Description

Technical Field

[0001] The present invention relates to the technical field of detectors, and in particular to a highly shielded X-Ray detection device and a process method thereof. Background Art

[0002] X-rays are particle streams generated by the transition of electrons in atoms between two energy levels with a large difference in energy. They have a very short wavelength of about 0.01-100 angstroms, and are electromagnetic radiation between violet and gamma rays. X-rays are widely used in production, life and scientific research activities such as medical testing and industrial non-destructive testing. In the process of electronic manufacturing, X-ray detection technology is widely used, which can be used for semiconductor front-end processing detection, chip packaging detection, circuit board line detection, electronic device welding detection, battery detection, etc. At the same time, the application of welding quality detection after reflow soldering in SMT is also becoming more and more widespread. The welding quality detection of hidden solder joints of electronic components cannot be achieved by visible light, so non-destructive testing by X-ray penetration is required.

[0003] At present, the X-ray generation technology used in SMT production lines is the micro-focus X-ray source solution. The micro-focus X-ray sources on the market all adopt the single-tube single-emitter solution. In 3D detection applications, the X-ray source with a single tube and a single emitter corresponds to a single X-ray receiving plate. Multiple displacements and multiple image acquisitions are required between the X-ray source and the receiving plate, which is slow, inefficient, and difficult to control the position accuracy of the movement; there is also the position offset of the detection object, and there is no correction function, etc. The stage will also interfere with the X-rays, etc.

[0004] Therefore, in view of the above problems, the existing detector technology needs to be further improved. Summary of the invention
