The thermostat has a soft heat-up
functionthat prevents over-temperature
on the lamination rollers. After each
initial start the lower display will show
increasing temperature values until the
set value is reached.
Temperature setting proposals are
about105 °C for photoresistand 115 °C
for solder mask. You must determine
the best setting for your application. If
the temperature is too low the resist will
not stick to the copper, if it is too hotthe
material developsvapoursthat could ir-
ritate your nose and throat, and the re-
sist could loose its sensitivity to light or
could be otherwise damaged.
The speed setting depends on the tem-
perature conductivity of the material
you want to laminate. As a starting va-
lue for your own test we recommend a
setting of 0.5 on the potentiometer sca-
le. A too fast or too low speed can show
the same faults like a too low or a too
high temperature setting.
The knobat the right side of the lamina-
tor serves for turning the lamination
rollers by hand. This is necessary be-
cause one important principal of con-
struction of the RLM laminators is that
the transport rollers are separate from
the lamination rollers. So the knob ser-
ves mainly for feeding the laminate un-
til the transport rollers can grab it. You
will need this knobonly once each time
you mounta new coil.
The knob on the lower right front is
used to adjust the lamination pressure.
This is important as the RLM lamina-
tors can be used for solder mask appli-
cation as well. A scale to read out the
setting can be found on the outer right
side of the unit, beneath the hand knob.
In order to well press the mask into the
profile between the copper traces, we
recommend a setting of 4 to 5. Photore-
sist application is done at a setting of 1
to 2.
3. Mounting the laminate coils.
The following procedure is the same
for photoresist and for solder mask la-
minate, but we assume you use only
one of both types at a time on both the
upper and lower coil.
Unpack the laminate rolls from their
safelight boxes and mount them on the
left flanges of the coil holders. See the
threading diagram in appendix 1 of this
manual in order to have the right sense
of coil rotation. Mount the right flanges
and push them onto the coil as far as
possible. The coils must not slip on the
flanges. Mount the coil holders back to
the laminator and put the take-uprollers
in place.
The laminate consists of three layers.
These are the outer, strong and transpa-
rent polyester cover foil, the soft and
sticky laminate layer itself and a thin,
soft and mat plastic foil on the ‘‘inner’’
side of the compound. This thin foil
prevents that the laminate sticks to itself
when it is on the coil, butmust be remo-
