Scanning acoustic microscopy (SAM) utilizes advanced imaging software and precision motors to transform ultrasonic testing data into easily understandable, high-resolution images of discontinuities in the material being scanned. Ultrasonic testing is based on the transmission of ultrahigh-frequency sound waves through a material. The system measures and interprets the amplitudes and locations of any reflected sound to produce "A-Scan" data, as shown in Fig. 1. "C-Scan" testing maps these A-Scan data to correspond to the areas being tested. The C-Scan imaging technology has been used for decades, but recent advances in software and hardware have increased the capabilities ...
