The PCB is transported into the placement area until the laser light barrier triggers the stop signal
for the PCB conveyor. The lifting table with the PCB stops then moves up into a position in which
the PCB is not yet clamped and can still be moved by the conveyor belts. The two PCB stops are
level with the PCB, and the PCB supports (magnetic pins) are already in contact with the PCB.
The two conveyor belts move the PCB against the PCB stops and align them at the same time.
The lifting table then moves into its top end position, clamps the PCB and releases it from the PCB
stops so as not to affect the placement process. After the placement process, the lifting table and
PCB alignment are lowered and the PCB is moved on.

6.12 Siemens interface
Item no. 00116808-xx SIPLACE interface HF/X/D3
The conveyor interface on the placement machines from the X-series is configured to the SMEMA
standard. It is, however, still possible to use this interface in accordance with the Siemens stan-
dard. This is a significant benefit when an X-series machine is to be integrated into older SIPLACE
lines, in which case it would not be necessary to retrofit the older machines to conform to the
SMEMA standard.
Simply configure the conveyor interface of the X-series machines to the Siemens standard and
connect the machines using the associated interface cable.
More detailed information can be found in the Siemens conveyor interface retrofit instructions",

Item no. 00119680-xx Magnetic pin support HS/HF/X/D-series
Wide boards tend to deflect during placement such that, under certain circumstances, the compo-
nents can no longer be placed with the desired accuracy. Highly curved PCBs also affect the
placement accuracy. This problem can be easily rectified by fitting magnetic pin supports on the
lifting table.

6.14.1 Safety instructions for the vacuum pump
WARNING 6
The vacuum pump should have a separate fuse.
When connecting the vacuum pump, make sure that a ground wire is connected in addition
to the standard main power cable. A suitable grounding rail should therefore be provided in
the customer's network.
Pay particular attention to the safety instructions in the operating instructions provided.
6.14.2 Description
Every Collect&Place head has a separate vacuum generator that supplies the holding and place-
ment circuit with the vacuum that it needs. The vacuum generators for the placement heads work
on the Venturi principle. When combined with a vacuum pump, the compressed air consumption
can be greatly reduced on the SpeedStar (C&P20). The ongoing operating costs will fall in line
with the energy costs.
