Scanning Acoustic Microscopes (SAM) are advanced devices that utilize focused sound waves to investigate, measure, or image objects. This technique, known as scanning acoustic tomography, is widely used in failure analysis and non-destructive evaluation. SAMs are particularly valuable in industries like microelectronics, where they help detect voids, cracks, and delaminations within microelectronic packages. Applications of SAM extend to various fields, including biological and medical research, aerospace, automotive, and materials analysis. Its ability to provide detailed internal images makes it an essential tool for ensuring the quality and reliability of critical components.
