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.

Claims

1. A method of mounting a wire to an inlay substrate for a transponder comprising a substrate, a chip module and an antenna wire disposed on the substrate, said chip module comprising two terminals, the method comprising:

during mounting the wire, ensuring that at least one end portion including an end of the wire is positioned directly over a corresponding at least one terminal of the chip module for subsequent connecting thereto without requiring repositioning;

wherein;

the antenna wire comprises two lengths, or “

stubs”

of wire;

a first of the two stubs of antenna wire is formed by first embedding on the substrate, then causing a first unembedded end portion of the antenna wire to be located directly over a corresponding first one of the two terminals of the chip module;

a second of the two stubs of antenna wire is formed by first embedding on the substrate, then causing a second unembedded end portion of the antenna wire to be located directly over a corresponding second one of the two terminals of the chip module.

2. The method of claim 1, further comprising

connecting the two distal ends of the two stubs of antenna wire together.

3. The method of claim 2, further comprising

connecting the two distal ends of the two stubs of antenna wire together at a capacitor.

4. The method of claim 1, wherein:

the stubs are of unequal length.

5. The method of claim 1, further comprising

subsequently connecting the two unembedded end portions of the antenna wire stubs to the corresponding two terminals of the chip module.
