3.4.4 Pneumatic Unit
Pneumatic Unit
The pneumatic unit is a fixed installation inside the machine and is located to the right of the middle sec-
tion of the machine, behind a flap. The pneumatic unit includes all electrical connections for control/reg-
ulation of the compressed air supply.

The D1D1i//D2/D2i pneumatic unit is mounted on a com-
pact rack module and is located in the right-hand, middle
section of the machine. The unit is secured by a lockable
door and contains the complete compressed air supply.
In D3 machines, this unit also contains the SMEMA inter-
face (Siemens) to the upstream and downstream sta-
tions.

General
Precise distance measuring systems determine the position of the X and Y axes. This involves the op-
toelectronic detection of marker lines on the incremental scales and the transmission of the track signals
to the axis control point in the control unit.
Direct drive techniques are then used to position the placement heads in the Y direction (in the X direc-
tion also for D3 machines). This prevents the typical frictional loss which occurs when complex drive sys-
tems are used. This solution also avoids the wear and tear which can significantly impair the accuracy
of positioning systems over time.
X-axis drive
With the help of a toothed belt, the rotary movement of the X-axis motor is directly converted into a
lengthwise movement of the placement head, in the X-direction.
Y-axis drive
A linear motor moves the placement head lengthwise, in the Y direction.

The D4/D4i placement machine is equipped with four
gantries. These are used to accurately and independent-
ly position the four C&P heads in the X and Y directions.
Due to their construction, the gantries are resistant to
buckling. The precise mechanical guidance of the axes is
achieved with the aid of ball bearing units.
