| Abstract(in English) | A longitudinal wave velocity on piezoelectric ceramic substrate for ceramic filters and resonators is obtained from an electrical characteristics of filters and resonators after many manufacturing processes such as poling,electroding and so on.But this method has some problems that are long period for various processing and a serious processing dispersion.In order to dissolve the above- mentioned problems,we examined a measurement method for longitudinal wave velocity by pulse interference method using acoustic microscope.From the result of this experiment,we were able to obtain a fine correlation between the measurement value by acoustic microscope on piezoelectric ceramic substrate before process of poling and electroding,and the frequency characteristics of the filters or the resonatorsafter processing. |
