X-ray tube assemblysource inspection technique, often called automaticX-ray tube assemblyInspection (AXI), is a technique for inspecting hidden features of objects or products using X-rays as a source. Conventionally, X-ray tube assembly inspection has been widely used in many fields such as medical, industrial control, and aerospace. About PCB inspection, X-ray tube assemblies are commonly used in the PCB assembly process to test the quality of the PCB. This is one of the important steps for quality-conscious PCB manufacturers.
X-ray tube component inspection is to use the transmission properties of various rays to materials and the absorption and attenuation levels of different materials to make the negatives photosensitive into images with different blackness to observe. It is an effective and indispensable method. It is widely used in industry to detect the internal defects of materials or parts.
Advantages of X-ray tube assembly inspection:
1. It is suitable for almost all materials, and there are no strict requirements on the geometric shape and surface roughness of the parts. At present, the ray inspection is mainly used for the inspection of castings and weldments;
2. The radiographic inspection can visually display the defect image, which is convenient for the qualitative, quantitative and positioning of the defect;
3. The ray film can be archived for a long time for future reference, which is convenient for analyzing the cause of the accident.
Defects detected by X-ray tube assemblies:
X-ray tube assemblyThe detection has higher flexibility for the detection of volume defects such as pores, slag inclusions, and looseness, but lower flexibility for the detection of plane defects. For example, it is difficult to detect when the ray direction is perpendicular to plane defects (such as cracks). In addition, the ray Harmful to the human body, maintenance measures are required.
