CAPABILITY THE PROBLEM Low yields of gold-plated lead frames. The manufacturer was dissatisfied with the efficiency of his goldplating bath and suspected that the ratio of Au* to A u " in the bath was incorrect.
monitors the concentration of his cobalt brighteners and detects surface con-. taminants left behind after surface pretreatment.
THE SOLUTION Analysis of the bath by a Dionex Ion Chromatograph™ Results were obtained in 12 minutes, following a simple dilution. These showed that the concentration of Au(CN)"4 was too high. The concentration was lowered and Ion Chromatography was used from that point on to monitor and optimize the efficiency of the bath. The manufacturer now also
