1.2 Regular use of the RSS-110-S system
This RSS-110-S (reflow solder system) is specified for use in laboratories or industrial
facilities use only. For any other use as mentioned in this operation instructions,
UniTemp GmbH does not assume any liability and any warranty claim will expire.
The equipment is NOT to be used for:
any usage which are not defined above, especially the processing of parts,
equipment or gases for which this manual is not foreseen.
the connection of any units or equipment which have electrically active parts.
1.3 Description of functions of RSS-110-S system
The process atmosphere is defined by using process gases or vacuum. Delivery, instal-
lation and commissioning are very comfortable to handle. The complete system is very
small and requires only a minimum of space.
The inner walls of process chamber (both on fixed bottom and on hinged cover) are wa-
ter-cooled. The process chamber can be evacuated by vacuum pumps (roughing pump,
e.g. membrane pump or rotary vane pump).
The heating plate inside of process chamber is „hardcoated“ and therefore extremely
stable and scratch-proof. The samples are placed on this heating plate. During cooling
process the heating plate is pneumatically pushed down and brought in contact with
permanently cooled chassis. No pieces may be dropped between heating plate and
chamber because cooling down process could be disturbed permanently and the
heating plate could be damaged.
The marginal thermal mass of the reflow solder system, the heating and the cooling
system allow a controlled heating-up of the samples up to 120 K/min and a cooling
down rate up to 150 K/min (depends on model). An integrated type-K thermocouple
allows accurate temperature measurement. The process control enables the application
of any inert process gas.
Check of the soldering chamber atmosphere
A gas distribution system permits an evenly controlled atmosphere in the process
chamber. The present system is equipped with one process gas line controlled by mass
flow controller enabling a maximum flow of nitrogen (N2) gas of 2 standard liters per
minute (Nlm).
Operation of reflow solder system
Programming and operation of this reflow solder system is done using the touch panel
(Simatic TP700). The touch panel allows storage of 50 programs of up to 50 steps each.
Process data can be stored onto USB 2.0 memory stick or to computer network
(requires integration into network domain). Operation of touch panel is explained in a
separate operation instructions.

Operation Instructions RSS-110-S En Ver. 06.2016 Page 8 of 13
The reflow solder system RSS-110-S is designed as table top machine and therefore
has got very compact dimensions:
Width: 274 mm
Depth: 517 mm
Height: 215 mm
Weight: 14 kg
A stable laboratory table (working height approximately 70 cm) with a minimum floor
space of 40 cm x 60 cm (W x D) is recommended. For service purposes it is required to
have rear side accessible to disconnect peripherals from or connect peripherals to RSS-
110-S reflow solder system.
Both the recirculating chiller WC I (available as option) or the optionally available vacu-
um pump can be placed in another room (noise emission). They can be remotely con-
trolled by the RSS-110-S reflow solder system however you have to take care that both
units are switched on before switching on the reflow solder system.
2.1 Power connection
2.1.1 Power supply of reflow solder system
The reflow solder system RSS-110-S is operated with 230 V, 50 Hz. For connection to a
power socket with 10A maximum current (circuit breaker with slow characteristic) the
provided 230V power supply cable with blue Neutrik connector (2 m length) has to be
used (see no. 12 in Figure 3).
2.1.2 Power supply of chiller and vacuum pump
The reflow solder system RSS-110-S provides 230V electric output for the vacuum
pump (see no. 13 in Figure 3) and 24V switching output for chiller (see no. 15 in Figure
3).
A chiller type WC I ordered through UniTemp is already equipped with an internal
switchbox (24V switching relay). Any other chiller model can be operated on the RSS-
110-S reflow solder system by using an external switchbox (option RSS-SW).
The external switchbox should be placed
near to the chiller. The remote cable (24V)
features a length of 2 m and has to be
connected to both the remote outlet
connector of reflow solder system (see no. 15
in Figure 3) and the remote inlet connector of
external switchbox (see no. 16 in Figure 5).

Operation Instructions RSS-110-S En Ver. 06.2016 Page 9 of 13
The power supply socket (see no.
17 in Figure 5) has to be
connected to local single phase
power supply socket (100…230V).
The chiller has to be connected to
chiller power supply socket (see
no. 18 in Figure 5).
The status LED shows a green
light when the chiller is switched on
by reflow solder system.
2.2 Cooling water connection
The cooling water connections are placed at the rear side of the system. The cooling
water inlet is done using plastic tube with outer Ø 8 mm (8 x 6 x 1) (see no. 10 in Figure
2), the cooling water outlet using plastic tube with outer 10 mm (10 x 7.5 x 1.25) (see no.
9 in Figure 2).
Maximum inlet pressure: 5 bar
ΔP Input - Output: 4 bar
Water temperature: between 16 and 20 °C
Only decalcified water should be used. Optionally we offer a closed loop water cooling
system; the cooling water will be enriched with a commercial available standard cooling
water addition. For a limited period an operation with mains water is admissible.
Important - Attention:
Connection to tap water is at your own risk; there is no warranty for clogged cooling
channels.
2.3 Connection of process gas and CDA
The RSS-110-S reflow solder system features two different types of gas inlet
connections (see Figure 2 and Figure 3):
i) Process gas inlet: there is one inlet (PU tube with outer diameter 4 mm)
located at rear side of chassis (see no. 14 in Figure 3). The maximum flow of
nitrogen (N2) gas is 2 norm liter per minute. A pressure of 2…3 bar (0.2…0.3
MPa) is required.
ii) CDA (compressed dry air): there is one inlet (PU tube with outer diameter 6
mm) located at left bottom side of connector block. Compressed dry air
(cleaned, dry and oil-free compressed air) is required to drive the heating
plate (pneumatic operation) and the vacuum valve (if vacuum option is
ordered). As alternative inert gas (e.g. nitrogen gas) can be used. A pressure
of 3.5…4 bar (0.35…0.4 MPa) is required.

2.4 Storage of process data
The RSS-110-S reflow solder system can store process data on a USB 2.0 memory
stick. The stick has to be put in the USB 2.0 socket on right side of touch panel (see
Figure 1). For network integration of RSS-110-S reflow solder system it has to be con-
nected to a computer network using the network socket (at bottom side of touchpanel
module) and being integrated into a computer domain. Please consult the IT administra-
tor!
The USB 2.0 memory stick also allows the storage of exported programs from touch
panel and later import back to touch panel.
2.5 VNC Server
A license free VNC server is installed on the RSS-110-S system. Connecting the RSS-
110-S to a computer network or to a PC allows remotely controlling the system through
TCP/IP protocol by using a VNC client. The IP address of touch panel is 192.168.178.90
(this IP address must not be changed!), the password for VNC sessions is “admin”.
2.6 Exhaust
The ventilation outlet (DN16) is located at the rear side of connector block (see no. 8 in
Figure 2). If possible operate with the system beneath an exhaust (e.g. flow-box) or
connect the ventilation outlet directly with ventilation, so that steam formation during the
processes will not cause smells.
2.7 Vacuum pump installation
In case vacuum option is ordered, the pneumatically operated vacuum valve (with DN
16 KF flange) is already connected to the rear side of RSS-110-S reflow solder system.
The flexible metal hose (provided with the delivery) has to connect the vacuum pump
with the RSS-110-S system.
The vacuum pump (Ilmvac MP 601 Tp) has to be electrically connected to the connector
at the rear side of RSS-110-S system.
3 Location of switch on/off button
On the rear side of RSS-110-S reflow solder system the button for switching ON and
OFF the system is located. Before switching on make sure that all previous items of this
chapter have been effected and the devices are thus correctly connected. Vacuum
pump and water cooling have to be switched on. Make sure that soldering chamber and
hot plate are freed and clean.

4. Operation and control functions
4.1 First switch-on and stand-by modus
After switching on the RSS-110-
S reflow solder system (push
button ON), the internal touch
panel boots the process control
software (SPS_Soft).
4.2 Opening and closing of the hinged cover
In order to open the hinged cover the handle has to be pulled to release the door latch.
Then the handle has to be moved up until the hinged cover reaches its rest position.
In order to close the hinged cover, firmly grab the handle and carefully move down the
hinged cover. With the cover being fully down lock the door latch by pushing the handle
to its most rear position.
Be careful when loading the process chamber. We recommend wearing gloves
when loading samples on the heating plate. Put your objects slowly and smoothly
onto the heating plate.
WARNING:
Please be aware that the handle is not locked by any locking mechanism! There-
fore be careful to not touch any hot surface inside the process chamber!
The touch panel always indicates the temperature of the heating plate.
THERE IS A SEVERE DANGER OF HOT SURFACES!
Some hints:
We recommend to keep the top part closed. If should be opened and closed for
loading and unloading parts only (risk of particles).
Let programs run from start to finish! Abort programs only if absolutely necessary!
