The electronics industry‘s demand for error-minimised production processes, continuous quality assurance and low field failures is subject to an ongoing improvement process. The need for reliable and meaningful test methods to achieve these demands is therefore imperative. In this context, the ROSE test has been considered a rapid and reliable analytical method for decades. For the first time, ion chromatography provides an advanced method to set ROSE limit values.
