1 Introduction

1.1 Overview

The Select Coat

SL-940E/SL-941E Series Conformal Coating Systems are designed to provide the

highest quality and productivity for automated coating processes. This manual is intended primarily as a

reference for production operators, process engineers, and service technicians. However, others

unfamiliar with Asymtek products may also find this manual useful as a general introduction to the

system. This section covers the following topics:

• Manuals Supplied

• Training

• Standard Equipment

• Optional Equipment

• Conformal Coating Applicators

• System Features

1.2 System Description

The SL-940E/SL-941E systems provide consistent, uniform dispensing of a variety of conformal coating

materials for both conveyorized (SL-940E) and batch (SL-941E) coating applications. These coating

systems are high-speed, high-accuracy conformal coating systems 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. The system can eliminate the

requirement for labor-intensive board masking, providing accurately controlled patterns, film builds, and

production flexibility in an automated process. Film thickness is achieved in a single pass with little or no

masking and with virtually no overspray.

1.3 Safety First

Operation of your SL-940E/SL-941E involves heat, air pressure, pneumatic devices, electrical power,

mechanical devices, and the use of hazardous materials. Read this manual in its entirety before attempting

any system or component operation. It is essential for all personnel working on or around the coating

system to fully understand the hazards, risks, and safety precautions associated with operating the system.

When properly operated and maintained, the coating system is safe and reliable. Refer to Section 2 -

Safety for additional information.

WARNING! CAUTION!

Consult the Material Safety Data Sheet (MSDS) for all fluids used with the

coating system. The MSDS provides material usage instructions, disposal

instructions, and safety precautions.

1.4 Facility Requirements

To ensure optimal performance and safety, it is necessary to install the coating system and its components

in a facility that meets the requirements listed in Section 10 - Specifications. If you have any questions

about facility requirements, please contact Asymtek Technical Support.
