Abstract
As leads that have been thermocompressively bonded to ceramic substrates are pulled to destruction, stress waves are monitored and counted. The total count is compared to empirically developed ranges associated with known failures to determine the failure mode (e.g., lead failure, gold-to-gold failure, ceramic pullout).
