3.2.5.2 Overview of S-Feeder
Description: 9 different feeders are enough to process tapes with widths from 8 to 88 mm. The tape reels
on the feeder are taken up by the CO trolley tape container. The cutter then cuts up the empty tape
automatically. SIPLACE feeders are known for their short cycle times and highly accurate pickup
positions.
These feeders can also be used in other SIPLACE placement machines.
In addition to the tape feeders, bulkcase feeders, linear feeders, surftape feeders, Dipflux modules, CO
reject conveyors and manual trays can also be used. To protect the operators, unoccupied locations can
be equipped with so-called dummy modules.

3.2.6 Gantry
3.2.6.1 General
The placement machine is equipped with four gantries. These are used to accurately and independently
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.
Precise distance measuring systems determine the position of the X and Y axes. This involves the
optoelectronic 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 X and Y directions. This
prevents the typical frictional loss which occurs when complex drive systems 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.
