1.0 INTRODUCTION
DESCRIPTION
The DYNACH
EM® Model 300 Laminator
was designed to
be used with all LAMINAR®
Dry Film Photopolymers. Its primary func-
tion is
to apply LAMINAR resist from
a continuous web, using a process
of
heat and pressure, to substrate materials.
These substrate materials may be either
flexible or rigid, up
to 26 inches in total
width, between .005 thousandth of an inch
thick, up
to .250 inches thick and in
any length provided an adequate feed
mechanism is utilized. The maximum usable
resist width on the Model
300 is 24 inches.

A. GENERAL
B. MODEL 300 SPECIFICATIONS
1. The Model 300 LAMINATOR
is designed
for use with any
DRY FILM PHOTORESIST. The
Laminator is a new design
incorporating
significant im-
provements in dry
film lam-
inator technology.
2. The Model 300 uses heat and
pressure to laminate
DRY FILM
PHOTORESIST to flexible or
rigid materials up
to 26 inches
wide and 0.250 inches thick.
Maximum Photoresist film
width, 24 inches.
3. Materials typically laminated
with
DRY FILM PHOTORESIST
include copper-clad laminate
used in the manufacture of
printed circuit boards and
sheets
or rolls of metal for
chemical milling. Photoresist
can
be laminated to one or
both sides
of the working
material in a
single pass
through the laminator.
4. The Model 300 has two large
diameter, internally heated
Pressure Rolls with roll tem-
perature controlled by
two
solid state, three mode con-
trollers. This combination
of
temperature and pressure pro-
vides optimum dry film lam-
ination conditions. The heated
Pressure Rolls are in
intimate
contact with the Photoresist
for heat transfer to the Photo-
resist and the Printed Circuit
Board.
An Air Actuated Roll

WARRANTY
The Model 300 Laminator is warranted by Dynachem Corporation against
defects in material and workmanship for a period
of 90 days, from date
of receipt by the customer, during which time Dynachem will be res-
ponsible for the replacement or repair, at its option, of any defective
parts and for any labor charges connected with the repair of the laminator.
Dynachem, for an additional 90 day period, warrants that it will replace
or repair,
at its option, any part that proves to be defective; however,
the customer will
be responsible for all labor charges during this additional
90 day period.
Dynachem should
be notified in writing of any defect in material or
workmanship of the laminator and if so instructed by Dynachem, the
laminator or any part thereof, will be shipped, freight paid by Dynachem,
to Dynachem
for repair. Neither the laminator nor any part thereof
is to be returned to Dynachem without written authorization from Dynachem.
This warranty is effective only under the condition that Dynachem personnel
be present during the uncrating and installation of the laminator, and
should this not be the case, the warranty will be null and void.
Additionally, the warranty is null and void if the laminator is abused
or operated contrary to instructions or if alterations or repairs have been
made other than by a properly authorized Dynachem representative.
The warranty does not cover the rubber laminating rolls.

INSTALLATION
A. OPERATING SITE
1. Optimum Clearances: A work
table approximately 27" high by
24" x 48" is recommended
for mounting the Dynachem®
Model
300 Laminator. A three
foot clearance on all sides
is desirable.
2. Exhaust System: Since the
heated fumes from Dry Film
Photoresist are hazardous to
personnel, the Model 300
must be connected
to an
external exhaust system, pre-
ferably with a
3" diameter
flexible hose. The plant
exhaust system should expand
to a larger size if long runs
are required. A minimum of
100 cfm is required per 10
feet of duct work.
3. If the Model 300 Laminator
is purchased with the Model
310 Cleaning System the
Laminator is mounted on the
Cleaner base. In this com-
bination the Fume Exhaust
System from the Cleaner is a
4" duct into which the 3"
Laminator exhaust is con-
nected. In
this installation
the plant exhaust system
should use 4" ducting, and
have a minimum of 100 cfm.
B. INSTALLATION PROCEDURE
1. The Model 300 Laminator is
shipped completely assembled.
The Laminator has been
thoroughly tested at the fac-
tory prior
to shipping. How-
ever, because the Model'300
Laminator involves several
unique features, we
request·
that one of our representatives
be present at time of un-
crating and installation. This
will insure
that the warranty
will be in effect from the first
day
of operation. If damaged,
report promptly
to Dynachem
and file a claim with the
carrier. Remove all shipping
tiedowns. Place Laminator
on
work table. Adjust height of
each foot to share the weight
ofthe Laminator equally. Verify
Laminator is level.
2. Connect the Laminator to a
240 VAC, 60 or 50 HZ, single
phase electric supply line. Use
the "twist-lock" receptacle
supplied with the machine.
This matches the line plug
of the Laminator.
NOTE
If the plant receptacle does not
match the Laminator plug, replace
the plant receptacle with
that
provided.
3. Connect plant air system to
quick disconnect at rear of
machine and verify 40 psi
input pressure.
NOTE
Your Model
300 Laminator is also
set at factory to 32 to 34 psi roll
pressure. Do not increase beyond
40 psi or you will flex the rolls.
4. Connect the Laminator ex-
haust vent to the plant outside
exhaust system.
5. Check that the Pressure Roll
thermocouples make good
contact with the roll surfaces.
6. Verify that the Pressure Rolls
are securely installed and do
not shift from side to side.
If necessary
to tighten rolls,
see maintenance Section on
"pressure

speed until major wrinkles
are gone.
12. Dry Film Photoresist web ten-
sion is controlled by the Ten-
sion Control knobs
on the right
end
of each Supply Mandrel.
Proper tension is mandatory
to eliminate wrinkles in the
Photoresist. Too much ten-
sion can stretch and possibly
wrinkle. Too
little tension
can also allow the Photo-
resist
to wrinkle when lam-
inated
to the PC Board.
To
correct for Photoresist
wrinkling caused by too much
tension, turn the Tension Con-
trol Knob counterclockwise
until the web no longer
stretches. To correct for too
little tension, turn the knob
clockwise.
NOTE
Too much tension can result in
poor adhesion
of the Photoresist
at the edge of the Board. Proper
tension is the MINIMUM tension
which will avoid wrinkling
of the
photoresist on the laminated sur-
face
of the PC Board.
13. Verify the edges of the two
sheets of Dry Film Photoresist
remain aligned.
14. Replace the adjustable Feed
Table; adjust the Feed table

water.
NOTE
The buildup
of resist condensate is
minimized by using the proper op-
erating procedures recommended in
your photoresist data sheet from your
supplier, particularly operating
within
the correct temperature range.
3. Every week check the Photo-
resist Filter (located on the
12 1·83

right rear side of the Lam·
inator). If clogged with Resist,
replace the Filter. (Refer

8. Temperature Controllers-
Servicing
NOTE
Temperature Controllers are
pre-set at the factory and
should not require re-ad-
justment. Check Trouble-
shooting Section (following)
for problem analysis before
attempting to recalibrate
controllers.
(a) The Temperature Con-
troller's Triac, a solid
state
A.C. switch, con-
trols each cycle
of the
line voltage supply. The
unit can handle
10 amps
at
240 volts A.C. This
17 1-83

output circuitry deter-
mines the number of full
cycles that are directed to
the heater element. This
smooth proportional
power output accounts
for the very accurate
Temperature Control.
The Temperature Con-
troller is a three mode
controller having three
control functions:
Proportioning action;
automatic reset; and rate
action. The reset/rate ad-
justment is set at the Fac-
tory in the middle of the
range. For faster
processing, decrease the
time (clockwise) and for
slower processing in-
crease the time (counter-
clockwise). Shorter than
optimum time will cause
continuous oscillation of
the process. Longer than
optimum time will cause
the Pressure Roll Tem-
perature to take longer
than necessary to reach
the set pointtemperature.
(b) Recalibration of Tem-
perature Controllers.
NOTE
Before making any ad-
justment of the Tem-
perature Controllers be
certain that the Pressure
Roll Thermocouple
probe is making firm
contact with the Pressure
Roll and that the Ther-
mocouple leads are
secure. After operating
temperature
is reached,
Pressure Roll tem-
perature will oscillate
about the set-point (as
shown on the Deviation
Meter and the red LOAD
Light). Excessive oscilla-
tion can be corrected
with the Proportional
Band Adjustment (lower
front of face) as dis-
cussed below.
(c)
The proportional band is
the temperature band
around the set-point
through which the output
varies from full off to full
on. Thus, the Propor-
tional Band Adjustment
can be considered again
adjustment. At narrow
band,
the Temperature
Controller is most sen-
sitive. As the band is in-
creased, the Tem-
perature Controller's sen-
sitivity
is reduced, which
allows the Controller to
stop temperature oscilla-
tion.
(d) The best temperature
control accuracy will be
obtained with the Propor-
tional Band Adjustment
set to the narrowest posi-
tion which does not
cause temperature os-
cillation. When adjusting
the Proportional Band
Adjustment, use a small
screwdriver (blade width
3/32" maximum) and
turn the screw (right
screw) clockwise for
WI DE band width and
count.erclockwise for
NARROW band width.
Make adjustments in
small increments, allow-
ing time between each
correction for the
Pressure Roll tem-
perature to stabilize.
