To accomplish a high-resolution ultrasonic imaging without wetting a sample, the efficiency
of the dry-contact ultrasonic transmission is discussed. In this study, a dry-contact interface is …

The measurement method, presented in the first part of the paper, is here used in several
application fields. A measurement procedure, aiming at a proper utilisation of the method …

Compared to the usual water immersion case, more effective transmission and reception of
high-frequency ultrasound through a thin, solid layer are reported. A theoretical model is …

The main goal of this paper is to describe a new method based on Continuous Wavelet
Transform (CWT) algorithm and successfully implemented in a Scanning Acoustic …

Scanning acoustic microscopy (SAM) is now a common detection method which produces
high resolution images with focused ultrasonic waves ranging from 10 to 500 MHz. In this …

This paper reports results on application of scanning acoustic microscopy (SAM) for analysis
of high-density microassembling technologies such as BGA and TSV. We have …

Resistance spot welding has been widely used in the industry to join steel sheets. The area
