7.12.2 Implementing parallel placement
Lines with machines arranged in parallel take up a lot more space, so the parallel placement con-
cept was implemented with an underfloor conveyor and horizontal / vertical lift (HV shuttle). The
machines are still arranged in series, but the lift units and underfloor conveyors allow the line to
be operated in parallel. In this way, SIPLACE lines remain almost as compact as before.
Underfloor conveyor
Two conveyor belts carry empty or placed PCBs underneath the machines (see Fig. 7.12 - 1).
Horizontal/vertical lift (horizontal/vertical shuttle)
There is an HV shuttle at the start of a line, between the machines and at the end of the line. It
carries the PCBs between the underfloor and processing levels, and between the two tracks on
the underfloor conveyors.

7.12.3 Advantages of the productivity lift
The productivity lift can raise the productivity of a line overall because it increases the placement
rates of the machines on the line.

Fig. 7.12 - 3 Productivity lift – Avoiding stoppages
If lines are connected in parallel, individual machines may fail without bringing the entire line to a
standstill. It is also possible access individual machines while the rest of the line continues placing
without interruption.
This could be for
– process-related investigations or test operation
– programming PCB fiducials, package forms or test placements
– maintenance or repairs
– operating errors, such as not splicing tapes on in good time or missing components.
Another advantage is that the line can be reconfigured as required using the software, without
having to reset the machines.

7.13 PCB support
Item no. 00302454-xx
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 PCB supports on the lifting ta-
ble.
