- AB-420Determination of suppressor with CVS using the calibration technique «smartDT» with dynamic addition volumes
The Application Bulletin describes the determination of suppressor in acid copper baths by smartDT. The determination of suppressor with dilution titration (DT) involves numerous additions with standard solution or sample to reach the evaluation ratio. Usually fixed, equidistant addition volumes are used. With smartDT, variable addition volumes are used that are dynamically calculated by the software. At the beginning, the volumes are bigger. Towards the evaluation ratio, the addition volume becomes smaller to guarantee a good accuracy of the result. The operator defines the first and the smallest addition volume to be used. All volumes in between are calculated by the software considering the progress of the determination. The time saving with smartDT compared to a classic DT with fixed addition volumes can be up to 40%. smartDT is suitable for nonlinear regression and quadratic regression as well as linear interpolation. It can be used for determination of suppressor in acid copper baths as well as in tin and tin-lead baths and works with 1, 2, and 3 mm Pt working electrodes. A 800 Dosino is required for the automatic addition of suppressor standard or sample. The method can also be used in fully automated systems.

- WP-051Automated CVS method development and optimization of multicomponent plating baths
For the past three decades, Cyclic Voltammetric Stripping (CVS) has been the standard practice for analyzing organic additives in electroplating copper baths in the circuit board and wafer plating industries. The variations in the compositions of such baths have created a need for more optimized method development routines. New advancements in the hardware and software protocols for CVS have simplified the overall process of method optimization to a great extent. In this study, the process of method optimization is discussed in conjunction with these protocols.
