) was imaged from the top side. Gating of the return echoes was at the interface between the molding compound and substrate. Result The large red area is a “popcorn crack

. Gating includes the lead frame, paddle and die surface. Result The unusually symmetrical pattern of the delaminations (red) of the molding compound from the leads is probably caused by incompatible tinning of the leads

. Result Here the acoustic solid has been tilted to achieve a meaningful view. Echoes from the top surface of the package have been retained and appear as the yellow “roof” of the sample
ASYMTEK Products | Nordson Electronics Solutions | https://www.nordson.com/en/divisions/sonoscan/support/application-notes/0306-smart-card-cracked-die
. Result The die in this Smart card has been cracked and the symmetry of the crack suggests that the cracking occurred as a result of improper handling during assembly
