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 cutting or nicking the wire. Insulation may be removed from a portion of 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.

First claim

What is claimed is:

1. A sonotrode for mounting an antenna wire to an inlay substrate for a transponder, comprising:
a capillary having a supply end, a delivery end, and an internal bore through which the wire passes;
a clamping mechanism for holding the wire relative to the capillary;
a cutting mechanism for at least partially severing the wire;
wherein:
the cutting mechanism is disposed before the capillary.

2. The sonotrode of claim 1 , wherein:
the clamping mechanism is disposed before the capillary.

3. The sonotrode of claim 1 , wherein:
the cutting mechanism is disposed between the capillary and the clamping mechanism.

4. The sonotrode of claim 1 , further comprising:
means for removing insulation from the wire where it is partially severed.

5. The sonotrode of claim 1 , wherein:
the cutting mechanism severs the wire.

6. The sonotrode of claim 1 , further comprising:
a laser for removing insulation from the wire.

7. The sonotrode of claim 6 , wherein:
insulation is removed from the wire either above or below the cutting mechanism.
