Problems solved by technology

[0002] The surface of finished electronic devices and their semi-finished products needs to be cleaned before subsequent processing. With the rapid development of science and technology, there are more and more fields of application of electronic devices, which makes the use of electronic devices continue to increase. In order to meet the follow-up processing The requirements for preparation require a large amount of cleaning of electronic devices and their semi-finished products, and the amount of cleaning agent required in the cleaning process must also be quite large. In addition, most of the existing cleaning agents for oil stains on electronic devices are solvent-based cleaning agents. The disadvantage of the agent is that the cleaning effect is not very ideal, and the cleaning time is long, usually 10 to 30 minutes; the surface of the electronic device after cleaning is prone to black surface layer, which brings troubles to subsequent processing, especially for precision The processing of electronic devices used in instruments and equipment causes confusion; and this type of cleaning agent is corrosive to the equipment, increasing the cost of the equipment
