ABSTRACT:
A system for identifying probe cards including a prober which accepts a number of interchangeable probe cards, each carrying a transponder tag; a magnetic coupling antenna supported above the probe card when it is in use, the transponder tag being substantially located within a magnetic field generated by the magnetic coupling antenna; and circuitry connected to the magnetic coupling antenna for receiving signals emitted by the transponder tag, for deriving data therefrom, and for communicating the data to a central computer which holds information on the probe cards in a memory.
