New acoustic scanning method delivers greater throughput

Sonoscan Inc., a designer and manufacturer of acoustic microscope systems, introduced a new method of acoustic scanning that promises greater units-per-hour throughput for both automated and manual Sonoscan systems.

UPH-Turbo, the new acoustic scanning method, increases throughput when used with FACTS, the company's in-line automated acoustic inspection systems, which can handle thousands of parts per hour in trays. FACTS systems generally operate 24/7 and are dedicated to a specific application.

UPH-Turbo also increases throughput for Sonoscan's C-SAM systems, which are widely used in production environments where greater flexibility is needed and for laboratory analysis.

Sonoscan explained that acoustic microscopes work by pulsing VHF or UHF ultrasound from a scanning transducer into a part and receiving the return echoes from internal features at various depths within the part. The echoes come back only from material interfaces and not from homogeneous materials. "Until now, the constraints on the scan rate, and on overall throughput, have been the scanner mechanism design and the transducer itself," said Dr. Lawrence Kessler, president of Sonoscan.

The new scanning method is most useful when making higher resolution acoustic images. "It's really not needed at lower resolutions where throughput rates are usually high anyway. UPH-Turbo gives the greatest benefit at higher resolutions, where the throughput rate is up to 2.5 times what it would be without UPH-Turbo," added Kessler.
