Sonoscan Launches HiRes Generation THRU-Scan™

Elk Grove Village, IL — July 1, 2008

Sonoscan, Inc., has introduced the HiRes Generation THRU-Scan™, which significantly enhances through-transmission imaging with Sonoscan’s C-SAM® line of acoustic microscopes.

Reflection-mode acoustic imaging (the most frequently used mode) is limited to a defined depth within a sample, but THRU-Scan images the whole thickness in one scan.  For example, a plastic-encapsulated microcircuit might have 5 layers.  Reflection-mode imaging typically selects one or two internal interfaces to image for anomalies or defects.

But THRU-Scan images the whole thickness of the part – all 5 layers and all 4 interfaces – simultaneously, and reveals a defect or anomaly at any depth.  By itself, THRU-Scan provides a fast non-destructive method for determining whether an internal defect is present. Often THRU-Scan is used along with reflection-mode imaging to simultaneously verify the x-y location of a defect and specify its depth.

HiRes Generation THRU-Scan differs from previous versions by permitting much higher resolution in the acoustic image without sacrificing penetration.  Edges are more sharply defined, contrast is greater, and thicker samples can be imaged.

For more information, contact Steve Martell, manager of technical support services.
