The invention relates to the field of circuit board cleaning, and provides an acid cleaning agent for circuit boards and a preparation method thereof, which are used to solve the problem of metal corrosion in the circuit board cleaning process. The invention provides an acidic cleaning agent for circuit boards and a preparation method thereof, comprising 2-8 parts by mass of sodium laureth sulfate, 1-10 parts by mass of coconut oil diethanolamide, 1-6 parts by mass of citric acid, 1-3 parts by mass of etchant, 6-8 parts by mass of dispersant NNO, 0.05-0.2 parts by mass of silicone oil defoamer, and 80-100 parts by mass of deionized water. The cleaning agent can effectively clean the surface of the circuit board without corroding the metal on the surface of the circuit board. |
