The ECHO scanning acoustic microscope is a nondestructive ultrasonic flaw detector designed to simplify testing, increase yield and maximize productivity in the lab or on the production floor.

This industry-leading scanning acoustic microscope provides a universal inspection tool for packaged semiconductor development, production and failure analysis. With the ability to detect air defects as thin 0.05 micron and spatially resolve defects down to 10 microns, the ECHO is perfect for bump detection, stacked die (3D packaging) inspection, complex flip chip inspection and more traditional plastic packages.
