 NOTE In this section, typical SL-940E/SL-941E configurations are considered. However,
operational details may vary with the configuration of your system.
5.2 Safety First
Operation of the SL-940E/SL-941E involves heat, air pressure, electrical power, mechanical devices, and
the use of hazardous materials. It is essential that every person servicing or operating the coating system
fully understands all hazards, risks, and safety precautions. Refer to Section 2 - Safety for additional
information.
5.3 Basic System Operation
The SL-940E/SL-941E is a high-speed, high-accuracy coating system with integrated, closed-loop
process control that ensures superior coating quality. Process parameters are recorded and traceable
through Easy Coat (ECXP) software running on Windows XP operating system. Easy Coat for Windows
XP (ECXP) software controls both the robot movements and the dispensing operation.
The SL-940E has a chain conveyor, which carries the workpiece from an upstream machine, to a
dispensing station where fluid is dispensed, and then delivers the processed workpiece to a downstream
machine. The SL-941E is configured with adjustable tooling rails instead of a conveyor. The adjustable
tooling rail is ready to accept boards with a 3mm or greater edge clearance.
5.4 Conformal Coating
The Select Coat SL-940E/SL-941E Series Conformal Coating System is designed to apply conformal
coating materials with a high level of flexibility and consistency. Conformal coating is a material that is
applied to a circuit board to provide protection from chemical and mechanical damage.
Applying conformal coating is a two-step process. Dispensing the conformal coating is the first step.
After the conformal coating has been applied, it must be cured. The curing method depends on the coating
material. Most materials are cured by heat (infrared), UV (ultraviolet light), or moisture (humidity).
