Analysis of eluted components from printed circuit boards.
It is possible to analyze cation components in liquid samples.
As electronic devices are increasingly used in various everyday locations, ensuring the reliability of products has become important. Since it is possible for the copper used in the wiring of printed circuit boards to migrate and cause defects in high temperature and high humidity environments, it is crucial to evaluate the components that promote migration. This case study introduces an example of quantitative analysis of cation components eluted from printed circuit boards using ion chromatography (IC). Thus, IC is an effective method for evaluating the corrosion components on the surface of solid samples.
