In the field of smart manufacturing and high-end equipment, industrial non-destructive testing is a core technology for ensuring product quality and enhancing process safety. Traditional testing methods (such as X-ray and eddy current testing) are limited by resolution, penetration depth, or material compatibility, making it difficult to address the demands of nanoscale defect analysis and complex structure detection. High-precision ultrasonic scanning acoustic microscopes (SAM), with their nanometer-level resolution, non-contact imaging, and multi-modal data fusion capabilities, are becoming a disruptive technology in the industrial inspection field.
Ultrasonic scanning acoustic microscopes operate by using a pulse generator to emit signals. These signals are then converted into mechanical vibrations by an ultrasonic transducer. Using phased array technology, the phase of the sound waves is dynamically controlled to form a nanometer-scale focal point that penetrates the interior of the sample. As the ultrasonic waves propagate through the material, they encounter defects (such as cracks or inclusions), which generate reflected and scattered signals. The transducer converts these signals back into electrical signals, which are then collected via an Analog-to-Digital Sampling (ADS) system for imaging.
Composite Materials: Ultrasonic scanning acoustic microscopes can identify delamination, fiber breakage, and internal voids in carbon fiber-reinforced polymers (CFRP).
Semiconductor Industry: Ultrasonic scanning acoustic microscopes can be used to detect surface cracks on wafers, photoresist residues, and defects in metal lines, aiding in process optimization for wafer manufacturing.
Metalworking: Ultrasonic scanning acoustic microscopes can be applied to detect internal inclusions, pores, and weld seam cracks in various metal materials, improving the yield of components in industries such as automotive and shipbuilding.
Batteries: Ultrasonic scanning acoustic microscopes can monitor the thermal shrinkage of battery separators in real-time, preventing short circuits in batteries.
