Abstract
A method of making an RFID device which includes the steps of (a) applying a UV curable adhesive having electrically conductive particles therein to a pair of laterally displaced landing sites of antenna formed on a UV penetrable web in a manner such that the particles remain spatially positioned from one another, (b) bringing a pair die pads of a die into sufficient electrical contact with the landing sites to effect a Z axis conductivity through the particles between a respective die pad and landing site pad pair while precluding X-Y conductivity between the landing site pads, and (c) UV irradiating of the adhesive through and/or about the web in a manner to cure the adhesive join the die to the antenna. An RFID device is also provided by the process.

A method of making an RFID device which includes the steps of:
- (a) applying a UV curable adhesive having electrically conductive particles therein to a pair of laterally displaced landing sites of an antenna formed on a UV penetrable web in a manner such that said particles remain spatially positioned from one another,
- (b) bringing a pair die pads of a die into sufficient electrical contact with said landing sites to effect a Z axis conductivity through the particles between a respective die pad and landing site pad pair while precluding X-Y conductivity between the landing site pads, and
- (c) UV irradiating of the adhesive in a manner to cure said adhesive joining said die to said antenna.
An RFID device, which includes:
- a UV penetrable substrate;
- an antenna adhered to said substrate having a landing site extending therefrom;
- a die chip having a die pad extending therefrom which is disposed adjacent said antenna;
- and
- a UV cured adhesive having electrically conductive particles dispersed therethrough in a manner to only provide electrical conductivity between said landing site and said die pad, and wherein said adhesive bonds said die chip and said antenna.
