Asymtek's New Viscosity Control System™ for Consistent & Stable Conformal Coating Results
Carslbad, CA - Asymtek’s new Viscosity Control System™ provides continuous viscosity management to maintain consistent delivery of temperature-responsive conformal coating fluids. The new Viscosity Control System™ combines a heated, recirculating fluid circuit with close-range temperature monitoring to keep the coating process consistent and stable. Solvent usage may be reduced, resulting in less Volatile Organic Compound (VOC) emissions. The Viscosity Control System is an option for the Asymtek Century® Series Conformal Coating platform.
Certain factors like ambient temperature changes and different material lots can cause viscosity fluctuations, which affect the performance and consistency of coatings applied to printed circuit board assemblies. With Asymtek’s Viscosity Control System, fluid delivery is monitored closely and maintained at set parameters. When a user loads a new batch of fluid in a coating system, the Viscosity Control System brings the fluid up to optimal coating temperature. Fluid is continuously recirculated past strategically located temperature probes that control the temperature to within 1 degree Celsius. Safety is designed into the system by using components that meet the most stringent standards for use around volatile materials.
Asymtek supplies award-winning automated fluid dispensing systems that are focused on advanced technology applications in a wide range of industries, including semiconductor packaging, printed circuit board assembly, flat panel display assembly, electronic component assembly, medical/biotech product assembly, and other assembly processes. With over 20 years of experience, Asymtek is committed to providing innovative dispensing solutions and the best support to customers worldwide.
