3.1 Overview
This section provides film coater operating procedures. For complete system operating procedures, refer
to the applicable coating system manual. This section covers the following topics:
•Theory of Operation
•SC-10X Features
•Feature Description
•Startup
•Shutdown
3.2 Safety First
Operation of the SC-10X film coater involves air pressure, electrical power, mechanical devices, and the
use of hazardous materials. It is essential that every person servicing or operating the coating applicator
fully understands all hazards, risks, and safety precautions. Refer to Section 2 - Safety for additional
information.
NOTE A purge program is necessary to properly purge the film coater before and after use.
For SC-10XHS Film Coaters, the program must include a routine for purging the tilt
mechanism. For assistance in writing this routine, refer to the Easy Coat User Guide or
contact your Asymtek representative.
WARNING! CAUTION!
Consult the Material Safety Data Sheet (MSDS) for all fluids used with the
dispensing system. The MSDS provides material usage instructions, disposal
instructions, and safety precautions.
CAUTION! Do not expose the solenoid valve to solvents or coating material. Solvents could
damage the valve, and coating material may clog it.
3.3 Theory of Operation
The SC-100HS film coater is moved by a gantry robot horizontally along the X and Y axes, and vertically
along the Z axis. Both the SC-104/105HS film coaters are fitted with air-actuated rotary cylinders, which
rotate the nozzle in 90º increments. In addition, the SC-105HS is equipped with a small mechanical lever
at the base of the film coater that tilts the nozzle from vertical to 30º from vertical.
The SC-100 Series Film Coater is air-actuated and the piston and needle travel is micro-adjustable for
precise pattern and film-thickness control. The SC-100HS upper-body module consists of an air cylinder
and piston, and air and fluid seals. A micro-adjustment mechanism controls piston travel. The SC-100HS
lower-body module is equipped with fluid passages and an extension for mounting a nozzle. The nozzle
accommodates both Asymtek Cross-Cut and ribbon nozzles.

Operation 11
3.5 Feature Description
3.5.1 Micro-Adjustment
The piston and needle travel is adjusted by rotating the micro-adjustment cap screw at the top of the film
coater. Rotating the micro-adjustment cap clockwise decreases the piston and needle travel, decreasing
the amount of coating material allowed to flow through the seat. Rotating the micro-adjustment cap
counterclockwise increases the piston and needle travel, increasing coating material flow.
3.5.2 Air Inlet
Trigger air enters the film coater from the solenoid valve on the manifold; through the air inlet. The trigger
air then travels upward through the bore and presses against the piston. Air pressure forces the piston
upward to overcome the downward pressure exerted by the spring washers. A seal on the piston and an
O-ring on the piston retainer help prevent trigger air from leaking past the piston. Any air that does leak
past the piston is vented through the weep hole in the side of the film coater cap.
3.5.3 0-90° Rotate Mechanism (Fourth Axis)
A rotary air cylinder activates, causing the extension and nozzle to rotate 90º. When the rotary cylinder air
is exhausted, the extension and nozzle are rotated back to the original position.
3.5.4 Rotate and Tilt Mechanism (Fifth Axis)
The tilt mechanism is available on the SC-105HS Film Coater only. Two rotary cylinders are coupled
together to provide four 90° indexed positions. Air activates a cylinder located on the manifold, causing
the tilt mechanism to activate. The cylinder arm extends or retracts, moving a sleeve on the extension up
or down. This motion is transferred to the tilt lever, which tilts the nozzle from 0° to 30°.
3.5.5 Piston and Needle
The piston is forced upward by the trigger air until it comes in contact with the micro-adjustment cap
screw. The needle attached to the piston pulls away from the seat, which allows coating material to flow
through the opening in the seat. Air that may leak past the hat seals is vented out the weep hole in the
upper-body module (between the hat seals and the U-cap seal).
3.5.6 Fluid
Pressurized coating material enters the lower-body module through the fluid inlet, flows into the extension
through the seat and out through the nozzle. Unused coating material flows through a bore in the center
of the needle into the upper-body module to the fluid outlet.
3.5.7 Solenoid Valve
A normally closed air solenoid valve is mounted on the film coater manifold. When 24 Vdc is supplied to
the valve, it opens, allowing air in to trigger the gun. Mounting the solenoid valve directly on the manifold
provides a quick response time for short-duration dispense operations.
3.5.8 Mounting
A mounting block and manifold mounts the film coater on the head of the gantry robot. Locating holes are
provided for positioning the film coater. Two #8-32 (C-74X) or two M4 x.7 (SL-94XE) machine screws
secure the film coater to the robot.

3.6 Startup
To start film coater operation:
1. Start the coating system. Refer to the applicable coating system manual for instructions.
2. Make sure the nozzle nut or nozzle holder is wrench-tightened onto the film coater extension.
If applicable, make sure the tilt mechanism moves without binding.
NOTE A purge program is necessary to properly purge the film coater before and after
use. A purge routine is included in the software. A purge routine is included in the
Easy Coat Software. For assistance in running this routine or writing a
customized routine, refer to the Easy Coat User Guide or contact your Asymtek
representative.
3. Place a small waste container under the end of the extension to catch coating material.
4. Start the Easy Coat for Windows XP software.
5. Start the purge program.
If the film coater is equipped with a tilt mechanism (SC-105), operate the tilt mechanism
several times while purging to clean all material from the nozzle holder O-ring. Failure to
do so will result in early O-ring failure.
6. After running the purge program, remove the waste container.
7. Check the production planning log to determine the proper nozzle to be used. Screw the
proper nozzle into the nozzle nut or nozzle holder.

14 Operation
3.7 Shutdown

a. Disconnect the tilt link from the tilt lever.
b. Remove the tilt mechanism from the extension.
5. Remove the nozzle holder or the nozzle nut and the nozzle from the extension. Immerse the
parts in the appropriate cleaning solvent.
CAUTION! Use an Asymtek nozzle brush to scrub the nozzle. Do not use a steel brush or any
other type of brush that will damage the nozzle carbide tip.
NOTESIf the nozzle orifices are blocked, insert a probe or broach into the orifice
against the direction of fluid flow. Do not twist the probe or broach or try to
clean the orifice with a sawing motion.
If the nozzle, nozzle nut, or tilt mechanism are not properly cleaned, coating
material will build up over time and clog the nozzle orifice. This will result in
restricted or blocked flow or pattern alteration. If this problem occurs, immerse
the nozzle, nozzle nut, or tilt mechanism in an appropriate solvent (such as
MEK). Soak the nozzle, nozzle nut, or tilt mechanism overnight before cleaning.
6. Dry the nozzle, nozzle nut, or tilt mechanism and inspect the orifices for any blockage.
7. Reinstall the parts, or store all removed parts in a safe place.
