Abstract:
1. A method for forming a plurality of security tags, said method comprising: providing a first web comprising a plurality of capacitor straps on a first liner, each of said capacitor straps comprising 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 capacitor strap exhibits a desired capacitance, each of said capacitor straps being secured to a first side of a non-conductive layer via an adhesive positioned on an exposed side of said first or second electrically conductive planar elements and on an exposed side of said planar dielectric layer and wherein a second side of said non-conductive layer is releasably secured to said first liner and wherein each of said capacitor straps is separated from adjacent straps; providing a second web of a plurality of antennas or coils on a second liner; indexing said first and second webs so that one of said capacitor straps is aligned with a corresponding one of said plurality of antennas or one of said plurality of coils; and applying selective heat and pressure to each of said capacitor straps to release said capacitor strap from said first liner while electrically connecting said capacitor strap to said corresponding one of said plurality of antennas or of said plurality of coils to form a security tag.
