Description

technical field [0001] The invention relates to a high-voltage power supply, in particular to a high-voltage power supply for a micro-focus X-ray tube detected by surface mount technology (SMT). Background technique [0002] SMT (Surface Mount Technology) is currently the most popular and widely used technology in the electronic assembly industry. The use of SMT technology can reduce the volume of electronic products by 40-60% and reduce the weight by 60-80%. But what followed was that traditional detection methods, such as ordinary focus X-ray machines, could no longer meet the quality and reliability requirements of existing production products, especially for internal defects of components. In this environment, the micro-focus X-ray machine came into being, which has the incomparable advantages of traditional detection methods such as penetrating detection, wide detection range, and high cost performance. However, if the X-ray tube of the micro-focus X-ray machine needs t...

But what followed was that the traditional detection methods, such as ordinary focus X-ray machines, could no longer meet the quality and reliability requirements of existing production products, especially for internal defects of components that could not be identified.

In this environment, the micro-focus X-ray machine came into being, which has the incomparable advantages of traditional detection methods such as penetrating detection, wide detection range, and high cost performance. However, if the X-ray tube of the micro-focus X-ray machine needs to work , there must be a micro-focus X-ray tube high-voltage power supply as a power source. At present, the cost of the existing micro-focus X-ray tube high-voltage power supply is relatively high and the compatibility is poor.
