Abstract
The invention provides a water-based acid printed circuit board cleaning agent. The cleaning agent is prepared from the following raw materials in parts by weight: 30-34 parts of ethanol, 3-4 parts of hydrofluoric acid, 4-5 parts of polyoxyethylene lauryl ether, 30-35 parts of n-butyl alcohol, 1-2 parts of ethanolamine, 2-3 parts of citric acid, 1-2 parts of sodium citrate, 2-3 parts of potassium peroxomonosulfate, 1-2 parts of benzalkonium chloride, 4-5 parts of auxiliary and 100-120 parts of deionized water. The cleaning agent has the beneficial effects that the cleaning agent is weakly acidic, has good surfactant compound property, good buffering effect, high cleaning speed and low corrosivity, and improves the cleaning efficiency; the auxiliary can form a protective film on the surface of the circuit board to isolate air to prevent water and other molecules in the air from corroding the circuit board; the cleaning agent is resistant to oxidation, prevents short circuit and is convenient for operation of the next preparation process.
