Ultrasonic transducer

A welding tool has an exister composed of multiple piezoelectric elements in a supporter, a sensor in the supporter, and another piezoelectric element between electrode and isolating crystal wafer. The voltage between electrodes is monitored for determining the welding parameters including the ample...

More Information
Summary:A welding tool has an exister composed of multiple piezoelectric elements in a supporter, a sensor in the supporter, and another piezoelectric element between electrode and isolating crystal wafer. The voltage between electrodes is monitored for determining the welding parameters including the ampletude and cycle of each ultrasonic wave.
