GENERAL
DESCRIPTION
Models
RC-801 and RC-802 pulsed
Ultraviolet (UV) light
curing systems are modular,
high intensity light
sources designed for
a wide range of tough
industrial curing applications
that can not be solved
with mercury UV systems.
Featuring high intensity
pulsed UV light lamps
(mercury free) with
single or dual lamp
operation, a high speed
controller with instant
on/off control, and
a high voltage power
supply. Pulsed UV light
is a safe, environmentally
benign and flexible
technology that can
be applied in continuous
and batch curing applications.
RC-801 and RC-802 offer
solutions for demanding
inline curing applications
when low heat and fast
throughput are required.
These modular systems
are designed to function
as part of an integrated
manufacturing system
and provide controlled
high peak power pulsed
UV light. System interfacing
is handled with low
voltage I/O using a
Programmable Logic Controller
(PLC).
ROBUST
DESIGN
RC-801
and RC-802 are designed
for demanding inline
process systems that
must operate continuously
(24/7), producing high
yields and minimum downtime.
Incorporating an optically
isolated I/O interface,
high noise immunity
24Vdc logic, extended
life components, reliable
lamp trigger control
|
|
and
power-on delay, avoiding
high voltage damage
due to line surges,
the RC-800 series offer
long-term reliable operation.
To minimize downtime
during routine maintenance
periods, critical components
such as the lamp housing
optical reflector and
lamp are easily replaced
by plant personnel.
PROCESS
FLEXIBILITY
RC-801
and RC-802 are highly
flexible, robust, modular
curing systems capable
of configurations matching
different curing requirements.
To ease integration,
system configuration
options include single
or dual lamp operation,
lamp housing, lamp spectra,
high voltage power supply,
lamp pulse energy, lamp
pulse rate, light blocking
filter, and various
lamp housing cable lengths.
Installation requirements
are minimized because
there are no requirements
for external water cooling
equipment, mechanical
shutters or motors to
rotate the substrate
during the curing cycle.
Only air cooling to
the lamp housing is
required.
DUAL
LAMP CONFIGURATION
Model
RC-802 adds dual lamp
operation to the benefits
of fast pulsed UV light
curing technology. Each
lamp is individually
sequenced by the controller’s
high speed logic. In
applications such as
optical disc bonding,
multiple lamp operation
with a single electronics
control unit and a single
power supply, offers
tilt management during
batch processing. Additionally,
multiple lamps offer
top-down, bottom-up
or both curing configurations
resulting in higher
throughput with low
substrate temperature.
The individual lamps
respond automatically
to the programmed trigger
pulses and deliver the
full energy with each
pulse.
INTERWEAVE™
TECHNOLOGY
The
RC-800 InterWeave™
controller is designed
to operate a dual lamp
RC-802 system in a predetermined
sequenced flashing mode.
Both the lamps are flashed
at the full programmed
frequency, delivering
full power to each lamp
from a single power
supply.

LITEMARK-XL
The
LiteMark-XL Pulsed UV
Detection System is
an add-on module for
Xenon’s lamp housings.
This module allows real-time
performance monitoring
of radiant energy from
a Xenon Pulse UV Lamp system,
making it easy for the
user to obtain instantaneous
data for process monitoring
and control.
DATA
LOGGER
To
continually monitor
the Pulse UV Lamp process,
the LiteMark-XL may
be ordered with a Data
Logger system. This
system provides both
the hardware to connect
the LiteMark-XL to a
computer, as well as
software programs to
display and record light
intensity data. The
system operator can
observe the data on
a computer monitor as
either tabulated data
or as a graph.
REDUCED
CURE TIME
Cure
time is directly related
to the total UV energy
dose delivered by the
lamp to the target.
Tests have shown there
is an optimum total
energy required to insure
complete cures without
substrate damage. To
reduce the cure time,
while providing the
required energy dose,
models RC-801 and RC-802
are available with lamp
pulse rate options.
Also available are high
voltage power supply
options capable of providing
the required energy
for each option.

BURST
MODE OPERATION
The
instant ON/OFF control
of the pulsed UV lamp
provides the means to
operate in a burst mode
as illustrated in Figure
2. This operation matches
typical start-stop-start
manufacturing. The user
can typically program
the lamp duty cycle
from 1 pulse to 100%.
Maximum duty cycle is
dependent upon the pulse
energy selected.

in batch or index operation
to bond top and bottom
plastic containers.
REDUCED
ENERGY CONSUMPTION
In
typical start-stop-start
manufacturing operations,
the pulsed UV lamp will
be operated at a duty
cycle that is typically
50% or less. The result
is a significant reduction
in system energy use,
as compared to mercury
UV systems. This energy
reduction results because
lamp energy is not required
during the lamp OFF
period. For example,
the RC-801 and RC-802
systems typically use
only 150 watts during
the lamp OFF time. In
mercury lamp UV systems
the lamp must be ON
at all times due to
a long warm up period
prior to use.
RC-847
Model
RC-847 offers quick
setup and easy hands-on
operation in a lab or
inline process. It provides
everything you need
in an easy-to-use cabinet
that incorporates a
controller, high voltage
power supply and timer
unit with convenient
front-panel operator
controls. Also included
are circuit protection
and AC

power
distribution wiring
to run a full system
with lamp housings and
lamp blowers. The RC-847
may be configured with
high voltage power supply
options. The RC-847
is available with any
single-lamp or dual-lamp
housing configuration
as well as InterWeave™
operation.

TIMER
CONTROL MODULE
The
Timer Control Module
can be used to operate
a single lamp RC-801,
a two lamp RC-802 or
an RC-802 Interweave
system. This module
provides for two modes
of operation, Manual
and Timed. Manual mode
is used to turn the
lamp ON and OFF by simple
switch commands. The
Timed mode is used to
automatically toggle
the lamp ON and OFF.
In the Timed mode, the
lamp’s on-time can
be selected by the operator.
SWITCH
CONTROL MODULE
The
Switch Control box is
designed to provide
the operator with manual
control of a single
lamp RC-801, dual lamp
RC-802 or an RC-802
Interweave Pulse UV
Lamp
system.
ENVIRONMENTAL
and SAFETY FEATURES
The
high energy pulsed UV
light is environmentally
benign since it does
not create or use volatile
organic compounds (VOCs)
or create suspended
airborne particulates.
Xenon lamps do not generate
microwave RF radiation
or contain toxic
|
|
materials,
such as mercury, and
therefore do not expose
personnel to the potential
hazards due to mercury
lamp breakage.
LAMP
SPECTRA
The
Xenon lamp inherently
produces a broadband
spectrum suitable for
formulations that absorb
UV light from 180 nm
to 800 nm. Lamps are
available with up to
four different spectral
cut-offs, producing
unique wavelength properties
suitable for specific
types of curing challenges.
Effective lamp spectral
cut-off wavelengths
are listed below:
Type
A Lamp: 370 nm - Best
for visible light cures.
No ozone generated.
Type
B Lamp: 240 nm - Offers
optimum UV performance.
No ozone generated.
Type
C Lamp: 190 nm - Cuts
off deeper UV. Ozone
generated.
Type
D Lamp 160 nm - Allows
deep UV. Ozone generated.
Typical
spectrum for Type C
lamp
PHOTOINITIATOR
MATCH
To
achieve optimum UV curing,
the spectral output
of the pulsed UV lamp
must be matched to the
absorbance characteristics
of the photoinitiator
used in the adhesive,
ink or coating formulation.
This is due to the different
absorption characteristics
of photoinitiators and
the broadband radiation
characteristics of a
pulsed UV lamp source.

staff for assistance
