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 ...
