Image intensifier for X rays

Abstract

The invention discloses an image intensifier for X rays. The image intensifier comprises a sealed casing, wherein an intensifier module, a CCD module and an electricity supply module are arranged in the sealed casing; an input screen and an output screen are arranged on the intensifier module, and an input window corresponding to the input screen is formed in the sealed casing; the CCD module comprises a CCD camera and a diaphragm arranged in front of a lens of the CCD camera and used for filtering and removing impurity light rays, wherein the CCD camera is arranged at the position of the output screen; the electricity supply module comprises a transformer, a rectifier, a high-pressure package and a voltage doubling component, and the intensifier module and the CCD module are respectively connected with the electricity supply module. The image intensifier disclosed by the invention is simple in structure, reasonable in design and convenient to mount, the intensifier module and the CCD module are encapsulated in one casing, the image intensifier is good in sealing property, the signal attenuation is avoided, and the image intensifier is steadier and more reliable in operating properties, so that an accurate and effective detection result is ensured, besides the image intensifier is simple and convenient to operate and good in use effect and has a high popularization value.

Description

technical field [0001] The invention belongs to the technical field of X-ray images, in particular to an X-ray image intensifier. Background technique [0002] With the rapid development of electronic science and technology, the miniaturization of packaging, the high density of assembly, and the continuous emergence of various new packaging technologies, strict requirements have been put forward for the quality inspection of surface mount technology (SMT) assembly products. Traditional manual visual inspection, automatic optical inspection (AOI), laser inspection, in-circuit testing (ICT) and other inspection technologies can no longer meet the requirements. [0003] The use of automatic X-ray inspection technology (AXI) has become the main method to solve the problem. It can not only detect hidden solder joints, such as BGA (Ball Grid Array Package), but also perform qualitative and quantitative analysis on the detection results, find electronic assembly failures in time, ...

AI Technical Summary

Problems solved by technology

[0005] The image intensifier in the X-ray detection system is an essential component. After the X-ray passes through the PCB board, the image intensifier is used to receive and intensify the image, and finally the image information on the image intensifier is extracted by the CCD camera and handed over to the computer for processing; The traditional image intensifier and CCD camera are set separately, and separate setting is easy to cause signal attenuation, so that the image information captured by the CCD camera is different from the actual inspection image, which affects the inspection quality
