Abstract
The invention relates to a water-based LED (Light-Emitting Diode) chip cleaning agent. The water-based LED chip cleaning agent is prepared from the following raw materials in parts by weight: 3-4 parts of heterogeneous fatty alcohol polyoxyethylene ether, 1-2 parts of monostearate glyceride, 2-3 parts of sodium salicylate, 20-25 parts of propanediol, 10-12 parts of 1, 3-dioxolane, 3-4 parts of rosin, 30-35 parts of ethyl alcohol, 6-8 parts of tert-butyl-4-hydroxy anisole, 4-5 parts of tripropylene glycol methyl ether, 4-5 parts of additive and 100-120 parts of deionized water. By adopting the water-based LED chip cleaning agent, as a nonionic surfactant is used, the water-based LED chip cleaning agent is good in the synergistic effect and has rapid cleaning ability to organic matters, metal ions, particles and the like, new ionic soil can not be generated, and a chip is not corroded; as the loss is less, the cost is lowered, and the time is saved, the chip yield is greatly increased; as the additive can be used for forming a protective film on the surface of the chip, air is isolated, water and other molecules in the atmosphere are prevented from corroding the chip, and the additive can be used for resisting oxidation and is convenient for a next manufacturing process.
Description
Technical field
The present invention relates to clean-out system field, relate in particular to a kind of water base LED chip clean-out system and preparation method thereof.
Background technology
The industry Wafer Cleanings such as silicon slice detergent is widely used in photovoltaic, electronics; Because silicon chip can pollute to some extent in transportation, surface cleanliness is not very high, the corrosion and the etching that are about to carry out is had a huge impact, so first will carry out a series of cleaning operation to silicon chip surface.First the general thinking of cleaning is to remove surperficial organic contaminations, and dissolved oxygen film then, because zone of oxidation is " contamination fall into into ", can cause epitaxy defect; Remove again particle, metal etc., make the surface passivation of silicon chip simultaneously.
Current most silicon slice detergent adopts a liquid and No. three liquid in RAC cleaning, but the aobvious alkalescence of liquid may cause silicon face coarse, strictly control temperature, concentration and time; No. three liquid is aobvious acid, has severe corrosive, also unfavorable to HUMAN HEALTH, production cost is high, irritant smell, contaminate environment, therefore require further improvement formula, with reach clean thorough, pollution-free, corrode little, to HUMAN HEALTH, circuit safety, the object that reduces costs.
Summary of the invention
The object of the present invention is to provide a kind of water base LED chip clean-out system and preparation method thereof, this clean-out system has clean thorough, high, the non-corrosive advantage of cleaning efficiency.
Technical scheme of the present invention is as follows:
A kind of water base LED chip clean-out system, it is characterized in that being made by the raw material of following weight part: isomery fatty alcohol-polyoxyethylene ether 3-4, single stearic acid glycerine lipoprotein 1-2, sodium salicylate 2-3, propylene glycol 20-25, DOX 10-12, rosin 3-4, ethanol 30-35, tertiary butyl-4-hydroxy methyl-phenoxide 6-8, tripropylene glycol methyl ether 4-5, auxiliary agent 4-5, deionized water 100-120;
