Abstract
The invention relates to a printed circuit board cleaning agent. The printed circuit board cleaning agent is prepared from the following raw materials in parts by weight: 30-40 parts of ethanol, 3-4 parts of disodium EDTA (Ethylene Diamine Tetraacetate), 1-2 parts of triethanolamine, 2-4 parts of citric acid, 20-25 parts of propylene glycol, 1-2 parts of sodium lauryl sulfate, 1-2 parts of 4-methyl salicylate, 1-2 parts of boric acid, 4-5 parts of adjuvants and 100-120 parts of deionized water. According to the cleaning agent disclosed by the invention, the preparation method is simple, no adverse effect on the environment is caused, the surface decontamination capacity is strong, the persistence of cleanliness can be maintained, the cleaning speed and durability are increased, and the cleaning effect on metallic ions is relatively strong, so that the subsequent use performance of circuit boards is improved; 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.
Description
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.
