ツキが生じている。(Prior art and its problems) In the manufacturing of printed circuit boards, etc., 1.1.1-) Solvents such as dichloroethane and methylene chloride are used to clean the surface of the board and other substances. As operation continues, the solvent becomes contaminated and it becomes necessary to regenerate it. The regeneration step is a step in which the solvent in the cleaning step is partially extracted as a waste liquid, and the waste liquid is heated to vaporize and condense the solvent components and return to a clean regenerated liquid from which impurities have been removed. However, in conventional regeneration operations, it is not possible to grasp the amount of regeneration (capacity) in the regeneration process, so the amount of waste liquid extracted from the cleaning process and the amount of regenerated liquid supplied cannot be balanced, and the interval between maintenance of the regeneration equipment is ambiguous. Maintenance is performed at regular intervals regardless of capacity or contamination status. Therefore, the quality of the solvent used in the cleaning process is not constant, and the quality of the manufactured printed circuit boards also varies.

じ品質への信頼性が低下することになる。The regeneration capacity of the regeneration device varies depending on the amount of heat applied, the contamination status of the waste liquid, etc. Therefore, if a certain amount of waste liquid is extracted at regular intervals, regenerated by a regenerating device, and reused for circulation, the state of the recycled solvent will change, and if the solvent is used, for example, to clean printed circuit boards, the quality of the printed circuit boards obtained will vary, resulting in a loss of confidence in quality. This will result in a decline in sexuality.
