Abstract
At least some embodiments are directed to a system that comprises storage comprising a data structure that cross-references an identifier of a semiconductor wafer, a location of a die in the wafer, an identifier of a lead frame strip, a location of a lead frame in the lead frame strip, and results of a first test on the die. The system also comprises mechanical equipment configured to test packaged die. The system further comprises a processor, coupled to the storage and to the mechanical equipment, configured to perform a second test on a package containing the die and the lead frame using the mechanical equipment and the results of the first test.
