Abstract:
Method of connecting an antenna wire to a transponder chip. A transponder chip or chip module in a recess in a substrate, and an antenna wire mounted to the surface of the substrate and having end portions spanning the recess. The end portions are spaced wider than the chip, to allow the chip to be inserted (installed) into the recess from the same side as the antenna past the end portions of the antenna wire. The chip may be moved in the recess so that its terminals are under the wires, or the wires may be repositioned to be over the terminals, for subsequently bonding thereto. Prior to installing the chip in the recess, insulation may be removed from the end portions of the antenna wire, which may also be flattened to improve bonding.
Abstract:
Microstructures such as connection areas, contact pads, antennas, coils, plates for capacitors and the like may be formed using nanostructures such as nanoparticles, nanowires and nanotubes. A laser may be used to assist in the process of microstructure formation, and may also be used to form other features on a substrate such as recesses or channels for receiving the microstructures.

Abstract:
Forming antenna structures having turns of wire, foil or conductive material on a an antenna substrate or in a layer of adhesive layer on a carrier substrate, transferring the antenna structures individually or many at once to corresponding transponder sites on an inlay substrate and connecting the aligned termination ends of the antenna structures to terminal areas of RFID chip modules at the transponder sites. Transferring may be performed by various means such as laminating (heat and pressure), or heating the antenna structures directly or indirectly. The antenna substrate may be in web format or sheet format. Automated manufacturing procedures are disclosed. Kits having components for manufacturing inlay substrates, inlays and secure documents are disclosed. Various features of an inlay substrate and chip module are disclosed.

Abstract:
A method and apparatus are provided for making radio frequency (RF) inlays. The RF inlays include an integrated circuit and an antenna affixed to a substrate material carrying the integrated circuit. During processing, portions of the wire forming the antenna are located adjacent to, but not directly over the integrated circuit. In the subsequent processing step, the wire ends are placed in contact with and secured to the integrated circuit terminal areas.
Abstract:
During mounting to an inlay substrate, at least one end portion (including end) of an antenna wire is positioned directly over a terminal of the chip module for subsequent connecting thereto. A sonotrode is disclosed with a cutter above the capillary for nicking the wire. The antenna may comprise two separate stubs, each having an end portion (including end) positioned over a terminal of the chip module. Additional techniques for mounting the antenna wire are disclosed.
Abstract:
Forming an inlay comprising an antenna wire having two end portions and a site for a transponder chip, comprises: mounting the wire to a surface of substrate; and leaving the end portions of the antenna wire free-standing, as loops adjacent terminal areas of a site on the substrate for the transponder chip. With the transponder chip installed on the substrate, the free-standing loops are repositioned to be substantially directly over the terminals of the transponder chip, in preparation for interconnection of the loops to the terminals of the transponder chip, then are bonded to the terminals. An embedding tool for mounting the wire on the substrate may embed the wire in or adhesively place a self-bonding wire on a surface of the substrate. The substrate may have two transponder chips, and function as a secure inlay. An anti-skimming feature is included in the inlay.
Abstract:
A method and apparatus are provided for making radio frequency (RF) inlays. The RF inlays include an integrated circuit and an antenna affixed to a substrate material carrying the integrated circuit. During processing, portions of the wire forming the antenna are located adjacent to, but not directly over the integrated circuit such that the wire may be subject to further processing, such as removing insulation without potentially damaging the integrated circuit. In the subsequent processing step, the wire ends are placed in contact with and secured to the integrated circuit terminal areas. Methods of the invention include forming loops with the wire ends wherein the loops extend above a plane of the substrate, and in another processing step, the loops are displaced to be electrically connected to the terminal areas. Methods also include repositioning the wire and using a brush or comb device.
