Definitions
- the present invention relates to a cleaning composition and more particularly to a cleaning composition which is suitable for removal of fluxes, fats and oils, dust, etc. deposited on IC components, components of precision instruments or the like.
- R-113 is nonflammable, low in toxicity and excellent in stability. Further, R-113, which has a proper solvency, can selectively dissolve only dirts and is unlikely to corrode metals, plastics, elastomers and the like.
- Printed boards to be cleaned for removal of fluxes are mostly composite products composed of metals, plastics, elastomers and the like. Also from this viewpoint, R-113 is beneficial.
- R-113 is being restricted because R-113 would be likely to destroy the ozone layer in the stratosphere and may become the cause of cutaneous cancer.
- a cleaning composition containing as an active component an aliphatic fluorohydrocarbon represented by the formula C n F m H 2n +2-m wherein 4 ⁇ n ⁇ 6 and 6 ⁇ m ⁇ 12.
- the cleaning composition according to the invention contains as an active component an aliphatic fluorohydrocarbon represented by the formula C n F m H2n+2-m wherein 4 ⁇ n ⁇ 6 and 6 ⁇ m ⁇ 12.
- Such compound has never been used as a cleaning agent for removing fluxes, fats and oils, etc.
- Examples of aliphatic fluorohydrocarbons present in the cleaning composition of the invention are compounds represented by the formulas C4F6H4, C4F8H2, C5F7H5, C5F8H4, C5F9H3, C5F10H2, C6F9H5 and C6F12H2, respectively.
- aliphatic fluorohydrocarbons are 1, 1,2,3,4,4- hexafluorobutane (HCF2CFHCFHCF2H), 1,1,1,2,2,3,3,4- octafluorobutane (CF3CF2CF2CH2F), 1,1,2,2,3,3,4- heptafluoropentane (HCF2(CF2)2CFHCH3, 1,1,2,3,3,4,5,5- octafluoropentane (HCF2CFHCf2CFHCF2H), 1,1,2,2,3,3,4,4,5,- nonafluoropentane (HCF2(CF2)3CH2F), 1,1,1,2,3,3,4,4,5,5,- decafluoropentane (CF3CF(CHF2)CF2CF2H), 1,1,1,2,2,3,3,4,4,- nonafluorohexane (CF3(CF2)3CH2CH3), 1,1,2,2,3,3,4,4,5,5,6,6- dodecafluorohexane
- the above-exemplified alipahtic fluorohydrocarbons can be used singly or at least two of them are usable in mixture.
- the amount of the aliphatic fluorohydrocarbon to be contained in the cleaning composition of the invention is not specifically limited, usually about 7O% by weight or more, preferably about 8O% by weight or more.
- the composition of the invention may contain at least one organic solvent selected from the group consisting of hydrocarbons, alcohols, esters and ketones in order to increase the solvency for dissolving fluxes.
- the amount of the organic solvent used is not specifically limited, usually about 30% by weight or less, preferably about 0.5 to about 10% by weight, more preferably about 1 to about 8% by weight, based on the whole amount of the cleaning composition of the invention. If the mixture of the aliphatic fluorohydrocarbon and the organic solvent can be an azeotropic composition, it is preferred to use the mixture as the azeotropic composition.
- Useful hydrocarbons are not specifically limited. Preferred hydrocarbons are hexane, heptane, isoheptane, octane, isooctane, methylcyclopentane, cyclohexane, methylcyclohexane, toluene, etc.
- Alcohols are not specifically limited.
- Preferred alcohols are chain saturated alcohols having about 1 to about 5 carbon atoms, such as methanol, ethanol, n-propanol, isopropanol, n-butyl alcohol, sec-butyl alcohol, isobutyl alcohol, tert-butyl alcohol, pentyl alcohol, sec-amyl alcohol, 1-ethyl-1-propanol, 2-methyl-1-butanol, isopentyl alcohol, tert-pentyl alcohol, 3-methyl-2-butanol, neopentyl alcohol, 2-ethyl-1-butanol, etc.
- methanol, ethanol, isopropanol, n-propanol, etc. are desirable.
- esters are not specifically limited.
- Preferred esters are esters of fatty acids having about 1 to about 5 carbon atoms with lower alcohols having about 1 to about 6 carbon atoms, such as methyl acetate, ethyl acetate, propyl acetate, isopropyl acetate, butyl acetate, isobutyl acetate, methyl propionate, ethyl propionate, propyl propionate, isopropyl propionate, methyl butyrate, ethyl butyrate, methyl valerate, etc.
- methyl acetate, ethyl acetate, propyl acetate, butyl acetate, etc. are preferred.
- ketones are not specifically limited.
- Preferred ketones are those represented by the formula R-CO-R' wherein R and R' each represent a saturated hydrocarbon group having about 1 to about 4 carbon atoms.
- Examples of such ketones are acetone, 2-butanone, 2-pentanone, 3-pentanone, 4-methyl-2-pentanone, etc.
- acetone, 2-butanone, 4-methyl-2-pentanone, etc. are preferred.
- composition of the invention may further contain ingredients heretofore used for this kind of cleaning compositions according to a particular application.
- Useful ingredients are surfactants and like auxiliary agents for cleaning compositions, stabilizers, hydrogen-containing chlorofluorohydrocarbons which would be less likely to destroy the ozone layer, hydrogen-containing fluorohydrocarbons and other hydrocarbons which are entirely free from the possibility of destroying the ozone layer, and so on.
- a conventional cleaning method can be employed.
- cleaning methods include, for example, manually wiping methods, immersion methods, spraying methods, oscillating methods, ultrasonic cleaning methods, steam cleaning methods, etc.
- the cleaning composition of the invention is not prone at all to destroy the ozone layer and is capable of accomplishing effective cleaning for removal of fluxes. Having a proper solvency like that of R-113 heretofore used, the cleaning composition of the invention can selectively dissolve and remove only dirts (including fluxes, fats and oils, dust, etc.) without corroding composite products composed of metals, plastics, elastomers, etc.
- a flux (trade name: Tamura F-Al-4, product of Tamura Seisakusho) was applied on the entire surface of a printed board (copper clad laminate).
- the coated board was preheated at 110°C for 20 seconds and soldering was conducted at 250°C for 5 seconds. After the soldering, the printed board was immersed in the cleaning composition of the invention, followed by one minute of ultrasonic cleaning. The degree of the removal of the flux was evaluated according to the following criteria. Table 1 shows the results.
- a flux (trade name: F-AL-4, product of Tamura Seisakusho) was applied on a printed board (10 cm x 10 cm) and the coated board was preheated at 110°C. Soldering was conducted at 250°C for 5 seconds. A test for ability to remove fluxes was conducted using the cleaning compositions of the invention as listed below in Table 3 by subjecting the printed board treated above to ultrasonic cleaning for 60 seconds and to vapor cleaning for 60 seconds.
- the degree of removal of the flux was evaluated by observing the printed board with the unaided eye and according to the following criteria.
- the amount of ionic residue was measured using an Omega meter 500 (trade name of a product of KENKO) and utilized for evaluation according to the following criterion. Table 3 shows the results.
- Criterion for evaluation by the amount of ionic residue Exhibiting satisfactory ability to remove fluxes when the amount of the inonic residue is up to 2 ⁇ gNaCl/cm2
- a 100 mesh-cylindrical wire net (25 ⁇ x 15 H mm) on which spindle oil was deposited was immersed in the cleaning composition of the invention heated to 60°C, followed by 60 seconds of ultrasonic cleaning.
- the wire net was further immersed in a solvent heated to 40 to 60°C and subjected to shaking with hands or to ultrasonic cleaning for 60 seconds. Thereafter, vapor cleaning was conducted for 60 seconds, whereby the cleaning composition was tested for degreasing ability. After the test, the quantity of oil remaining on the wire net was measured by an oil content meter (product of Horiba, Ltd.) and the degree of removal of oils was expressed in cleaning degree (%).
- Table 4 below shows the composition of the cleaning compositions used and the cleaning degree.
- the cleaning compositions of the present invention are excellent in degreasing ability.
