Acoustic microscopy and impedance analysis have emerged as pivotal tools in the non‐invasive investigation of biological tissues. By utilising high-frequency sound waves, these techniques deliver ...

A large lot of plastic-packaged ICs is on its way to surface-mounting. The components have passed electrical inspection, where those having functional defects were removed. They have passed optical ...

Figure 1. Ultrasound pulsed into a part by the scanning transducer is partly reflected by a well-bonded interface (at left); the remaining portion of the ultrasound travels deeper into the part. A gap ...

A single pulse of ultrasound fired into the polymer encapsulant of a TO-247 device travels through the polymer at a speed around 3,000 m/s. Its mission is to characterize any internal material ...

Accurate, continuous blood pressure (BP) monitoring is essential for preventing cardiovascular events, yet conventional cuffs ...

This study reviews recent advances in ultrasonic cement bond quality evaluation and proposes a unified framework for enhanced signal processing in ...
