Patent Images
1. A method for assembling a plurality of radio frequency identification (RFID) tags, comprising:
- (a) applying an underfill material on a surface of a substrate structure having an array of tag substrates;
(b) positioning a support surface closely adjacent to the surface of the substrate structure, such that each die of a plurality of dies attached to a first surface of the support surface is closely adjacent to a corresponding tag substrate of the array of tag substrates; and
(c) simultaneously transferring each die of the plurality of dies onto the closely adjacent corresponding tag substrate from the support surface.
