Abstract

A probe card for integrated circuit testing includes a printed circuit support and a probe head having a first surface mounted to a surface of the printed circuit support. A flexible substrate is positioned adjacent to a second surface of the probe head and includes at least one flexible extension which extends beyond an edge of the probe head and includes a bend to make contact with the surface of the printed circuit support. The flexible substrate further includes a test antenna configured to support a wireless communications channel with an integrated circuit under test. The integrated circuit under test includes at least one conductive structure that extends in the peripheral portion on different planes of metallizations to form an integrated antenna that is coupled for communication and/or power transfer to the test antenna.
