comprises an exposed side having an adhesive disposed thereon, said adhesive being used to secure said strap component to an antenna or coil to form said EAS or RFID inlay.
2. The web of claim 1 wherein said second side of said non-conductive layer is releasably secured to said liner using a low tack adhesive.
