New application tracker:✅ brightRC – Advanced brightener analysis with a response curve https://bit.ly/3RFPdi7 Reliable additive control is essential in acid copper plating processes. Cyclic Voltammetric Stripping (CVS) is the industry standard technique to monitor the concentration of organic additives in copper plating solutions. For brightener (accelerator) type additives, the copper stripping signal increases with increasing additive concentration. Therefore, brightener determination is generally performed using standard addition techniques such as MLAT or LAT. These require standard additions for each sample and rely on linear response behavior, limiting analytical flexibility and increasing analysis time. External calibration eliminates the need for repeated standard additions, enabling reliable analysis of brighteners that display nonlinear response behavior. The so-called response curve (RC) calibration approach allows the use of flexible regression models, improving electroplating process control efficiency. This functionality is available as a native feature in our CVS software, viva 4.0 and up.
