Patent ID: 8132460

Claim:
A method for inducing a defect in a bond of a bonded article, the method comprising: providing a bonded article having at least two articles, including a first article bonded to a second article, wherein the bond between the first article and the second article has a strength which is substantially in accordance with a full strength specification; applying a pulse of laser energy to a front surface of the first article; inducing a stress wave in the first article such that at least a portion of the stress wave propagates through the first article, the bond, and the second article, and the stress wave at least partially reflects off a back surface of the second article, wherein at least a portion of the reflected stress wave propagates back through the second article to at least the bond and is of sufficient magnitude to induce a defect in the bond; and detecting the defect, wherein the detecting comprises electromagnetically detecting a stress wave signature.
