Abstract
A method for attaching antennae to RFID tags is disclosed. Included is the use of RFID tags having asymmetrical interconnect system for 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 holes can be arranged on the same side of the ship in an opposing action, 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 chips surfaces, such that antenna substrates can be attached 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.
