The LC6 now comes loaded with 3 major new functions for better stabilized optical curing

WORLD-WIDE

OPERATION

Memory Step

for 9 types 7-step programs

Stable operating mode available

Program the irradiation intensity and irradiation time to any level you want! Free-
ly set the UV irradiation conditions to match the component you want to bond.
The LIGHTNINGCURE LC6 lets you store nine types of 7-step programs in the
memory, so optimal irradiation conditions matching the component for bonding
can be set just by changing the program number. This holds true even when
multiple bonding components are flowing in the same production process or
when shifting to different production lines.
The LC6 is especially ideal for components that must be fixed in place with
high precision. The mounting positions of these components often deviate due
to stress warping and contraction in the adhesive that causes positional shifts.
Using the LC6 gives better production stability and higher product yield espe-
cially for components demanding high position precision.

Optical power monitor with optical feedback

(option: sold separately)

You can now select stable operating modes to re-
duce variations in light output over elapsed time
while also lowering power consumption about 10
percent compared to standard operation.
Variations in light output can be reduced about 15
percent over 3,000 hours. This means you get stable
light output all the way to the final lamp life stage.
This operating switch is on the surface of rear panel.

An optical power monitor with optical feedback can be added as a
useful option for maintaining constant irradiation power. The built-in
sensor constantly monitors the light intensity that usually varies with
operating time, and the sensor output is feedback to control the iris
so the light intensity is always maintained at a preset constant level.
The irradiation power (reference value) when using the standard
light guide is shown in a digital display (in watts) on an LCD panel.
This eliminates mistakes that occur due to using the wrong condi-
tions or human errors during measurement.
This also means finer control on fully automated lines.

FEATURES & FUNCTIONS

Clever layout allows a compact body

The smallest size (volume) in its product class* compared to previ-
ous products including those made by other manufacturers. Weight
has been also reduced 6.5 kg making it 1.5 kg lighter than previous
other models. Superior product features have all been condensed
into this new, compact body.

*For light sources using lamps rated at 200 W or more.

Anybody can use it! One-touch replacement!

Lamp is replaceable in less than 30 seconds!
Just insert the lamp to replace it. No wiring to worry about. This is
so easy you can do it with one hand.
Lamp is the cassette type with a preset optical axis so no trouble-
some optical alignment is needed after replacement.

* The L8388 and L8878 are exclusively for previous cassette type lamps.

These are replaced the same way as our previous lamp models.

Light intensity adjustable anywhere within 0 to 100%!

Selectable positions of light guide port

Full line-up of external control equipment

(D-sub connector: standard feature, terminal block: option [sold separately])

Power supply compatible

in world-wide

An electric diaphragm mechanism allows a digital display of the rel-
ative light output from 0 to 100% on the LCD panel. Unlike conven-
tional analog scales, this means highly precise light irradiation. Light
output also can be controlled from an external device, so meeting
various kinds of measurement conditions is now even easier.

A front port type and a rear port type are available. The front port
type allows lamp replacement from the operation panel side. This
helps hold limits on equipment movement and installation location
to a minimum.
Select the light guide port position that best matches the compo-
nent for bonding and its mounting position.

Left: Front light guide port type, Right: Rear light guide port type

Internal power supply automatically switches to a 100 or 200 V input.
There is no problem when shifting the operating location in world-
wide.

Turning the lamp on and off and open-
ing-closing of the shutter can be control-
led by input of external signals. An alarm
signal output is also provided. This
means ideal usage conditions on semi or
fully automated production lines.

Restores operation in about 10 seconds after power outages of a
second or less.
Conventional products take at least a few minutes to start up again
after a power shutdown, so you can see this function drastically
shrinks down-time due to power outages.
This function is especially convenient in places where the supply of
power is intermittent or unstable.

Our 200 W lamps have high intensity equal to lamps in the 250 W
class. Light sources using our 200 W lamps also have less power
consumption than those using 250 W lamps.
Power consumption is the lowest in its class (within 300 VA). This
means using multiple UV light source units at production facilities
will yield tremendous energy saving benefits.

GUV intensity distribution

GStructural View

The LC5 yields an extremely strong spectral distribution in the UV
range most effective for UV curing. UV intensity distribution is de-
pendent on the distance from the light guide output end to the target
surface to be irradiated, as well as on the type of light guide used.
The greater the distance from the light guide output end to the tar-
get surface, the more the maximum UV intensity drops and the
more the light beam expands (see below).

UV intensity generally declines with lamp operating time. Hamamatsu
has drastically improved these drops in light intensity by using a
mercury-xenon lamp whose electrodes suffer almost no wear and
an improved optical system.

Highly durable shutter

The stepping motor used for the shutter in the LC5 has a service
life 5 times longer than conventional rotary solenoids. Along with
eliminating shutter troubles, the once noisy sound of shutter open-
ing and closing can now hardly be heard. This makes the LC5 ideal
for 24-hour continuous operation.

No optical axis alignment

Uses a highly stable mercury-xenon lamp* developed expressly for
analysis and measurement applications. There is almost no wear
on the electrodes and no positional shift of the arc point.
Absolutely no optical axis alignment is needed, even during lamp
replacement or during lamp use.

GElectrode wear

Before use

After 2000 hours of use

The LC5 combines a mercury-xenon lamp having high-intensity
UV line spectra with an elliptical reflector (UV cold mirror) having
reflectivity higher than 90% in the UV range and a quartz light
guide with excellent UV transmittance.
The lamp can be operated in a horizontal position, so the optical
system has less light loss compared to lamps operated in an up-
right position, allowing the UV light to input efficiently to the light
guide. The elliptical reflector efficiently reflects only the UV light,
and lets heat rays and visible light pass through to prevent adverse
effects from heat on the irradiated point.

High efficiency optical system - no heat problems

Selectable wavelength

The LC5 allows you to select the wavelength range you need. The
"-01" type suitable for wavelengths around 365 nm and the "-02"
type enhanced for 250 nm band are provided. Select the light source
that matches the adhesive agent you use.
These can also be combined with UV-transmitting filters that cut visible
and infrared light, and minimize heat effects on the irradiated point.
A visible light type is also available (radiant wavelength range from
400 nm to 700 nm).

FUNCTIONS

CONTROL

WARNING

WARRANTY PERIOD

G Light

This equipment emits very strong ultraviolet light which is harmful to eyes and the skin.

Also, as the light emanating from the light guide connection aperture contains infrared light in addition to ultraviolet light,

its irradiation will cause heat generation.

Be sure to observe following instructions for operation of the equipment.

� Never look directly into the light guide connection aperture or at the light emanating from the light guide. Strong ultravio-

let light can cause visual disorder.

� Do not allow light to come into contact with skin. Contact with skin may cause sunburn-grade inflammation. Always

wear safety glasses, gloves, and other appropriate protective gear when operating this equipment.

� Never allow light from the light guide to radiate onto flammable material.

� The unit includes an interlock that prevents the lamp from lighting while to top cover is open. Never attempt to override

the interlock function by manually depressing the switch, as this may result in uncontrolled release of dangerous ultra-

violet light.

G High-Voltage trigger

� The mercury-xenon lamp employed started by a high-voltage (30 kV) pulse applied at the lamp electrodes.

As protection against accidental electrical shock hazard, the design includes an interlock switch that disables lamp op-

eration while the top cover is open.

Never attempt to turn on the lamp by blocking the sensor window of the interlock switch.

G Lamp Replacement

� The inside of the lamp housing becomes extremely hot during lamp operation.

Before replacing the lamp, switch it off and run the cooling fan for at least 15 minutes.

� Always exercise due caution when handling or replacing a lamp.

A lamp contains high-pressure gas [approximately 1 MPa (10 atmospheres) at room temperature, approximately 4 MPa

(40 atmospheres) during operation] and may burst if dropped or otherwise impacted.

G Inhibition of Removal and Modification

� Do not remove the top cover or under cover unless absolutely necessary and never touch any of the screws inside the

unit. As the internal components of this unit have been precisely adjusted, disassembling or modifying the equipment

can cause problems with the unit, fire and electrical shock.

This device is guaranteed for one year after delivery date from us. The warranty extends only to replacement of the prod-

ucts. The warranty does not cover damage due to misuse or natural calamity.
