Internal defects such as delaminations, cracks and voids within ceramic chip capacitors can lead to product failure.

Sonoscan Lab Aids In Investigation For Dan Rather Reports

Elk Grove Village, IL — November 12, 2007

Sonoscan’s Silicon Valley applications laboratory (SSV) in Santa Clara, CA was selected recently to appear in an episode of HDNet’s “Dan Rather Reports” dealing with the testing of composite materials.  The episode, which premiered on September 18, is entitled “Plastic Planes” and is available for viewing or download at

The SSV lab was used to demonstrate how acoustic micro imaging can evaluate multi-layer composite materials for internal damage. One of the problems that the aircraft industry faces is that a composite material that has experienced impact may show no surface damage but may have significant internal damage.

Because of their unique structure, these composite materials are difficult to evaluate for internal damage by other methods.  But a C-SAM® acoustic microscope system will show structural damage layer by layer, even in cases where the top layers have no damage but deeper layers are cracked.

“We are happy that HDNet chose us to take part in this episode,” said SSV manager Lisa Logan.  “Sonoscan has a long history of imaging composite materials, and did some of the earliest work with the multilayer polymer composites that the aircraft industry is interested in.”
