Radio Frequency Identification

Today's RFID tags consist of a graphic overlay and an inlay, with the inlay being the functional part of the tag. Critical to the assembly of the tags and their robust in-field performance is the selection of adhesives used to construct these devices. Adhesive materials are used to attach dies onto antenna to build the inlays, which can be constructed either by usig an interconnect adhesive to attach a small bare die directly to an antenna, or using an interconnect adhesive to build a much larger packaged die.

Used for everything from toll booths to department store inventory control, Radio Frequency Identification (RFID) tags are devices capable of uniquely identifying an object via a pre-programmed response when queried by an external radio frequency wave.
