Preface
The RMP 210 multilayerpress was designed
for use in PCB labs. It allows uick
prototyping of multilayer PCBs of 4 or more
layers according to industry standards. A
compact and floor standing aluminium rack
contains the pressure supply and heated
press plates, covered by a big door with
security switch.
The unit is controlled by two digital
thermostats, one digital timer and a
pressure valve with meter. Two strong air
ventilators are activated automatically
during cooling cycle.
To produce a multilayer with this machine
you have to go through the following steps:
•Fixing and inserting the prepreg batch
•Building up pressure
•Turning on the heater
•Heat up cycle
•Press cycle at set temperature
•cool down cycle
Taking out the multilayer
The whole process lasts about 3 hours.
When you insert a batch of 250 x 350 mm,
you get a usuable multilayer size of approx.
210 x 300mm, depending on the uality of
the pcb material you are using (losses in
size due to resin flow inside of the stack).
Safety Regulations
This Multilayerpress is designed for use in
laboratories and shall be operated by skilled
staff.
The general safety rules for operating elec-
trical machines need to be applied.
Before all maintenance work disconnect the
machine from power supply.
Children and pets need to be kept away.
The installation location of the machine is of
special importance. You should choose a
mostly dust free room with a non corrosive
atmosphere.
There is a door security switch that will de-
activate the pressure bottom when door is
opened during operation. THAT MAY DES-
TROY YOUR MULTILAYER but it is an im-
portant security feature of the machine.

NOTE: while compressor is running, it is
not allowed to switch off the machine or
open the door of the press-room.
If because of
power failure,
compressor
should be
switched off
while running,
open the rear
bottom door (1
and reset the
compressor. Dis-
charge the com-
pressed air (2
and reset the mo-
tor safety switch
(3 . Without that
procedure, there
is a risk of over-
loading the com-
pressor motor which
may lead to severe
damage.
When you turn on the
main switch, the com-
pressor will start for
about one minute. Take
care that there is noth-
ing between the upper
and the lower press
plate, that could damage the machine or
even burst and blow out of the machine.
Use only appropriate material to avoid fire
and resulting severe economic losses.
Apply suitable temperatures and pressures
to avoid burning of the pcb material and
development of poisonous or harmful gas.
Cool down machine to a maximum of 50°C
(takes about 30-45 min.) to avoid severe
burnings to the skin. Or wear suitable pro-
tective gloves.

cognize any damage after unpacking you
need to declare this transport damage to
the shipping agent immediately in written
and verbal. In this case please also notify
us.
To unpack, remove the cardboard cover
and the lateral carton / wood package. On
the pallet you will then see a piece of wood
with screws. Remove this piece to get the
wheels free that the machine is sitting on.
Due to the weight and to avoid tilting the
machine do not just roll the unit off the pal-
let. Use a fork lift and the assistance of
skilled staff to take the unit off the pallet
and place it on even ground. From then on
the machine may be moved on its rollers.
Operating
There is a red mains (and emergency stop)
button on the right front. Push this button in
case of emergency and to cut the machine
of the main supply. Start the machine by
pressing that red button.
This will activate the compressor.
The machine is e uipped with special high
pressure compressor. You get access to
the compressor when you open the back
door underneath the fans.
Make sure to pull off the
plug before opening this
door (Mortal danger be-
cause of electrical
stroke).
Take care that there is
nothing between the up-
per and the lower press
plate, that could dam-
age the machine or
even burst and blow out of the machine.
Pressure adjustment
Whenever the PRES-
SURE switch is activ-
ated, machine will close
the press plates. As that
re uires compressed
air, the compressor will
start running again (for
about 2 minutes de-
pending on the pressure
preset).
ATTENTION:
Never switch off ma-
chine or open the front
door (safety door
switch). If this happens,
for example in case of a
power failure, you need
to reset the compressor.
To do so read on
chapter 2 safety regula-
tions.
Pressure adjustment is
done with the turning
valve in the front panel
underneath the mano-
meter read out.

For the correct pressure adjustment please
read the instructions of your pcb board sup-
plier. As a thumb rule you can set a pressure
of 12 bares = 12 tons for a board of 250 x
350 mm.
Timer
The timer is controlling the heat-up/cool
down se uence of RMP 210. The preset
time is the total heating time. After that, the
cooling ventilation is started and the heat-
ers are switched off while pressure is still
adjusted.
To reset the timer to zero press all three
buttons at
once.
The Button
PROG (far
left) is used to
select the digit
to be adjusted.
Press it once
to change
hours. Press
again to
change
minutes. Press
again to
change seconds and once again to come
back to timer mode. Note: timer setting can
not be varied while timer is controlling a
press cycle.
The button + is to increase the value of the
blinking digit.
The button - is to decrease the value of
the blinking digit
The button Reset is used to reset the time
to adjusted time.
The timer has a auto-reset function at the
end of the count-down.
The button Start/Stop starts or stops the
timer.
System Reset: to cancel the adjusted
process time, press all three bottoms for a
second. Count-down time is now at zero.
To reset timer completely, press all three
bottoms.
Heater Adjustment
The upper and lower
pressure plates have
separate heater adjust-
ment facilities. Once
the timer has started,
the thermostats will
turn on. Both heaters
are preset to 175°C
(which is standard for
most application). On
re uest heater adjustment up to 300°C is
possible. Both thermostats will operate with
6 °C/min heat-up speed. This standard set-
ting can be adjusted upon re uest.
The thermostat has two displays and four
buttons. The upper display shows the actual
temperature, the lower one shows the set
value. Press the mode button once and use
the up and down arrow keys to set the de-
sired temperature, in this picture 155°C. Fi-
nally press the mode button again. This will
save the value. The
out/off button serves to
turn the heaters off and
on manually, but is not
used in normal opera-
tion. The OUT LED
right to the upper dis-
play shows if the heat-
ers are actually on or
off.

The thermostat has a soft heat-up function
that prevents over-temperature. After each
initial start the lower display will show in-
creasing temperature values until the set
value is reached. Temperature setting pro-
posals are about 175 °C for normal and
fresh prepregs. You must determine the
best setting for your application. If the tem-
perature is too low or heating time too
short, the laminate will have delamination
problems or air-bubbles inside. Both will
damage the multilayer board.
Work Flow:
Operation details are related to prepregs
and inner layers specifications. As a matter
of fact, these settings may change depend-
ing on the type of prepregs.
a) If you do not prefer to swim press (this is
possible for 3- 4 layer board) fix your lay-
ers with reference pins or rivets. We re-
commend to have the reference pins out-
side of the press plates and to include
the reference marks in your film layouts
for all layers
b) protect your press plates with tedlar foil
or something alike to prevent the press
plates from sticking to your pcb. Select
suitable material to avoid fire and result-
ing severe economic losses.
c) Insert PCB stack into press plates
d) Select appropriate temperature and pres-
sure to avoid burning your pcb and emer-
ging of poisonous gas.
e) pressure is adjusted according to board
specification. For boards 210 x 300mm²:
approx. 12 bar
f) heater temperature is selected (accord-
ing to condition and type of prepregs nor-
mal range: 155 - 175°C)
g) heater is activated
h) heating-up procedure and press se-
uence at preset temperature (normally
60-120 minutes. Time depending on tem-
perature preset and on room temperat-
ure according to condition / type of
prepregs)
i) cooling down under pressure to 50° C or
lower (about 30 -45min) to avoid skin
burns. If you want to take out stack at a
higher temperature wear suitable protect-
ive gloves.
j) Never take out stack at a temperature
higher than 100°C. Danger of delamina-
tion.
k) PCB stack is taken out of the machine.
l) boards are depinned.
The se uence will take all at all approx. 3
hours. Gross size of the PCB is 250 x 350
mm which will result in PCB net size of 210
x 300 mm². Depending on the material you
use, the rim of your multilayer will show less
resin as in the middle and needs to be cut
off (normally 1-2 cm on each side. In the
meantime board supplier improved their
products so this effect may not occur at all)
Process time will decrease down to half an
hour if you take out stack at a temperature
of about 100°C. But this is made on the op-
erators responsibility and we will deny any
liability for this.

You can press up to 4 Layers in floatin technique. Add reference holes into your inner layers and adjust
your layouts accordin to these holes.
Reference holes can be inserted into your layout with the help of IsoCam and can be drilled with the
Bun ard CCD.
Cut your prepre s and your outer layers smaller (as seen in the upper picture), so the resin of the boards
will not flow into the reference holes durin the press cycle. You will need these reference holes later on to
re ister your pcb a ain for drillin on the CCD.
If your pcb is smaller than the press area of the machine (250 x 350 mm), we recommend to adapt the
pressure accordin to this formula:
PA = (PW x AW) / AA
PA = desired pressure for your pcb in bar
PW = machine pressure RMP 210) in bar
AW = press area of machine (250 x 350 mm = 8.75 dm² = constant)
AA = press area of your pcb in dm²
Example:
If you want to press a pcb with 120 x 120 mm with a pressure of 16 bar, please adjust formula:
(PA x AA) / AW= PW
(16 bar x 1,44 dm²) / 8.75 dm² = 2,63 bar
Set this pressure at the machine. For small pcbs we enerally recommend to panelize the pcb and so in-
crease the press area.

If you want to press more than 4 layers, it is necessary to fix all layers with reference pins to prevent the
layers from movin durin the press cycle.
A ain you can add reference holes into your pcb with IsoCam and drill them with the Bun ard CCD.
Reference rivets D3.0 x 5.4 mm can be obtained from Bun ards in packa es of 100 rivets.
These rivets have to be mounted outside of the press area as in the upper picture, so they can be eas-
ily removed after pressin .
See picture 3 for a sectional view on a press stack. The press sheets protect the press plates from
mechanical dama e and the separation foil protects both press sheet and press plate from contamina-
tion with resin
