5.25 Maximum of 50 characters for object names at the station
Object names (names of components, boards, placement lists, etc.) are restricted to 50 characters.
However, since it is possible to enter names longer than 50 characters in SIPLACE Pro, for
instance, such names are abbreviated during a download. This applies to SIPLACE Pro, SIPLACE
OIS, SIPLACE Explorer and the SIPLACE station software.
5.25.1 Restrictions
The maximum number of characters for a PCB barcode is still restricted to 40 characters for a
board.
5.26 "Long PCB" option
Long PCBs are boards which are longer than the processing area (PA) or processing conveyor, and
which must therefore be assembled in two passes.
A board of this type can now be processed in a number of steps within a single processing area.
This is done by first moving the board to the first stop position, clamping it and processing it. Once
processing is completed, it is transported on to the next stop position. Here, processing of the board
continues, i.e. the placement content of a processing area is no longer placed in a single pass.
Instead, the board moves to a stop position, position recognition is performed and the placement
content assigned to this stop position is placed. This sequence is repeated for all the specified stop
positions of the processing area. The processing areas of a machine with two processing areas are
independent of each other.
Irrespective of the machine type, N stop positions can be assigned to each processing area. The
placement content of a stop position corresponds to one step.

The following rules apply for the "Long PCB" option:
- If a global ink spot is defined, it must be possible to move to it in PA1, otherwise it is impossible
to decide whether to assemble the board or not.
- If position recognition is deactivated for subpanels and activated for the board, it must be
possible to move to the fiducials defined for the board in both processing areas.
- A subpanel can only be assembled in a processing area if it is possible to move to the
associated ink spot and the associated local fiducials, because
- it must be clear whether or not the subpanel is to be assembled before placement starts,
- the correction factors from the global position recognition must be known for placement.
All fiducials and ink spots for a subpanel must be located either completely in PA 1 or
completely in PA2.
- If placement of a component requires separate position correction, it must be possible to move
to all the fiducials defined for this placement position in the processing area in which the
component is to be placed.
- Fiducials can also be located outside the overlap region.
- Up to 6 fiducials must be defined for a fiducial set for a board.

-
The "Long PCB" option always applies to the entire line.
- The placement machines do not need to be switched off to start processing long boards.
However, the line must be emptied and the stations must be provided with new machine data.
- If the programming system is used to switch the conveyor mode while there is no board in the
conveyor, the new conveyor mode applies to the next board to move into the input conveyor.
- If there are boards in the conveyor during reconfiguration, these are moved through using the
old conveyor mode. The new conveyor mode only applies as of the next board to move into the
input conveyor. This can, however, only be moved into the processing conveyor when none of
the old boards are in the conveyor.
- There can be N stop positions in each processing area. When creating the job in the
programming system, a specification is made as to the stop positions in a processing area in
which the board is stopped and processed.
- The programming system is used to configure which of the stop positions can be used by the
optimization function. During optimization, the stop positions are determined and passed to the
station with the job specification.
- The "Long PCB" option also applies to machines with a dual conveyor.
- If the "Long PCB" option is set, ”Whispering down the Line” is automatically disabled.
5.26.1 Restrictions
- "Whispering down the Line" and "Whispering down the Machine" are only possible if only
identical stop positions (with identical offsets) are used in a line.
- It is not possible to check whether a stop unit (stopper, laser light barrier) is installed in the
incorrect position. No checks are made other than fiducial recognition.
- Ink spot recognition is not possible in "synchronous dual conveyor" mode.
- It is only possible to teach the PCB reference position for a conveyor lane if a standard stop
position is present (offset 0).
- It is not possible to buffer a board between the input conveyor and the output conveyor in "Long
PCB" conveyor mode.
- When manipulating fiducials, the operator is responsible for ensuring that it is possible to move
to the fiducial to be taught by selecting the correct gantry.
- The distribution of the fiducial positions and the placement positions across the processing
areas is not checked at the station. It is assumed that the data from the programming system
has been specified correctly in this respect.
