Through the use of ultra-high frequency ultrasound, typically above 10 MHz, Acoustic Microscopy (AM) non-destructively finds and characterizes physical features and latent defects (visualization of interior features in a layer by layer process) - such as material continuity and discontinuities, sub-surface flaws, cracks, voids, delaminations and porosity. AM observed features and defects can be indicators that the components were improperly handled, stored, altered or previously used.
