Method of connecting an antenna wire to a transponder chip. A transponder chip 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 into the recess from the same side as the antenna. The end portions may then be repositioned to be over corresponding terminals of the chip, for bonding thereto. The recess may be substantially larger than the chip, so that the chip and/or the substrate may be moved from side-to-side in the recess for positioning the terminals under the end portions, for bonding thereto. Insulation may be removed from the end portions prior to mounting the chip in the recess, to enhance subsequent bonding.

What is claimed is: 1. Method of connecting an antenna wire to a transponder chip comprising: providing a recess in a surface of a substrate; mounting the antenna wire to the surface of the substrate so that two end portions of the antenna wire span the recess; characterized by: the end portions of the antenna wire are spaced a distance apart from one another which is greater than a width dimension of the transponder chip; after the antenna wire is mounted to the surface of the substrate, inserting the transponder chip into the recess, past the two end portions of the antenna wire, wherein the two end portions of the antenna wire form wire bridges on each side of the transponder chip; and subsequently repositioning the end portions so that the two end portions of the antenna wire are located directly over corresponding two terminals of the transponder chip; further comprising: providing slots under the end portions of the antenna wire to allow the end portions to be gripped for repositioning. 2. The method of claim 1, further comprising: interconnecting the two end portions of the antenna wire to the corresponding two terminals of the transponder chip. 3. The method of claim 1, wherein: the chip has a width dimension; and the recess has a width dimension which is significantly greater than the width dimension of the chip, including at least 20% greater, at least 25% greater, at least 30% greater, at least 40% greater, at least 50% greater, at least 60% greater. 4. Method of connecting an antenna wire to a transponder chip comprising: providing a recess in a surface of a substrate; mounting the antenna wire to the surface of the substrate so that two end portions of the antenna wire span the recess; characterized by: the end portions of the antenna wire are spaced a distance apart from one another, wherein the distance is greater than a width dimension of the transponder chip; disposing the transponder chip in the recess after the antenna wire is mounted to the surface of the substrate; repositioning at least one of the end portions so that the two end portions are located directly over corresponding two terminals of the transponder chip; imparting a first relative motion between the chip and the substrate so that the first terminal of the chip is positioned under the first end portion of the wire, and bonding the first end portion of the wire to the first terminal of the chip; and imparting a second relative motion between the chip and the substrate so that the second terminal of the chip is positioned under the second end portion of the wire, and bonding the second end portion of the wire to the second terminal of the chip. 5. The method of claim 4, further comprising: imparting a third relative motion between the chip and the substrate to center the chip in the recess. 6. The method of claim 4, wherein: the first and second relative motions are imparted by moving the chip relative to a stationary substrate. 7. The method of claim 4, wherein: the first and second relative motions are imparted by moving the substrate relative to a stationary chip. 8. The method of claim 4, further comprising: removing insulation from the wire prior to bonding. 9. The method of claim 4, wherein: the chip has a width dimension; and the recess has a width dimension which is significantly greater than the width dimension of the chip, including at least 20% greater, at least 25% greater, at least 30% greater, at least 40% greater, at least 50% greater, at least 60% greater. 10. The method of claim 4, further comprising: interconnecting the two end portions of the antenna wire to the corresponding two terminals of the transponder chip. 11. Method of connecting an antenna wire to a transponder chip comprising: providing a recess in a surface of a substrate; mounting the antenna wire to the surface of the substrate so that two end portions of the antenna wire span the recess; disposing the transponder chip in the recess, between the two end portions of the antenna wire; and imparting at least one relative motion between the chip and the substrate so that a first terminal of the chip is positioned under a first of the two end portions of the wire for bonding thereto and so that a second terminal of the chip is positioned under a second of the two end portions of the wire for bonding thereto; further comprising: providing slots under the end portions of the antenna wire to allow the end portions to be gripped for repositioning. 12. The method of claim 11, further comprising: interconnecting the two end portions of the antenna wire to the corresponding two terminals of the transponder chip. 13. The method of claim 11, further comprising: using a wire gripper to reposition the end portions of the antenna wire. 14. The method of claim 11, further comprising: removing insulation from at least the end portions of the wire prior to bonding. 15. The method of claim 11, wherein: the transponder chip has a width dimension; and the recess has a width dimension which is significantly greater than the width dimension of the transponder chip, including at least 20% greater, at least 25% greater, at least 30% greater, at least 40% greater, at least 50% greater, at least 60% greater. 16. The method of claim 11, wherein: the substrate comprises a multi-layer substrate. 17. Method of connecting an antenna wire to a transponder chip comprising: providing a recess in a surface of a substrate; mounting the antenna wire to the surface of the substrate so that two end portions of the antenna wire span the recess; disposing the transponder chip in the recess, between the two end portions of the antenna wire; and imparting at least one relative motion between the chip and the substrate so that a first terminal of the chip is positioned under a first of the two end portions of the wire for bonding thereto and so that a second terminal of the chip is positioned under a second of the two end portions of the wire for bonding thereto; wherein: the relative motion is imparted by moving the chip relative to a stationary substrate. 18. The method of claim 17, wherein: the substrate comprises a multi-layer substrate. 19. Method of connecting an antenna wire to a transponder chip comprising: providing a recess in a surface of a substrate; mounting the antenna wire to the surface of the substrate so that two end portions of the antenna wire span the recess; disposing the transponder chip in the recess, between the two end portions of the antenna wire; and imparting at least one relative motion between the chip and the substrate so that a first terminal of the chip is positioned under a first of the two end portions of the wire for bonding thereto and so that a second terminal of the chip is positioned under a second of the two end portions of the wire for bonding thereto; wherein: the relative motion is imparted by moving the substrate relative to a stationary chip. 20. The method of claim 19, wherein: the substrate comprises a multi-layer substrate.
