Abstract

The objective of the presented work was enhancement of quality of ultrasonic images of electronic components, obtained by the pulse-echo ultrasonic technique. For this purpose a novel signal processing method based on the adaptive ultrasonic numerical model of the electronic device and selection of the appropriate time and frequency regions has been proposed
