RFID label with release liner window, and method of making
First Claim
1. A method of making an REID label, the method comprising:
- forming an antenna on a substrate;
applying an adhesive over at least part of the antenna;
after applying the adhesive, coupling an interposer to the antenna, wherein the interposer includes a chip and conductive interposer leads coupled to the chip;
testing performance of the interposer before coupling the interposer to the antenna; and
adhering a release liner to the adhesive.

Abstract
An RFID label includes a release liner having an opening or window, to allow placement of an interposer through the window, and in contact with end portions of an antenna. By coupling the interposer to the antenna through the window in the release liner, the coupling may be performed at a later point than usual in the fabrication of the label. This allows the label to be fabricated with less wear and tear on the interposer, which is a relatively expensive and fragile part of the antenna. In addition, testing of the interposers before applying them to a web of labels may save costs by eliminating waste of material. Testing of the straps alone can allow prediction of performance of the finished label.

17. An RFID label comprising:
-
a substrate; an antenna on the substrate; a patterned adhesive overlying at least pan of the antenna and the substrate wherein the patterned adhesive has an open area leaving at least pans of the antenna ends uncovered by adhesive; an interposer coupled to antenna ends of the antenna and the interposer is also adhesively coupled to pans of the patterned adhesive; a release liner adhered to the adhesive; a conductive adhesive that couples interposer leads of the interposer to the antenna ends; wherein the release liner has an opening therein in which the interposer is located and the release liner opening is larger than the patterned adhesive open area. - View Dependent Claims (18, 19)
