Description
On SIPLACE S-25 HM the in-line
conveyor system guarantees a
quick adjustment to new PCB
widths. The change is made either
at the station computer using the
menu function or from the line
computer via the automatic width
adjustment unit.
Ceramic substrates can be also
transported and, if necessary, fas-
tened in place with the optional
ceramic substrate centering unit.
The conveyor can be ordered with
a fixed rail on right or left. As stan-
dard the SIPLACE placement sys-
tems are available with a single
conveyor system.

Description
Thanks to reduced non-productive
times the dual PCB conveyor can
substantially increase the through-
put, depending on the program. It
makes it possible to transport two
PCBs through the machine.
In the asynchronous mode of
transport a PCB is moved into the
machine in “slack time” while an-
other of the same PCB is being
populated. The non-productive
time caused by the PCB transport
is therefore completely eliminated.
The increase in placement speed
to be anticipated is between 10
and 30%, depending on the com-
ponents placed on the PCB.

Description
S-25 HM (Type 2) features a new
technique for conveyors. The PCB
is clamped from the bottom to the
top side of the conveyor. This of-
fers several advantages:
§ Higher real placement rate
§ Better PCB recognition (camera
focus point)
§ Shorter PCB change time
§ Easier change of fixed conveyor
edge right/left also in field
§ Quicker learning function, as the
PCB height does not effect the
Z-stroke
The conveyor can be ordered with
a fixed rail on right or left. As stan-
dard the SIPLACE placement sys-
tems are available with a single
conveyor system.
The dual conveyor has another
advantage: It is already prepared
for a retrofit to Flexible Dual
Conveyor mode, which allows the
handling of PCBs with a maximum
width of up to 380 mm. For this
feature SW 505 is required, which
will be available at the beginning
of 2004.
