SBT Commences Volume Shipments of Ultrasonic Inspection Equipment for AI Data Center Cold Plate Safety
Shanghai, China – SBT ULTRASONIC (Stock Code: 688392) has launched volume shipments of its self-developed CP-US1008 Scanning Acoustic Microscope (C-SAM), designed for liquid cold plates in AI servers. This milestone marks a major breakthrough in high-end nonDestructive Testing (NDT) equipment for AI chips, offering SBT’s solution to ensure liquid cooling safety in the era of AI computing.
As global AI and cloud computing see explosive growth, traditional air cooling can no longer meet the thermal management needs of high-power data centers. High-performance computing equipment is driving surging demand for efficient liquid cold plates—along with rigorous inspection of their structural integrity and reliability. Under extreme high-pressure, high-density operating conditions, micro-scale defects in cold plates (such as cold solder joints or leak points) can compromise entire thermal management systems.
Scanning Acoustic Microscopy (SAM) is the industry’s preferred NDT method for cold plate inspection, outperforming alternatives in resolution, speed, and 3D reconstruction capabilities. Using a water-immersion coupling technique, SAM transmits Ultrasonic waves into materials and analyzes variations in signal amplitude to pinpoint internal defects—including weld cracks, inclusions, voids, and incomplete fusion—with micron-level precision.
SBT’s CP-US1008, developed specifically for AI server cold plates, features an industry-leading 1–75 MHz wide-frequency probe, upgrading defect detection precision from the millimeter to the micron scale. Its multi-probe simultaneous scanning (with 2/4/6/8 probes optional) significantly boosts throughput and production flexibility.
Core Innovations:
✅ Flexible platform: Adapts to diverse product dimensions
✅AI-powered defect recognition: No secondary development required
✅ Smart factory integration: Includes permission management and maintenance alerts
✅ High precision and efficiency: Boosts production yield
✅ One-click measurement: Easy operation
This shipment milestone underscores SBT’s commitment to independent R&D and advancing ultrasonic technology. Leveraging its robust ultrasonic platform and collaborations with institutions like Shanghai Jiao Tong University, SBT has overcome critical challenges in high-frequency ultrasonic imaging, precision motion control, and AI-driven complex structure recognition. The company now develops and supplies core components in-house—including high-frequency pulsers, precision transducers, and high-speed data acquisition cards—bolstering its position in high-end smart manufacturing equipment.
SBT offers a comprehensive SAM product portfolio for cold plates, including high-precision single-, multi-channel, and phased-array systems. These solutions accurately identify micron-scale voids, cracks, and delamination in cold plates and heat sinks. Integrated with AI defect recognition, they deliver superior accuracy and efficiency, facilitating domestic substitution of high-end cold plate inspection equipment.
