Document Type and Number:
WIPO Patent Application WO/2017/142208
Kind Code:
A1
Abstract:
The present invention relates to a concentration indicator of a metal component contained in a plating solution and a plating method using the same and, more specifically, as the concentration of a plating metal component to be plated is lowered, the color of the plating solution is changed to visually indicate a change in concentration, and thus a worker can readily manage the concentration of a metal component contained in a plating solution within a short time. In addition, whether a plating metal component should be replenished can be determined in real-time so as to enable the precision and reliance of plating work to be improved, workability is improved by continuous maintenance, and cost is reduced.
