Abstract
A method is described for the manufacture of structured flexible metallic patterns in which a metallic layer on a flexible substrate is structured using laser ablation. The flexible patterns manufactured in this fashion may be used as interposers (strap) for RFID tags or RFID antennas.
Claims23
A method of making a RFID component comprising the acts of
- a. providing a web, wherein said web comprises an insulating substrate having a conductive coating;
- b. exposing a portion of said web to a laser beam, whereby a first structure is formed in said conductive coating, said first structure having a first predetermined geometric shape, said first geometric shape having predetermined features, said features having predetermined dimensions;
- and
- c. moving said web relative to said laser beam wherein a second portion of said web is exposed to said laser beam, whereby a second structure is formed on said second portion, said second structure having a second geometric shape, said second geometric shape being substantially similar to said first geometric shape, said first structure and said second structure when compared to each other for similarity have a tolerance within 3 microns.

The method of 17, wherein a tie coat is sandwiched between said metallic coating and said insulating substrate.
A method of making a RFID component comprising the acts of
- a. providing a web, wherein said web comprises an insulating substrate having a conductive coating;
- b. exposing a portion of said web to a laser beam, said laser beam being produced by a pulsed Excimer laser, whereby a first structure is formed in said conductive coating, said first structure having a first predetermined geometric shape, said first geometric shape having predetermined features, said features having predetermined dimensions;
- and
- c. moving said web relative to said laser beam wherein a second portion of said web is exposed to said laser beam, whereby a second structure is formed on said second portion, said second structure having a second geometric shape, said second geometric shape being substantially similar to said first geometric shape.
