3.2.10 Miscellaneous
3.2.10.1 C:\temp directory does not exist
■ Description: If the ‘C:\temp’ directory doesn’t exist, the following error
occurs: ‘Optimizer Error: 1001: Error created directory C:\TEMP\emt_temp,
status -1’.
■ Advice: Create the ‘C:\temp’ directory.
3.2.10.2 BVM1Index - Set Attributes
When the ‘BVM1Index’ is set to ‘Yes’ in the ALE attributes then it indicates
that all fiducial actions which belong together (for a circuit or group) must be
done in the same index step. Because the transport system performs no inter
-
mediate steps between the BVM measurements, the correction for the
particular fiducial arrangement is more accurate, and therefore leads to a
better placement accuracy. This does not mean that the BVM actions must be
done in the first index.
3.2.11 How to use transport settings for FCM
The transport of a pcb through an FCM is carried out by the transport beam
with a carrier set on it. In normal circumstances the default index schemes
(see 3.2.11.1 on page 100) are used. However if a special index scheme is
required it can be specified in the PPS Machine Specific settings.
Every step of the scheme represents a step (move in x-direction) of the beam
in an FCM.
3.2.11.1 Default FCM index schemes
These values are tuned for ‘DFA/BMS’ usage on the FCM (see TABLE 6 on page
101).

1) The second fiducial (left) can be reached in index 1 if the distance between
second fiducial (left) and the SE point is less than 380 mm.
2) The second fiducial (left) can be reached in index 1 if the distance between
second fiducial (left) and the SE point is less than 400 mm.

3) The second fiducial (left) can be reached in index 1 if the distance between
second fiducial (left) and the SE point is less than 400 mm. (Not for FCM MF/
ME)
4) The second fiducial (left) MUST be reached in index 1 if the distance
between the second fiducial (left) and the SE point is less than 400 mm. If not
DFA is not possible.
NOTE: Transport lift-up position equals –440 mm for all schemes. In these cases
‘stopper out’ must be used, so in the Machine or MachineClass attributes
section write: ‘TransportStopperOutUsed’ ‘YES’
3.2.11.2 Specify custom index scheme
If a special index scheme is required it can be specified in the PPS Machine
Specific settings
(see 3.2.11.3 on page 102).
Important parameters which must be defined are described below.
• TransportStopperInX: An integer that specifies the X location of the
transport run-in stopper, relative to the machine origin.
• TransportStopperOutUsed: Specifies whether the run-out stopper
should be used. Possible values are ‘Yes’ and ‘No’.
• TransportBeamLiftupX: An integer that specifies the X location of the
beam liftup, relative to the machine origin.
• TransportNrOfBoards: An integer that indicates the number of boards
on the beam.
• TransportIndexStep: Specifies an array of integer values representing
the index steps (maximum 10 values). The sum of these steps
determine the board pitch.
There is a special order of importance of the specified index schemes, 1
overrules 2:
1. User defined project related transport settings (see 3.2.11.3 on page 102).
2. PPS defines default index schemes.
3.2.11.3 Specify project related transport settings
To specify the transport settings via the GUI of PPS-Pro the following things
must be done. Refer to Specify Project related optimizer settings
(see 2.25.1
on page 61).
To specify a new index scheme press the Add... button and the Add FCM
Transport Setting dialog appears
(see SCREEN 61 on page 103). Just fill in
every field in this dialog. After everything is specified, the name of the index
