| 1. An electronic device comprising:
at least one IC strap; and
a conductor pattern coupled to the IC strap, said conductor pattern having at least a pair of inductors formed by a first
inductor electrically connected to a second inductor, said first and second inductors arranged in a pattern so that a misplacement
of said IC strap relative to said conductor pattern causes a change in said first inductor to compensate for a change in said
second inductor.
