An apparatus and method for attaching antennae to RFID tags is disclosed.
Included is the use of RFID tags having a symmetrical interconnect system
for attaching one or more antennae, such that virtually any rotational
orientation of the RFID tag will result in a successful antennae
attachment. Two oversized and "L" shaped gold-bumped poles can be
arranged on the same side of a chip in an opposing fashion, such that at
least one axis of symmetry is formed. Accordingly, virtually all
rotational orientations of the chip are then acceptable when attaching a
pair of opposing pole antenna leads. Alternatively, a pair of poles can
be located on opposing chip surfaces, such that antenna substrates can
attach to both the top and bottom of the chip to form a product
"sandwich," whereby the rotational orientation of the chip is irrelevant
at an antenna attachment step.
