D9

A laboratory C-SAM instrument is an acoustic microscope used for non destructive internal inspection. Acoustic microscopy directs high frequency sound into a sample and forms images from returned or transmitted acoustic signals. Laboratory systems of this class are used to reveal hidden delaminations, voids, cracks, bond defects, and other internal features in packaged devices, assemblies, and materials.

C-SAM instruments scan a focused acoustic beam across a sample while recording signal changes caused by interfaces, gaps, and material differences. Reflection imaging emphasizes echoes returning from internal boundaries. Transmission imaging evaluates sound that passes through the sample to highlight features that alter through transmission. Acoustic microscopes typically generate planar images at selected depths so an analyst can inspect buried structures without cutting the sample open.

Laboratory acoustic microscopes are used off line rather than as core patterning or deposition tools in the main process sequence. Such systems commonly sit in analytical labs, failure analysis groups, packaging development areas, and quality organizations that inspect samples drawn from manufacturing or engineering lots. The inspection results can feed back to assembly, bonding, molding, lamination, and other upstream process steps when hidden internal defects are found.

The Sonoscan D9 Series is used for failure analysis, process development, material characterization, and low volume production inspection. The Sonoscan D9 Series is also intended to make scanning larger samples and trays of samples fast, easy, and accurate.^[1]
