Design of a two interconnect IC chip for a radio frequency identification tag and method for manufacturing same
First Claim
1. A radio frequency identification system, comprising:
- an antenna arrangement having a plurality of traces adapted to be attached to a plurality of RFID poles; and
an RFID package including a radio frequency identification integrated circuit and a plurality of exposed poles arranged thereupon, wherein at least two of said plurality of traces on said antenna arrangement are directly and operatively attached to at least two of said plurality of exposed poles respectively, whereby said plurality of exposed poles are configured such that at least two of said plurality of antenna traces can be directly and operatively attached to at least two of said plurality of exposed poles when said RFID package is in any of at least three distinct rotational positions with respect to said antenna arrangement.

Abstract
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.
