Scanning Acoustic Microscope (SAM), also known as C-SAM or SAT, is a non-destructive testing and imaging device that utilizes ultrasonic waves. It operates by launch ing high-frequency ultrasonic waves into the material being tested. When these waves encounter interfaces between different materials, they experience changes in acoustic impedance due to differences in absorption and reflection properties of the workpiece. By detecting changes in the energy of reflected or transmitted ultrasonic waves, the internal images of the workpiece can be obtained, allowing for the detection of defects such as delaminations, cracks, or voids. SAM is an ideal non-destructive testing method widely used in material testing, failure analysis, quality control, quality assurance, reliability assessment, and research and development. It is particularly effective in detecting defects such as delaminations and cracks in electronic components, LEDs, and metal substrates. The device achieves high detection precision at the micrometer level by comparing the image contrast to identify differences in acoustic impedance within the material, thus determining the shape, size, and orientation of defects.SAM testing can be categorized based on the mode of received information as either reflection or transmission mode, and based on the scanning method, as A-scan, B-scan, C-scan, T-scan, P-scan, focus-scan, and frequency-scan, among others. The Hiwave ultrasonic microscope is advantageous in failure analysis for its non-destructive and non-intrusive capabilities. It can perform layered scans of material or internal structures of IC chips, providin

g intuitive images and facilitating the measurement and statistical analysis of defect size and quantity. A wide range of defects, including cracks, delaminations, inclusions, attachments, voids, and holes, can be detected. Testing involves confirming the sample type, selecting the appropriate frequency probe, placing the sample in the measuring device, choosing the scanning mode, and analyzing the scanned image.Deionized water is used as a medium to transmit ultrasonic signals. When these signals encounter interfaces between different materials, they are partially reflected and transmitted, with the intensity of the returned signals varying due to differences in material density. Scanning acoustic microscopes leverage this characteristic to inspect internal defects of materials and create images based on the changes in the received signals. Application areas of SAM include the semiconductor electronics industry, materials industry, plastic packaging of ICs, wafers, PCBs, LEDs, as well as defects in welds of new energy vehicles" water-cooled plates and battery cell saturation defects.
