Scanning Acoustic Tomography SAT Testing Services

SAT can detect internal defects including delamination between layers, air voids, cracks, inclusions, and poor adhesive bonding. These defects are often invisible externally but can affect the reliability and performance of electronic or composite components.

SAT testing is widely used in semiconductor, electronics manufacturing, aerospace, automotive, and composite industries. It is particularly useful for inspecting microelectronic packages, circuit boards, and layered materials where internal defects must be detected.

SAT systems typically operate with ultrasonic frequencies ranging from approximately 10 MHz to 300 MHz. Higher frequencies provide improved resolution, enabling detailed imaging of small internal features and microscopic defects.

SAT helps detect hidden internal defects during manufacturing and quality inspection. By identifying issues such as delamination or voids early, manufacturers can prevent product failures and improve long-term reliability of electronic devices.

SAT is a non-destructive testing method that uses high-frequency ultrasonic waves to inspect the internal structure of materials and electronic components. The waves reflect from internal interfaces and defects, and the returned signals are converted into images to identify voids, cracks, and delamination. This method helps assess bonding quality and detect hidden defects without damaging the specimen.
