6.20.1 Concept of parallel placement
Placement lines are generally arranged in series and are linked to one another serially. The
placement program is processed sequentially while the PCBs are transported from one machine
to the next. This means that the placement of a PCB is distributed between various machines.
When machines are connected in parallel, the components to be placed by individual machines
are combined. Several machines work through the same placement program. They place all the
components on one machine that would be distributed between several machines with serial pro-
cessing. When one machine runs out of capacity, the PCBs are moved to and placed at the next
machine with the same placement program. This combination of machines with the same compo-
nents to be placed is known as a group or “cluster”.
6.20.2 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.

6.20.2.1 Underfloor conveyor
Two conveyor belts carry empty or placed PCBs underneath the machines (see Fig. 6.20 - 1). The
maximum component height is 17 mm.
6.20.2.2 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.

6.20.3 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.

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
