Acoustic microimaging is a critical part of moisture sensitivity testing for plastic encapsulated microcircuits.  The pair of images above shows the increase in heat sink delamination (red) on a plastic IC, before and after moisture sensitivity testing per J-STD-020A.   This would not represent a failure per that standard.  More below...

The images above are pre- and post-test through-transmission images of a ceramic BGA with an overmolded chip.  The black in the right image near the die perimeter indicates delamination.   Interface scans proved the delamination was within the substrate (probably under the chip pad).  This does represent a failure per J-STD-020A.  (Note that through-transmission scans are accepted methods for evaluating BGAs.)

AcousTech Inc. is a testing laboratory providing C-SAM acoustic microimaging or acoustic imaging, x-ray,
and other failure analysis related services. C-SAM or SAM acoustic microimaging or acoustic imaging, or scanning
acoustic microscopy, is a useful failure analysis tool involving nondestructive testing. Acoustic microimaging
or acoustic imaging or scanning acoustic microscopy is sometimes called Sonoscan testing, because Sonoscan
is a well-known equipment manufacturer of C-SAM acoustic imaging equipment. Sonoscan and Sonix both make
acoustic microimaging or acoustic imaging nondestructive testing equipment. Sonoscan and Sonix use other
names for acoustic microimaging or acoustic imaging, like C-SAM, SAM, Dr. SAM, TAMI, and FACTS. Names like
Dr. SAM, TAMI, and FACTS are registered trademarks of their respective companies. Failure analysis scanning
professionals depend on C-SAM or CSAM acoustic micro acoustic imaging much as they do x-ray or radiographic
analysis. AcousTech Inc. provides C-SAM acoustic microimaging or acoustic imaging as a service. We do not
sell equipment like Sonoscan or Sonix.

Applications for C-SAM acoustic micro imaging include cracked plastic ICs, or PEMs, and also MEMS applications such as silicon/silicon bonded wafers, and glass/silicon bonded wafers. This technique offers much better resolution than traditional IR testing scanning.
