Abstract
A test board is selectively usable as an interface between an integrated circuit device under test (DUT), such as a ball grid array package, and an automatic test equipment (ATE), and as an interface between a calibration apparatus and the ATE. The test board includes a socket, for electrically connecting to the ATE, which includes a plurality of contact terminals which are configured to directly contact terminals of the DUT during a test operation and to directly contact probes of the calibration apparatus during a calibration operation. The test board also includes an alignment mark which is positioned adjacent the socket and which can be sensed by the calibration apparatus during the calibration operation, and a test pad which is positioned adjacent the socket and which is configured to directly contact a test probe of the calibration apparatus for checking an operational state of the calibration apparatus.
