Abstract
The invention relates to a weak-alkaline water-based circuit board cleaning agent prepared from the raw materials of, by weight: 2-3 parts of sodium phosphate, 4-6 parts of alkyl phenol polyoxyethylene ether, 5-9 parts of caprylin, 4-6 parts of propylene glycol monomethyl ether acetate, 1-2 parts of Span-80, 4-5 parts of nonylphenol polyoxyethylene ether, 30-40 parts of ethanol, 3-4 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, 4-5 parts of an auxiliary agent, and 100-120 parts of deionized water. The cleaning agent provided by the invention is weakly alkaline, and has low surface tension. The agent is suitable for circuit board and part cleaning. With the cleaning agent, welding flux, rosin, organics, dust, and the like can be effectively removed, and static electricity can be eliminated. The cleaning agent has low corrosion, and is safe and reliable to use. The treatment and discharge of waste cleaning agent are convenient, and ozone layer is not damaged. With the auxiliary agent provided by the invention, a protective film is formed on the surface of the circuit board, such that air is isolated, and the circuit board is prevented from being corroded by water and other molecules in the atmosphere. Therefore, oxidation and short-circuit can be prevented, and a next step of manufacturing process can be conveniently carried out.
