Electronic assembling water-based detergent and cleaning method

Abstract

The invention provides an electronic assembling water-based detergent and a cleaning method. The electronic assembling water-based detergent is prepared from the following raw materials in percentageby mass: 6-12% of a surfactant, 0-0.1% of a corrosion inhibitor, 0-0.5% of a defoaming agent and the balance of deionized water, wherein the surfactant is prepared from a nonionic surfactant, a zwitterionic surfactant and a binary star nonionic surfactant through compounding; the nonionic surfactant accounts for 50-69% of the total weight of the surfactant; the zwitterionic surfactant accounts for20-49% of the total weight of the surfactant; and the binary star nonionic surfactant accounts for 1-30% of the total weight of the surfactant. Together with a cleaning process, the detergent is capable of strongly removing surface residues after welding of a rosin type welding flux, a welding point is kept bright, and good surface insulation is achieved; and the detergent is completely free of halogen, low in volatilization, safe and environmental-friendly, free of pollution substance, low in cost, simple in preparation method, free of bubble in the cleaning process, applicable to full-automatic cleaning and ultrasonic cleaning, and easy in cleaning process operation.

Description

technical field [0001] The invention belongs to the field of electronic industry cleaning agent manufacturing, and relates to a water-based cleaning agent for electronic assembly and a cleaning process method. Background technique [0002] With the development of the electronic industry, the requirements for the quality of electronic products are getting higher and higher. After welding, flux residues or other foreign contaminants not only affect the appearance of the product, but also deteriorate the reliability of the product, causing short circuits, corrosion and other electrical failures. [0003] The traditional cleaning agent containing ODS substances such as Freon has a good cleaning effect on grease rosin and other resins. However, such cleaning agents contain substances that destroy the ozone layer. Improper use of halogens and their compounds in the production process will cause harm to the health of workers and the environment. With the improvement of safety and ...

Problems solved by technology

The solvent of the cleaning agent contains organic alcohol ethers, among which diethylene glycol monomethyl ether, ethylene glycol monobutyl ether, and propylene glycol ethyl ether are flammable and cause fires, and during the preparation of the cleaning agent, especially ethylene glycol monomethyl ether Butyl ether can depress the central nervous system, high concentration may cause dizziness, nausea and other phenomena, extremely high concentration may cause loss of consciousness or even death

The other two ethers are also toxic and endanger human health
