Abstract
A system and method for evaluating wafer test probe cards under real-world wafer test cell condition integrates wafer test cell components into the probe card inspection and analysis process. Disclosed embodiments may utilize existing and/or modified wafer test cell components such as, a head plate, a test head, a signal delivery system, and a manipulator to emulate wafer test cell dynamics during the probe card inspection and analysis process.
