を解明し遂次新規追加して安定管理を狙ってbた。Conventionally, when potassium persulfate is used as an oxidizing agent in the blackening treatment solution for steel foil in the manufacturing process of printed circuit boards, the composition of the solution can be stably controlled by self-decomposition of the oxidizing agent in the solution. It is difficult to remove the oxidizing agent by discarding the liquid after each patch treatment, or by discarding 1/3 to 1/2 of the liquid cap at a certain processing time and adding the discarded portion, or by manual analysis. We clarified the decreased value and added new ones one after another, aiming for stable management.
