Abstract

In an embodiment, a method for assembling an RFID device is disclosed. In the embodiment, the method involves placing an adhesive on an antenna structure of an RFID device, the antenna structure including a substrate, an antenna formed on the substrate, the antenna having a first end and a second end that are separated, placing an integrated circuit (IC) device on the adhesive such that the first end of the antenna is electrically coupled to the second end of the antenna via the IC device, and applying a trigger to at least one of the first end and the second end of the antenna to cause the antenna to become heated, which causes the adhesive to cure.

First claim

What is claimed is:

1 . A method for assembling an RFID device, the method comprising:
placing an adhesive on an antenna structure of an RFID device, the antenna structure including:
a substrate;
an antenna formed on the substrate, the antenna having a first end and a second end that are separated;
placing an integrated circuit (IC) device on the adhesive such that the first end of the antenna is electrically coupled to the second end of the antenna via the IC device; and applying a trigger to at least one of the first end and the second end of the antenna to cause the antenna to become heated, which causes the adhesive to cure.

2 . The method of claim 1 , wherein the trigger is applied from a single direction.

3 . The method of claim 1 , wherein heat from the antenna is delivered from under the IC device.

4 . The method of claim 1 , wherein applying the trigger comprises applying electrical current to the antenna.

5 . The method of claim 1 , wherein applying the trigger comprises applying a laser beam to the antenna.

6 . The method of claim 1 , wherein applying the trigger comprises applying infrared light to the antenna.

7 . The method of claim 1 , wherein applying the trigger comprises applying a heat thermode to the antenna.

8 . The method of claim 1 , wherein applying the trigger comprises applying microwaves to the antenna.

9 . The method of claim 4 , wherein applying electrical current to the antenna comprises applying an electrode to each end of the antenna to apply a voltage across the antenna.

10 . A method for assembling an RFID device, the method comprising:
placing an adhesive on an antenna structure of an RFID device, the antenna structure including:
a substrate;
an antenna formed on the substrate, the antenna having a first end and a second end that are separated;
placing an integrated circuit (IC) device on the adhesive such that the first end of the antenna is electrically coupled to the second end of the antenna via the IC device; and applying heat to at least one of the first end and the second end of the antenna to cause the antenna to become heated, which causes the adhesive to cure.

11 . The method of claim 10 , wherein the trigger is applied from a single direction.

12 . The method of claim 10 , wherein heat from the antenna is delivered from under the IC device.

13 . A method for assembling an RFID device, the method comprising:
placing an adhesive on an antenna structure of an RFID device, the antenna structure including:
a substrate;
an antenna formed on the substrate, the antenna having a first end and a second end that are separated;
placing an integrated circuit (IC) device on the adhesive such that the first end of the antenna is electrically coupled to the second end of the antenna via the IC device; and applying a trigger in a single direction from under the IC device to at least one of the first end and the second end of the antenna to cause the antenna to become heated, which causes the adhesive to cure.

14 . The method of claim 13 , wherein applying the trigger comprises applying electrical current to the antenna.

15 . The method of claim 13 , wherein applying the trigger comprises applying a laser beam to the antenna.

16 . The method of claim 13 , wherein applying the trigger comprises applying infrared light to the antenna.

17 . The method of claim 13 , wherein applying the trigger comprises applying a heat thermode to the antenna.

18 . The method of claim 13 , wherein applying the trigger comprises applying microwaves to the antenna.
