Attaching an electronic circuit to a substrate

A method of attaching an electronic circuit to a substrate, comprising:

• providing an electronic circuit having at least two electrical terminals;
• securing the electronic circuit to the substrate;
• applying a conductive element to the substrate and the electronic circuit to define an antenna, so that the conductive element makes electrical contact with the at least two electrical terminals;
• and
• applying a protective coating over the electronic circuit and at least a portion of the antenna, wherein the protective coating comprises a layer of settable sealant.

A method of attaching an integrated circuit to a substrate, comprising:

• providing an integrated circuit having at least two electrical terminals, wherein the electronic circuit comprises a transponder which is programmable with an identity code;
• securing the integrated circuit to the substrate;
• applying a conductive element to the substrate and the integrated circuit to define an antenna, so that the conductive element makes electrical contact with the at least two electrical terminals;
• applying at least one contact element to the substrate which is in contact with a terminal of the transponder;
• applying contacts of a programming device to the antenna and the at least one contact element after securing the integrated circuit and the antenna to the substrate to program the identity code into the transponder;
• and
• applying a protective coating to the transponder, a portion of the antenna and a portion of the contact element prior to programming of the transponder, wherein the contacts of the programming device are applied to uncoated portions of the antenna and the contact element.

A method of attaching an electronic circuit to a substrate comprising:

• providing an electronic circuit having at least two electrical terminals;
• securing the electronic circuit to the substrate;
• and
• applying a metallic foil layer to the substrate and the electronic circuit to define an antenna, so that the metallic foil layer makes contact with the at least two electrical terminals.

A method of attaching an electronic circuit to a substrate comprising:

• providing an electronic circuit having at least two electric terminals;
• providing an indentation in the substrate;
• inserting the electronic circuit into the indentation;
• securing the electronic circuit to the substrate;
• and
• applying a conductive element to the substrate and the electronic circuit to define an antenna, so that the conductive element makes electrical contact with the at least two electrical terminals.
