  • Patent number: 7884726
    Abstract: 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.

  • Patent number: 7820481
    Abstract: A rotary chip attach process and manufacturing approach takes chips (e.g., integrated circuits (ICs)) from a wafer in a rotary process. A chip wafer with a positioning unit is placed over the top of a sprocketed wheel that picks the ICs directly from the wafer and moves them in a semi-continuous in-step motion to a web that will accept the ICs. The sprocketed wheel includes chips that are preferably the same type as used in a typical pick-and-place robotic system, with vacuum heads adapted to pierce the wafer flat membrane (if needed), grab and IC and place and IC as desired. This positioning system keeps the IC's placement in an accurate position on the web, which can be made to move continuously with a plurality of sprocketed wheel placement units in place.

  • Patent number: 7621043
    Abstract: A poly sheet continuously moving in a machine direction is heated to a temperature just below its glass thermal temperature to make the poly malleable. A circuit (e.g., RFID chip, EAS chip, transponder, IC) is placed on the poly sheet and embedded into the poly sheet, preferably with a heat resistant soft (e.g., rubber) roller that presses the circuit into the poly without breaking the circuit. A conductive strip or wire may be applied on or into the poly sheet to align with connection points (e.g., conductive bumps) of the circuit for conductive communication with the circuit. The conductive strip or wire is preferably cut to form gaps that are nonconductive between the cut sections of wire to avoid shorting of the circuit and/or allow the conductive strip or wire to function as an antenna for the circuit, and thus to form a chip strap or tag. The poly sheet thus provides a protective womb or shield for the circuit and wire.

  • Patent number: 7497004
    Abstract: A method of making UHF antennas for security tag and antennas thereby. A web of electrically conductive material having a thickness in the range of approximately 5 to approximately 50 microns is releasably secured to a carrier web using a releasably securable adhesive substantially coextensive with the conductive web. A series of antennas of a desired shape are die-cut into the conductive web, but not into the carrier web. The portion of the conductive web not making up the antennas is in the form of scrap and is removed, thereby leaving the series of antennas releasably secured to the carrier sheet. The antennas are arranged to be removed from the carrier sheet, whereupon the releasably securable adhesive is transferred to them, so that they may be subsequently secured to other components to form a security tag.

  • Patent number: 7450011
    Abstract: The invention is directed to a security tag (7?) for protecting an article (1) against theft, with an electronically detectable first security element (3) and a covering layer (4) covering said first security element completely. The covering layer (4) is covered completely with a label (6) made of tearable material, which on its side facing the covering layer (4) is provided with an adhesive whose bonding strength is at least somewhat lower than that of the adhesive applied to the covering layer (4). Arranged between the covering layer (4) and the label (6) is a second security element (5), which overlaps the covering layer (4) at least in part and is provided on its side facing the covering layer (4) with an adhesive whose bonding strength is somewhat greater than that of the adhesive applied to the label (6). The covering layer (4) and the second security element (5) are completely covered by the label (6).

  • Publication number: 20070102486
    Abstract: A wire embedded bridge made by the apparatus and method disclosed by example herein may be commonly used for the formation of an RFID circuit or chip strap. The process uses flexible polyester and/or other films as a base component of the bridge. A wire is heated and embedded into the poly sheet at precise locations in a continuous process, for example, with the poly continuously moving in a machine direction. The locations of the wire make chip placement onto the wire track reliable and inexpensive, preferably using heat and pressure to bond the chips with the embedded wire and form a protected RFID circuit.

  • Patent number: 7144470
    Abstract: This invention concerns a process and a device for producing strip elements for electronically securing articles and a corresponding produced strip element. The aim of the invention is to present a process, a device, and a strip element which can be economically produced according to said process. As for the process, the aim is achieved in that an endless strip of electronically detectable material is fed and is cut into individual segments of a defined length, in that the individual segments are advanced by means of a conveyor, the speed of which is greater than the speed at which the endless strip is fed, the relative velocity being adjusted to provide the desired interval between two consecutive strip segments, and in that the segments separated by intervals are given a coating on one or both sides.
