摘要

PROBLEM TO BE SOLVED: To provide a technique for measuring a time required for plating when throwing powder into an electroless plating solution to perform electroless plating.SOLUTION: The method for measuring a plating time when plating powder in an electroless plating solution comprises: the mixing step of mixing the electroless plating solution including first metal ions with the powder; the sample preparing step of sampling a predetermined amount from the electroless plating solution and separating the powder to repeatedly prepare a sample including the first metal ions at intervals of a predetermined time; the quantification step of quantifying the concentration of the first metal ions included in each sample repeatedly prepared at the intervals of the predetermined time; and the measurement step of measuring the plating time in the electroless plating solution on the basis of the result of the quantification step.SELECTED DRAWING: None
