◈ What are the application scenarios of X-ray inspection?
X-ray inspection can be applied to a wide range of fields, including semiconductors, lithium battery inspection, injection molded parts, automotive parts, aviation parts, military industry, food, etc.
◈ What is non-destructive testing?
It is the detection of internal and surface defects of various engineering materials, parts and structural components by using changes in physical quantities such as heat, sound, light, electricity and magnetism caused by abnormalities or defects in the internal structure of materials
◈ What defects can be detected by X-ray inspection?
1. Light-emitting diode parts for cracks and foreign objects
2. To inspect and judge the defects such as broken wire and false welding in BGA welding
3.For detecting internal air control and crack defects in aluminum casting
4.Checking IC packaging for defects such as peeling, damage, gaps, etc.
5.SMT is mainly used to detect solder joint gap
6. In integrated circuits, mainly for detecting disconnection, short circuit or abnormal connection of various connection lines
7. In lithium battery, the defects such as poor alignment of stacked or wound rolls, too close spacing between negative pole and shell wall in the battery, and missing internal structure of pole lug
◈ What is the difference between X-ray inspection and AOI?
X-ray inspection is mainly for product internal inspection, while AOI is mainly for product surface inspection
◈ What is the difference between industrial CT and industrial DR?
Industrial DR is to display a flat image on the screen after X-rays pass through the object to be inspected, and to analyze the defects of the object to be inspected by observing the distribution of light and dark. In industrial CT, X-rays are captured by the detector after passing through the object to be inspected and transmitted to the computer, which will analyze and finally synthesize a three-dimensional image of the object, and then get the defects of the object to be inspected by observing the distribution of light and dark in the three-dimensional image
◈ What factors affect the final result of the radiographic inspection?
The results of radiographic inspection are influenced by the composition, density, thickness and power of the source
