  • System and method for testing packaged devices using time domain reflectometry
    Patent number: 7206703
    Abstract: A test system configured to detect discontinuities in packaged devices. A test unit includes a pulse generator and a sampling circuit. The packaged device is coupled to the test unit via a test fixture. The test unit is configured to transmit a pulse to the packaged device through the test fixture, receive a reflected signal from the packaged device through the test fixture in response to the transmitted pulse, and analyze the reflected signal to detect a discontinuity within the packaged device and/or determine the location of a discontinuity within the packaged device. The test system is configured to store a calibration dataset which includes a set of sample values corresponding to a time domain reflectometry (TDR) test of a calibration packaged device. The test unit is configured to compare data corresponding to the reflected signal to stored values of the calibration dataset to detect a discontinuity in the packaged device.
