New architecture could be used to create tailored devices that emit or receive only certain frequencies of sound ...

Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods ...

As 3D packages become increasingly complex, so do the challenges in identifying defects within vertically stacked, multiple layers. Focus is now shifting to methods of non-destructive testing such as ...

SAM equipment detects cracks, voids, and other flaws as small as 5 microns in vertically stacked, hybrid bonded packages.

New acoustic microscopy techniques, such as scanning acoustic microscopy (SAM) and time-of-flight acoustic microscopy (TOF-AM), enable the detection and characterization of very small defects, such as ...

Based on the above insights, a research team from the University of Hong Kong recently reported near-infrared photoacoustic remote sensing microscopy for noncontact imaging of lipids.

New developments in scanning acoustic microscopy, also known as ultrasonic non-destructive testing, position the quality inspection technology for use by manufacturers of all sizes. Most automated ...

Nanoacoustic Characterization Scanning acoustic microscopy (SAM): Sound waves with high frequencies have short wavelengths and are used to develop acoustic microscopes. These microscopes have a ...
