Abstract: An apparatus and method for detecting failed electronics using acoustics. The method comprising directing an acoustic wave toward a circuit component to be tested such that the acoustic wave is reflected off the circuit component, receiving the reflected acoustic wave, amplifying the reflected acoustic wave, and comparing the reflected acoustic wave with known acoustic waves to determine if the circuit component is operating properly. The apparatus comprising a data acquisition system for acquiring data, an X-Y-Z positioner to position two transducers and to hold the circuit component, and software to post-process and analyze the data. The data acquisition system further includes an oscilloscope, a pulser-receiver, two air-coupled transducers, and an amplifier.
