METHOD AND APPARATUS FOR CONTACTLESS TESTING OF RFID STRAPS

摘要

A method and apparatus for batch testing of RFID straps are provided. The RFID straps are arranged on a carrier web in a closely spaced relationship, where each strap includes two terminal pads exposed on the carrier web and an RFID chip. The carrier web is moved so as to align all straps in a batch with corresponding test probes of a test equipment. Each test probe is moved transversely to the moving direction of the carrier web into close proximity with a corresponding strap. A capacitive coupling is established between test electrodes on each test probe and the terminal pads of a corresponding strap. Test signals are then transmitted from each test probe to a corresponding strap, and response signals are received at each test probe from a corresponding strap for evaluation by the test equipment.
