において、めっき液に補給液を供給する手段としては定
量ポンプが使用されている。When using a plating solution, especially an electroless plating solution, metal salts, reducing agents, etc. are consumed in a short period of time, and the composition of the solution fluctuates rapidly. An automatic control device or method has been proposed (Japanese Unexamined Patent Publication No. 53-44434, 53=4563
No. 1, No. 54-8123, etc.), but in these automatic control devices, a metering pump is used as a means for supplying replenishment liquid to the plating solution.
しかし、定量ポンプは、最近においてがなり精密なもの

しも満足し得ない上、定量設定操作、その制御にも常に
注意を払わなければならず、また定量設定操作の際にミ
スを伴なうおそれがあり、その扱いに問題がある。However, recently, more precise metering pumps have been proposed, but these are expensive, and the general-purpose ones tend to break down in the field, and their quantitative performance is not always satisfactory. In addition, careful attention must always be paid to the quantitative setting operation and its control, and there is a risk of mistakes occurring during the quantitative setting operation, which poses problems in handling.
そして、定量ポンプが故障したり、その定量設定操作に
ミスを伴なったりすると、めっき液に補給液が過剰にも
