Abstract

The invention relates to a printed circuit board cleaning agent prepared from the raw materials of, by weight: 4-5 parts of erucic acid, 3-4 parts of white oil, 3-4 parts of dodecylbetaine, 4-5 parts of fatty alcohol polyoxyethylene ether, 2-3 parts of sodium borate, 3-4 parts of coconut oleic oil alkylolamide phosphate, 2-3 parts of citric acid, 1-2 parts of fatty alcohol polyoxyethylene ether AEO-3, 30-40 parts of ethanol, 4-5 parts of an auxiliary agent, and 150-180 parts of deionized water. The cleaning agent provided by the invention has high-efficiency thorough cleaning function. According to the cleaning agent, a plurality of surfactants are applied in combination, and are well formulated. Therefore, cleaning effect is greatly improved, cleaning efficiency is improved, cleaning cost is saved, and economic benefit is increased. With the auxiliary agent, a protective film can be formed on the surface of the circuit board, such that oxidation and short-circuit can be prevented.

Description

Cleaning agent for printed circuit board and preparation method thereof

Technical field

The present invention relates to clean-out system field, relate in particular to a kind of cleaning agent for printed circuit board and preparation method thereof.

Background technology

Along with the high speed development of unicircuit, the volume of circuit card is more and more less, and electronic component is more and more less, and density is increasing.If the dirt dust of the inside does not clean up in making processes, likely can cause the problems such as short circuit, corrosion, affect the normal operation of circuit card.At present majority circuit plate sanitising agent is all made with organism, and cleaning effect is good, is difficult for causing the problems such as short circuit, corrosion, and still, organic compound not only cost is high, and contaminate environment, damage the ozone layer, harmful to HUMAN HEALTH.Also have minority waterborne cleaning agent, but cleaning performance is limited, has security risk, require further improvement formula, technique, to reach clean thorough, pollution-free, the object of corroding little, healthy, circuit safety, reducing costs.

Summary of the invention

The object of the present invention is to provide a kind of cleaning agent for printed circuit board and preparation method thereof, this clean-out system have advantages of clean thoroughly, cleaning speed is fast.
