Umut Tosun, Application Technology Manager, to Present on Static and Dynamic Cleaning Rates at SMTA International 2014

Sep 15, 2014

ZESTRON, the global leading provider of high precision cleaning products, services and training solutions in the electronics manufacturing industry, is pleased to announce that ZESTRON Americas’ Umut Tosun, will be presenting at the SMTA International 2014.  Umut Tosun, M.S.Chem.Eng., Application Technology Manager, will present “Cleaning Process Efficiency and the Influence of Static & Dynamic Cleaning Rates” during the Solder and Cleaning Process Selection and Control session on Wednesday, October 1st.

Speed and efficiency of the cleaning process is critical to the manufacturer’s operation and this is directly related to the cleaning rate of the system. The process cleaning rate is impacted by both the static and dynamic cleaning rate. The SCR (Static Cleaning Rate) is related to the ability of the cleaning agent to solubilize the residues whereas the DCR (Dynamic Cleaning Rate) is related to the effectiveness of mechanical energy imparted by the cleaning system in order to remove the solubilized residues. Is there a real correlation of the static cleaning rate to the dynamic cleaning rate?

Mr. Tosun presents the results of an experimental study designed to explore this relationship. Utilizing bare and populated test vehicles with RMA solder paste, the optimum cleaning agent parameters for the static cleaning rate for two cleaning agents was established. Employing these results, the equipment operating parameters required to optimize not only the dynamic cleaning rate, but overall cleaning process performance were identified. Results of all tests are presented by Mr. Tosun, including conclusions drawn regarding correlations between the static and dynamic cleaning rate, as well as an analytic approach to employing SCR and DCR to select the optimum cleaning agent.
