1. Overview of X-Ray Nondestructive Testing Technology
X-ray NDT is a nondestructive testing technology based on the penetrating properties of X-rays. It uses the attenuation differences of X-rays as they penetrate an object to generate images of the internal structure, thereby identifying defects, cracks, pores, and other problems within the material. Its core principle is to use an X-ray tube to generate high-energy rays. After penetrating the object being inspected, a detector captures the intensity distribution of the rays and converts them into a visual image using digital imaging technology.
For example, Seamark industrial CT/3D X-ray inspection equipment is equipped with innovative self-developed intelligent inspection software and professional CT analysis and visualization software. It has planar CT and cone beam CT functions, 360° arbitrary viewing angle inspection, and algorithmic reconstruction of three-dimensional models, which can achieve sub-micron precision defect detection.
Compared to traditional inspection methods, X-ray nondestructive testing offers the following advantages:
Non-contact inspection: Avoids physical damage to high-value workpieces and is suitable for precision electronic components, aerospace parts, and more.
Full-dimensional imaging: 2D/3D imaging technology clearly displays internal structures, eliminating blind spots in traditional inspections.
Intelligent analysis: Incorporating AI algorithms, it automatically identifies defect types, significantly improving inspection efficiency and accuracy.
2. Core Application Scenarios of X-Ray NDT Equipment
X-Ray technology has been widely used in all aspects of industrial manufacturing. The following are typical application areas:
2.1 Electronics manufacturing and semiconductor packaging
Chip and PCB Inspection: In SMT, X-ray can penetrate multi-layer circuit boards to inspect microscopic defects such as BGA solder joint defects, IC through-silicon via (TSV) fractures, and residual copper in PCB drill holes.
Semiconductor Package Verification: 3D X-ray and industrial CT can provide a three-dimensional view of packaged chips, analyzing parameters such as solder ball voiding to help improve package yield.

2.2 Automobile manufacturing and new energy sectors
Power lithium battery inspection: For cylindrical and prismatic batteries, X-ray can inspect issues such as tab misalignment, welding defects, and abnormal winding layers. For example, Seamark XB7100 wound battery X-ray inspection equipment supports high-speed inline inspection at 60 parts per minute (PPM), with an accuracy of 5-15μm and a false positive rate of less than 0.5%.
Automotive parts flaw detection: Internal cracks, shrinkage, and other defects in key components such as engine blocks and new energy battery trays can be identified through real-time X-Ray imaging to ensure driving safety.
2.3 Precision manufacturing and casting inspection
Aerospace components: X-ray CT scanning can be used to fully inspect internal defects in complex workpieces such as titanium alloy structures and carbon fiber composites, ensuring high quality.
Die-casting quality control: During the casting process, X-rays can quickly detect problems such as pores and pinholes, effectively reducing product scrap due to defects and lowering production costs.
