-In the case of trichloroethane, strict reduction of its use as a causative substance that destroys the ozone layer has to be made, and since it has become impossible to use it for the cleaning, an alternative cleaning agent has been widely demanded. For alternative cleaning, alternative CFCs with or without ozone depletion potential, water-based cleaning agents containing alcohol or hydrocarbon oil as a main component, or water-based cleaning agents containing alkali as a main component have been widely proposed. However, these CFC cleaning alternatives have not reached a level that is sufficiently satisfactory in terms of safety, cleaning performance, and economical efficiency, and alcohol (system) cleaning has a low flash point, leaving concerns about operational safety. However, the water-based cleaning mainly composed of hydrocarbon oil or the water-based cleaning agent mainly composed of alkali has a problem that selectivity of the material to be cleaned, that is, influence on the material to be cleaned is concerned.

ックスの付着した基板の洗浄処理を行う。The present invention has been made focusing on such conventional problems. That is, 60 parts by weight to 95 parts by weight of an alkylene oxide adduct of an aliphatic saturated alcohol having 1 to 4 carbon atoms and / or an aliphatic unsaturated alcohol having 1 to 4 carbon atoms, and castor oil polyethylene glycol ester of HLB 8 to 12 And / or a higher fatty acid polyethylene glycol ester having 6 to 22 carbon atoms in an amount of 5 to 40 parts by weight. (Requirements Constituting Means) The cleaning composition of the present invention is a mixture of an alcohol component (hereinafter referred to as A component) and an ester type nonionic surfactant (hereinafter referred to as B component). As the component A, an alkylene oxide adduct of an aliphatic saturated alcohol having 1 to 4 carbon atoms and / or an aliphatic unsaturated alcohol having 1 to 4 carbon atoms is used. The aliphatic saturated alcohol having 1 to 4 carbon atoms includes methyl alcohol, ethyl alcohol, propyl alcohol and butyl alcohol, and the aliphatic unsaturated alcohol having 1 to 4 carbon atoms includes allyl alcohol, propargyl alcohol and the like. To be Examples of the alkylene oxide to be additionally synthesized with the alcohol include ethylene oxide, propylene oxide and butylene oxide, and the number of addition moles thereof is preferably 1 to 5 moles. Any of these alkylene oxides may be added alone or used in combination for addition synthesis. The amount of the component A is 60 to 95 parts by weight in the composition,
If it is less than 60 parts by weight or more than 95 parts by weight, the cleaning property is deteriorated when the cleaning liquid deteriorates. Next, B component is an ester type nonionic surfactant,
Castor oil polyethylene glycol ester of B8-12 and / or polyethylene glycol ester of higher fatty acid having 6-22 carbon atoms of HLB8-12 are used. Examples of the higher fatty acid having 6 to 22 carbon atoms include higher fatty acids such as caproic acid, lauric acid, stearic acid and oleic acid, which may be used alone or in combination. The polyethylene glycol ester may be produced by adding 3 to 30 mol of ethylene oxide to castor oil and / or higher fatty acid, or may be produced by first polymerizing ethylene oxide and then performing an esterification reaction. The content of the component B is 5 to 40 parts by weight in the composition. If it is less than 5 parts by weight, the detergency upon deterioration is inferior, and if it exceeds 40 parts by weight, the general cleaning is inferior. Further, the HLB of the component B must be 8 to 12, and when the HLB is less than 8, the cleaning property is generally poor,
In particular, the washability during deterioration is significantly reduced, and when the HLB exceeds 12, the washability is generally poor. The cleaning composition of the present invention is used as it is or diluted with water, and the substrate to which the rosin-based flux is adhered is cleaned based on a cleaning method such as dipping, ultrasonic wave or spraying.

となる。The cleaning composition of the present invention is a water-soluble cleaning composition used for cleaning rosin-based flux such as CFC-113 or 1,1,1-trichloroethane and does not contain any substance causing ozone layer depletion, and is alcohol-based. Compared to detergents, it has a high flash point, is easy to handle, and has an excellent cleaning effect and life. Compared to water-based detergents, it is safe to handle and has excellent cleaning properties and cleaning life. Furthermore, since it is easy to wash with water, it becomes easy to wash the rosin-based flux that adheres to the substrate that is becoming finer.

チング影響が著しく実用的な洗浄に適さない。Effect example-1 (ultrasonic cleaning) Oily flux adhesion model substrate with each cleaning agent in Table-1
After ultrasonic cleaning and ultrasonic rinsing at 60 ° C. for 60 seconds and drying, the residual flux was measured by an ultraviolet spectrophotometric method, and the cleaning (%) was calculated by the following formula. (However, CFC-113 is cleaned at 30 ° C.) Effect example-2 (spray cleaning property) 2 kg / cm 2 was changed to ultrasonic cleaning under the same conditions as in effect example-1.
Perform pressure spray cleaning. The evaluation method is represented by the detergency (%) similarly to the effect example-1. Effect example-3 (deterioration cleaning property) 20% of the oily flux to be cleaned is added to each cleaning composition shown in Table 1 to make a deterioration cleaning liquid, and the same operation as in effect example-1 is performed to measure the deterioration cleaning liquid cleaning effect. To do. The cleaning compositions 1 to 3 of the present invention have excellent effects on any cleaning property. On the other hand, regarding the comparative cleaning composition, (a) and (b) show a slight decrease in ultrasonic and spray cleaning properties, and a marked decrease in deterioration cleaning property. In (c), the carbon number of the alcohol of the component A was large, and the effect was remarkably reduced. In the case of (d), since the HLB of the B component is low, the deteriorated cleaning property is particularly poor. In (e), since the HLB of the B component is high, it can be seen that the cleaning property is generally deteriorated. Since (f) and (g) have different compositions of the component B, the detergency is generally low, and the deteriorating detergency is particularly low. (H) is a substance causing ozone layer depletion, although it has excellent cleaning properties. Regarding (i), there is a concern that the flash point is low, and the performance is deteriorated when deteriorated. (No.) has problems of low spray cleaning performance and large deterioration of performance when deteriorated. (L) is not suitable for practical cleaning because the deterioration of the performance at the time of deterioration and the etching effect on the solder part are significant.
