Abstract
The invention relates to a weak-acidity printed circuit board cleaning agent. The weak-acidity printed circuit board cleaning agent is prepared from the following raw materials in parts by weight: 2-3 parts of hydrofluoric acid, 4-5 parts of erucic acid, 3-4 parts of white oil, 5-6 parts of stearic acid, 3-4 parts of dodecyl betaine, 2-3 parts of trisodium phosphate, 4-5 parts of fatty alcohol-polyoxyethylene ether, 2-3 parts of sodium benzoate, 4-5 parts of adjuvants and 100-120 parts of deionized water. According to the cleaning agent disclosed by the invention, due to the use of hydrofluoric acid, the cleaning agent has an efficient and thorough cleaning effect, and due to the matched use of a variety of surfactants, the compatibility is good, the cleaning effect is greatly enhanced, the cleaning efficiency is accelerated, the cleaning cost is reduced, and the economic benefit is increased; the adjuvants of the cleaning agent can form a protective film on the surface of a circuit board, so as to isolate air to prevent water and other molecules in the atmosphere from corroding the circuit board to resist oxidation and prevent short circuit, and the implementation of a next production process is facilitated.
