[ China Instrument Network Instrument Development ] Recently, China Electronics Branch 38 released a new generation of non-destructive testing equipment independently developed by the “Super Needle†X-ray imaging system, which is the country's first “Super Needle†X-ray imaging system. The system has a "eye-catching" defect detection capability with an imaging resolution of less than 1 micron.
With the development of integrated circuits in the direction of high integration and miniaturization, advanced packaging processes pose new demands and challenges for package inspection equipment. On the one hand, finer package sizes require device resolutions to be sub-micron, but there are only a handful of manufacturers that can produce sub-micron resolution devices internationally; on the other hand, as chip manufacturing and packaging processes become more and more The use of light-element materials such as silicon, aluminum, copper, and ceramics has become increasingly demanding for the detection of light-element materials, and higher requirements have been placed on the detection range of equipment. Therefore, X-ray inspection equipment with higher resolution, higher contrast, and larger detection range has become an urgent need for the development of the integrated circuit package inspection industry.
Micro-focus X-ray imaging system is a routine equipment for industrial non-destructive testing. It is widely used in non-destructive testing of various devices such as integrated circuits and electronic devices. It can observe the fine structure inside the object, and the performance of the X-ray source directly determines The detection capabilities of such devices. Super needle is a theoretically optimal source of electrons.
In 2011, China Electronics 38 first proposed the application of super-needle to the development of micro-focus X-ray sources. After nearly a decade of technical research, the Super Needle X-ray Imaging System finally came out. At present, 38 of China Electronics has applied for more than 30 domestic and foreign invention patents for this product, including 12 international patents including US, Japan and Europe.
The "Super Needle" X-ray imaging system uses a unique patented "Super Needle" X-ray source to create a fluoroscopic image of the scanned object on the image intensifier. The device adopts the “super needle†X-ray source pioneered by the country, and thus has the title of “Super Needleâ€, which has the advantages of clear imaging, stable performance, high cleanliness, ultra-low radiation and low energy imaging.
According to the relevant person in charge of 38 of China Electronics, based on super-needle X-ray source technology, it can develop a series of super-needle X-ray imaging equipment for different application fields such as integrated circuit, military aerospace, automotive electronics, medical diagnosis, etc. Diversified development, the future has great development prospects.
