Asymtek Select Coat SL-940E Conformal Coating Platform Incorporates Vision, Closed-Loop Process Controls, Precision, and Traceability in a High-Speed System
 Carlsbad, CA – November 6, 2007 – Asymtek, a Nordson company and leader in coating, dispensing, and jetting technologies, introduces its next generation conformal coating platform, the Select Coat® SL-940E, at Productronica, Stand A4.340 in Munich, Germany from November 13 – 16, 2007. With up to 30 percent faster throughput, a vision system, closed-loop process controls, traceability, and advanced integrated software, the Select Coat SL-940E provides high quality and increased productivity in a high-speed, high-accuracy coating system.
With the Select Coat SL-940E, advanced monitoring makes it easier to keep the coating process in control. Fluid and air pressures are set and monitored through software-controlled electronic regulators, allowing traceability for these critical parameters. Data logging and automatic adjustments of other parameters such as fan widths and fluid temperatures further ensure the quality of the coating process.
The new, faster motion system of the SL-940E unleashes the performance capability of Asymtek’s SC-104/204 Film Coater applicator, attaining 750 mm per second speed and 1 g peak acceleration. It accommodates product sizes up to 500 mm for higher speed and faster cycle times. The welded one-piece structure of the frame enables high acceleration and velocity with up to 2.5 kg payload. Rotary encoders deliver high levels of positional accuracy for precise coating operations.
The SL-940E has a large dispense area of 500 x 475 mm (19.7 x 18.7 in.). The enlarged work area enables flexibility during production to add multiple board arrays or to coat large substrates. Programming is made easier with the optional camera and pattern recognition system. The controls of popular options like Asymtek’s Laser Fan Width Control, Viscosity Control System, Bar Code System, and Flow Monitoring have been fully integrated within the machine for a more seamless operation.
A variety of fluid delivery options are available to accommodate a wide array of fluids and applications. These include the heat circulating Viscosity Control System (VCS) and the SC-204 and SC-205 film coater modules, both of which are non-atomizing systems. The Swirl Coat SC-300 applicator is a three-mode swirl system, while the PreciseCoat™ SC-400 Jet Applicator can be used for high selectivity applications.
The Select Coat SL-940E system is designed with safety in mind. Downdraft and spill containment are integrated into the new platform. The downdraft ventilation provides an efficient path for volatile organic chemical (VOC) removal. With internal stainless steel surfaces, the system is easy to clean and resistant to strong agents. Asymtek’s conformal coating system has been independently tested and certified for compliance with relevant safety standards including CE, and SEMI.
