Abstract
The invention provides a fingerprint cleaning fluid. The fingerprint cleaning fluid is mainly prepared by mixing the following components in mass ratio: 70-85 parts of anhydrous ethanol, 5-10 parts of isopropanol and 10-25 parts of deionized water. The fingerprint cleaning fluid is prepared by compounding alcohol compounds and is free of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl, polybrominated diphenyl ether and the like; fingerprint contaminants on an electronic circuit board can be quickly and effectively removed, the cleaning fluid is easily volatile and has no corrosion to the circuit board, and no residue is caused.
Description
Technical field
The present invention relates to a kind of fingerprint scavenging solution.
Background technology
Mobile phone screen wiring board, precision element etc. in the fabrication process, often can leave fingerprint accidentally on element.Fingerprint is the stain that the organic dirt pointed of operator and mineral contaminants are trapped on element, adopt existing solvent cleaning, the organic pollutant falling to be detained capable of washing, and the inorganic pollutant being difficult to wash in the fingerprints such as the sodium-chlor with corrosive nature, in use afterwards, the risk of lie dormant circuit and the oxidized corrosion of element.
Summary of the invention
The present invention proposes a kind of fingerprint scavenging solution, adopt alcohols etc. compound is composite and form, not leaded, mercury, cadmium, sexavalent chrome, Polybrominated biphenyl and Poly Brominated Diphenyl Ethers etc., fast and effeciently can remove the fingerprint pollution thing on electronic circuit board, comprise organic and inorganic pollutant, and volatile, noresidue, to wiring board without potential oxidation corrosion risk.
Technical scheme of the present invention is achieved in that
A kind of fingerprint scavenging solution, be mixed to form primarily of dehydrated alcohol, Virahol and deionized water, its quality proportioning is: dehydrated alcohol: 70 ~ 85 parts, Virahol: 5 ~ 10 parts, deionized water: 10 ~ 25 parts.
Preferably, the quality proportioning of scavenging solution is: dehydrated alcohol: 80 parts, Virahol: 8 parts, deionized water: 12 parts.
Further, the density of scavenging solution is 0.800-0.820 g/cm
3.
Beneficial effect of the present invention is: in the present invention, the proportioning of water is too many, exceeds preferred proportion and volatilization can be caused comparatively slow, affect productive temp; Be less than preferred proportion and effectively can cannot remove the mineral contaminants compositions such as the sodium-chlor in fingerprint spot; Alcohols is less than preferred proportion in addition, effectively cannot remove the oily matter in fingerprint spot.
Adopt Virahol and alcohol mixture in formula, the synergy of both performances, enhances effect of deoiling.
The fingerprint pollution thing on electronic circuit board fast and effeciently can be removed by the fingerprint scavenging solution of program proportioning, volatile, noresidue, corrosion-free to wiring board, and also toxicological harmless, safe and reliable, there is good practical value.
