Problems solved by technology

The cleaning agents used in current chemical cleaning include organic solvent cleaning agents, semi-aqueous cleaning agents and water-based cleaning agents. , trichlorethylene, freon, etc., such cleaning agents have serious air pollution. Although the existing water-based or semi-aqueous electronic cleaning agents have avoided pollution to the atmospheric environment, in terms of their use effects, they are not as good as electronic cleaning agents. The lack of functionality in the cleaning of components, that is, it is difficult to ensure the integrity of electronic components
Optical cleaning, although the cleanliness of the cleaning is high, the required equipment is expensive, most of which are imported, the investment is too large, and it may affect the photoelectric characteristics of electronic components
Electric pulse cleaning, the equipment required for cleaning is complex and expensive, and due to the existence of hydroelectric effect, it may affect the electrical and magnetic properties of electronic components
