2.2.2 Pneumatic unit
The pneumatic unit is mounted on a compact rack unit and located on the right side of the middle
section. A lockable door, which can be opened with the machine key, prevents access to the unit.
The pneumatic unit contains all electrical connections for the compressed air and transport control
systems. The transport control system with the SMEMA (Siemens) board interface facilitates the
transport of PCBs within the machine and to the previous/next stations.

2.2.2.1 Pneumatic Circuit for Cooling the Y - Linear Motor for Placement Area 1/2
An additional pneumatic system, supplied by ambient air, has been developed to cool the Y-mo-
tors. The ambient air is sucked in over a filter with the aid of a fan motor and supplied to the Y-
motors. The compressed air then escapes at the side of the Y-motor.
2.2.2.2 Pneumatic Circuit for Cooling the X - Linear Motor for Placement Area 1/2
The X-motors are cooled with exhaust air from the vacuum generator of the C&P head or twin
head.
2.2.2.3 Compressed Air Distributor Block
The pneumatic unit is used to prepare and distribute the compressed air required in the machine.
The pressure in the compressed air connection have to 5.0 bar.
The following pneumatic circuits are supported via the compressed air distributor block:
Gantries 1-4 (placement heads), vacuum generation: 5.0 bar
Transport system: 5.0 bar
Tape cutter for the locations 1-4: 5.0 bar
Nozzle changer for the locations 1-4: 5.0 bar
Docking units for the component changeover table: 5.0 bar
Bulkase feeder on the location 1-4: 2.5 bar
The fine adjustment of the individual pneumatic circuits is performed via throttle valves at the
pneumatic units.
WARNING: Tthe nozzle changer for the C&P20 head is operated with 4.5 bar, in contrast to the
nozzle changers for C&P6/12 heads, which use 2.5 bar.
