Abstract
A beam lead device which has been thermocompressively bonded to a substrate is non-destructively tested to determine the strength thereof by directing a short burst of air at the device and detecting the Stress Wave Emission (SWE) signals emanating from the bond site subsequent to said burst of air. The SWE signals are then processed to determine the strength of the adhesion bond.
