Scanning Acoustic Microscopy (SAM)
Scanning acoustic microscopy (SAM) uses sound waves to detect and identify internal delamination, voids, material density changes, defects and many other anomalies within devices, assemblies and materials.
SAM is highly sensitive to the presence of delamination and material density variations, which are difficult to detect using X-ray radiography, Infrared Imaging and other non-destructive techniques. It can detect sub-micron air gaps and has a defect resolution of ~5µm.
EAG offers various imaging modes, allowing the operator to gain the optimal viewing perspective based on the orientation of the feature within the sample. In addition, EAG’s SAM systems incorporate advanced software, hardware features and a wide variety of transducers which allows EAG to provide our customers with the best imaging on the market.
