Ultrasonic Application Technology is the thing which developed in recent decades. With the ultrasonic advance, and the electronic technology development, especially as high-power semiconductor device technology matures, the application of ultrasonic has become increasingly widespread: � Ultrasonic measurement of distance, depth and thickness; � Ultrasonic testing; � Ultrasound imaging; � Ultrasonic machining, such as polishing, drilling; � Ultrasonic cleaning; � Ultrasonic welding;
