不利を解消している。(Prior Art) Rosin-based solder flux is used in the production of modules such as printed circuit boards and printed wiring boards. The purpose of soldering is generally to increase the adhesive strength between the board and the input/output bottle, and to prevent oxidation of the contacts and maintain conductivity. type solder flux is used. After soldering is completed, a cleaning agent is used to selectively and completely remove only the flux from the board surface. In other words, if the flux is not sufficiently cleaned, the residual flux may cause circuit corrosion, or the electrical insulation of the board surface may deteriorate.
This has the disadvantage of ultimately leading to circuit damage. Therefore, the disadvantages mentioned above are overcome by using cleaning agents to remove the residual flux, especially the activator components contained therein.

。Conventionally, halogenated hydrocarbon solvents such as so-called chlorofluorocarbons such as trichlorethylene and trichlorotrifluoroethane have been used as cleaning agents for rosin-based solder flux. However, due to environmental pollution problems such as ozone layer depletion, restrictions on the use of such halogenated hydrocarbon solvents are becoming more serious, and the development of so-called fluorocarbon substitute cleaning agents for solder franking has become an urgent need in the electronics industry. .

されるなどの不利がある。Recently, various non-halogen solder flux cleaning agents have been developed. For example, in the case of alkali saponification type,
Since it is an aqueous solution type, there is no problem with flammability, but there are disadvantages such as low cleaning efficiency as it requires contact with the liquid for a long time under heating, and furthermore, there is a concern that the metal parts of the board may corrode. be.
