Abstract
Non-destructive evaluation technique was developed for embedded hardware using hammering inspection with AE (Acoustic Emission) sensor. The integrity of the embedded hardware is judged from both the vibration duration of the embedded hardware recorded by the AE sensor and the frequency analysis of the vibration signal. Mockup tests were carried out in order to verify the effectiveness of the technique and to obtain the diagnostic criteria. The technique was then applied to the field inspection.
