SAM, The Preferred Method For The Non-Destructive Internal Inspection. Scanning Acoustic Microscopy of COTS and plastic encapsulated microelectronics. Confocal Scanning Acoustic Microscopy (C-SAM) has proved to be the most effective non-destructive approach for the screening of COTS parts and the detection of latent internal anomalies in PEMs, either before soldering or for assembled systems.
