An Infra-red led emitter is inspected by scanning acoustic microscopy. Probe frequency is adapted to the characteristics of the system. In this case, considering the large thickness of the package a 50 MHz transducer is used. Our phase inversion algorithm identifies and highlights the delaminated areas. In addition, A-scan inspection is used to confirm these findings.
