Abstract

Cold-welding indium layers deposited on metal films constitutes a bonding method for the transducers of ultrasonic delay lines suitable for operation at bit rates beyond 100 MHz. This method permits the use of transducer materials with high coupling factor, resulting in delay lines with comparatively low insertion loss.
