Description

technical field [0001] The invention relates to an X-ray detection system, in particular to an X-ray detection system for PCB board production. 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. However, in the existing X-ray detection technology, there is no special treatment for the imaging part. The simple X-ray emission tube directly irradiates the PCB board on the stage, and then f...

Problems solved by technology

However, in the existing X-ray detection technology, there is no special treatment for the imaging part. The simple X-ray emission tube directly irradiates the PCB board on the stage, and then forms an image on the image intensifier. The whole process is easily detected by the X-ray emission tube. The unstable factors of the light are interfered, and at the same time, the signal imaged on the image intensifier often produces unstable and blurred phenomena
