ZESTRON to Present


Manassas, VA. - September 22, 2009 - ZESTRON America, the world leader in high precision products and services announces that Ravi Parthasarathy, Senior Process Engineer, will present at the upcoming SMTAI tradeshow. The presentation, titled "Why switch from Pure DI-water to Chemistry" is scheduled to take place Tuesday, October 6, 2009 from 10:00am - 11:30am. In this presentation, Ravi will discuss the challenges of DI-water cleaning processes and the limitations the North American market is facing while cleaning with pure DI-water. Further, he will be addressing the importance and necessity of chemistry-assisted cleaning especially when cleaning lead-free solder pastes and non-water soluble residues. The latter are much more difficult to remove. Furthermore, cleaning of water-soluble fluxes in tight spaces is becoming more and more challenging with DI-water only. Its high surface tension with over 70 dynes/cm makes it almost impossible to clean effectively underneath low standoff components.

Concluding, the presentation will demonstrate the value-added benefits of chemistry-based cleaning processes, such as decreasing the overall process cost, better bonding and coating after cleaning, lower application temperatures, and wider process windows.
