Failure Analysis - Non-Destructive Evaluation - Scanning Acoustic Microscopy (SAM)
Non-Destructive Evaluation - Scanning Acoustic Microscopy (SAM) - Introduction Scanning acoustic microscopy (SAM) uses acoustic impedance to produce high resolution images of a sample s interior structure to detect difficult-to-find defects, such as interfacial separation (PEMs and PWBs), solderball delamination (BGAs), and die attach voiding (PEMs). Both delamination/cracking and die attach ...

Ultrasonic Terms
Ultrasonic Terms Absolute error - The difference between a measurement and ites true value. We must estimate the true value so this is often expressed with confidence intervals. Acoustic Ohm - Unit of acoustic resistance. An acoustic impedance is one ohm (cgs) when a sound pressure of 1 microbar produces a volume velocity of 1 cubic cm per second. Used mostly in resonator applications and not ...
