This section introduces options that are currently available for the Century C-740/C-741 Series Dispensing System. 3.8.1 Bar Code Recognition System The Bar Code Recognition System uses a bar code label mounted on the workpiece to select the appropriate coating sequence.
3.8.4 Dual Simultaneous Mounting Bracket The Dual Simultaneous Mounting Bracket, mounted on the Dispensing Head, doubles dispensing capability by accommodating two identical applicators side by side for simultaneous dispensing of a single fluid. The two applicators are controlled independently by ECXP, enabling one coating sequence to coat one or two products at a time. The system is configured for your specific application. Figure 3-2 Dual Simultaneous Mounting Bracket 3.8.
3.8.6 Laser Fan Width Control System Laser Fan Width Control provides closed-loop control of the conformal coating process, automatically compensating for variables within the process environment that can affect fluid fan width. Fan width programming, accomplished through the ECXP software, can be retrofitted to existing Century Series Dispensing Systems equipped with the SC-105 and SC-205 Film Coater Modules.
3.8.7 Flow Monitoring System The Flow Monitoring System monitors the volume of material dispensed. The dispensing system can be programmed to stop, pause, or continue when the dispensed volume falls outside the preset range. In operation, the Computer controller, together with ECXP software, monitors the gear-type Flow Meter when the coating sequence begins. ECXP software records the data in a log file and displays it on the Monitor in bar graph format with time history. Figure 3-4 Flow Meter 3.8.
3.8.10 Inline Inverter Module The Inline Inverter Module provides for a “true” inline process by virtually eliminating manual handling of the workpiece. Automatic one-or two-sided conformal coating reduces board-handling requirements and increases yield. The Inline Inverter Module is SMEMA compatible and features a ventilated and interlocked enclosure. The Inline Inverter Module can be configured for four modes of operation: 1.
3.8.11 Light Curtain The Light Curtain is an optional substitute for transparent front doors. To detect obstructions, the Light Curtain uses an emitter and a receiver.

3.9.2 SC-104HS/SC-105HS High Speed Circulating Film Coater The SC-104HS (4-axis) and SC-105HS (5-axis) apply coatings in a film rather than in an atomized spray produced by conventional airless spray guns. The coaters are fitted with an air-actuated rotating ring mechanism, which rotates the nozzle in 90-degree increments. In addition, the SC-105HS has an airactivated tilt assembly, which allows the stroke to be adjusted from vertical to 30 degrees from vertical.
3.9.3 SC-10XVCS Viscosity Control System The Viscosity Control System maintains consistent temperature of conformal coating fluids. The system includes a fluid dispensing applicator and a heated recirculating fluid circuit to eliminate viscosity changes in temperature-responsive materials. Close-range temperature monitoring keeps the coating process consistent and stable. By controlling the temperature of the conformal coating fluid circuit, viscosity fluctuations can be reduced.
3.9.4 SC-200 Slim Swirl Applicator The Select Coat Slim Swirl Applicator (SC-200) uses Nordson slim swirl 12-hole nozzles to apply materials that do not require heating and therefore do not require circulation. It is air-actuated and the piston and ball travel is micro-adjustable for precise pattern and film-thickness control.
3.9.4.1 Tri-Mode Swirl Box The Tri-Mode Swirl Box is a component of the SC-200 Slim Swirl Applicator. It has two air assist and two fluid regulators and gauges, which regulate the fluid and air-assist pressure to the Fluid Dispensing Applicator. By varying the fluid pressure, conformal coating materials can be dispensed in a bead, monofilament, or swirl pattern. • Bead - A non-atomized stream is applied to areas where: Components are close to keep-out areas. Extra material is required.
3.9.5 SC-204HS/SC-205HS High Speed Non-Circulating Film Coater The SC-204HS (4-axis) and SC-205HS (5-axis) film coaters are used to apply materials that do not require heating and therefore do not require circulation. The coaters are fitted with a rotating ring mechanism, which rotates the nozzle in either a 0-degree or 90-degree position. In addition, the SC-205HS has an air-activated tilt assembly, which allows the stroke to be adjusted from vertical to 30 degrees from vertical.
3.9.6 SC-300 Swirl Coat Applicator The SC-300 Series Swirl Coat Applicator is a non-contact coating applicator providing high-speed delivery and exceptional volumetric control for various fluids, especially “100%-solids” formulations. The SC-300 coats in tight spaces and has unequalled versatility for spray pattern flexibility under program control. The tri-mode operation refers to the combination of fluid and air-assist control. With the air-assist off, the SC-300 dispenses fluid in spots or beads.

6.4 Detailed Operation (C-740) During operational setup of the C-740 inline system, the part enters the system using SMEMA (Surface Mount Equipment Manufacturers Association) handshakes. It moves to the dispensing area where the conformal coating is applied and then exits the system. Conformal coating application programs are created using the Easy Coat for Windows XP (ECXP) software installed on the system. 6.4.
Production Run Started Operator enters ECXP Command “Start Production.” Part Enters the System 1. If system dispense part sensor is clear, then system sends SMEMA signal to upstream machine – “Request for Board.” 2. Stop Pin lowers. 3. When upstream machine is ready, it sends SMEMA signal to dispensing system – “Board Ready to Send.” 4. While both SMEMA signals are high, the Conveyor indexes part toward dispensing area. 5. Part Sensor detects part. 6. Conveyor stops. 7.
6.5 Computer System The computer is located inside the lower cabinet. The CD-ROM drive, disk drive, power switch and reset buttons are located on the front of the computer. Access to connections at the rear of the computer should be limited to service technicians. Conformal coating dispensing programs are created using the ECXP software installed in your system. Dispensing programs are stored on the computer hard drive. 6.5.

Bead Mode: Conformal coating applied in a nonatomized stream. Available with the SC-200 Slim Swirl Applicator and Tri-Mode Swirl Box. Curing Process: The second step in the Conformal Coating process. After a coating material has been applied, it must be cured (hardened). Current: The flow of electrons through an electrical circuit.
ESD: Electrostatic Discharge. Exhaust Vent Duct: The Exhaust Vent Duct is connected to the facility exhaust system ductwork and removes fumes from the dispensing system. Fixture: Location at which products are physically constrained in the workcell. Consists of both a position (X, Y, Z) and a corner constraint. Flexible IR/Convection Module: Asymtek's inline forced-convection cure module features a flexible design ideal for mid- to high-volume production. Coating materials are cured using infrared heat.
Low Fluid Sensor: Triggers a Light Beacon display or software error message when the level of coating material is low. Main Air Inlet: The Main Air Inlet connects the Century Series Dispensing System to your facility air supply. Main Power Inlet: The Main Power Inlet connects the Main Power cable from the facility power source to the dispensing system. Maintenance: Planned or unplanned activities intended to keep the dispensing system in good working order.
SC-105HS High Speed Film Coater: Asymtek 5-axis circulating Fluid Applicator, with a 0-360° rotate mechanism plus tilt, that applies conformal coating in a film rather than an atomized spray. Tool Offset: The tool offset is the X, Y, and Z distance from the Robot's lower tooling pin to the tool tip (the end of the nozzle). Robot position is calculated using the coordinates of the tooling pin plus the offset.
