FIGURE 13 Workflow Pre-assignment
Action specification 1 can also be used with the extended setup.
!
WARNING: It is likely that PCB 1 contains parts that are not in PCB 2. In this case,
ensure that the parts that are in PCB 1 and not in PCB 2 are present in the
PSI file that is used for the calculation. Otherwise the .con file resulting
from calculation 2 will not contain all setup information.
In general, PCB 2 is a newer version of PCB1. This method works most effi-
ciently if changes are small.
The .con files can also be used to pre-assign nozzles to heads on machines.
3.7.1 Modification of older PSI files
In some older PSI files (Version 6.0 and 6.1) this field is named
‘Philips_AlternatPos’ instead of ‘Philips_AlternatePos’ If the PSI file contains
this error, it is necessary to correct it. This can be achieved by following the
instructions below.
1. Start the Part Information Manager (PIM).
2. Select the Types tab.
3. For all types shown (*, C, CR, J, PackageDesc,...) select the field
‘Philips_AlternatPos’ and change it to Philips_AlternatePos’. To change the
name of a selected field click the Rename button. After all modifications
have been done, save the file.
The procedure that needs to be followed in order to obtain alternate feeding
depends on the type of feeder. Below, the procedure is described for tape,
stick and tray.
3.7.2 Alternate feeding with tape feeders (ACM)
Start PIM and select the part or package that requires alternate feeding.
Select the field ‘Philips_AlternatePos’ and set its value to ‘YES’.

Furthermore set the ‘FeederTypeName’ to <Feeder_id> _ALT. Note that the
<Feeder_id> must be a known feeder, example of a name of such a definition:
ITF2_24_ALT. Currently only the ITF2 feeders are supported. Those ‘*_ALT’
feeders have twice the size of the original feeder, thus ensuring enough room
for the alternate pick position.
3.7.2.1 Adding alternate feeders in the ALE file (ACM)
Note that in the current default ALE files the alternate feeders are not
present. These can be defined as follows:
Add feeder definitions of the alternate feeder(s) to the ALE file, the following
feeders can be defined: ITF2_08_ALT, ITF2_08s_ALT, ITF2_12_ALT,
ITF2_16_ALT, ITF2_24_ALT, ITF2_32_ALT, ITF2_44_ALT and ITF2_56_ALT. Both
name and type must have this name. (Do not use Reel* names) Define twice
the number of slots as the regular feeder has.
Add the feeder(s) to the applicable feederbank definition(s) from the
machines that must get assignments of alternate feeders.
3.7.3 Alternate feeding with stick feeders (ACM)
Start PIM and select the part or package that requires alternate feeding, select
the field
‘Philips_AlternatePos’ and set its value to ‘YES’.
3.7.4 Alternate feeding with trays (ACM and AQ)
Start PIM and select the part or package that requires alternate feeding.
‘Philips_AlternatePos’ and set its value to ‘YES’.
After optimization, the AS generator tries to locate an empty slot in the tray
trolley and it fills this slot with the same part.
3.8 Tracks on Twin Bulk Feeders
‘Tracks’, also known as ‘lanes’, are different feederpositions on e.g. ‘Twin Bulk
feeders’. In the next paragraphs there are examples how to pre-assign a track.
This keyword in the ALE file is used with MPGs that support multi-track
feeders, which contain multiple part numbers. The concept of ‘tracks’ is used
to differentiate the locations in the feeder for part pickup and placement. The
value of this keyword (in below example ‘2’) indicates the number of track
locations that exist in the feeder.
NOTE: For ALE specifications Refer to manual “Description ALE-file 12nc 4022 591
98715”

3.8.1 Pre-assign tracks in a con file
SCREEN 85 Pre-assigning Multi Track feeders
NOTE: Pos 1 (left and right) as well as pos 49 and 50 (left and right) cannot be
used by trays. Position 1 will be used for calibration and position 49 and 50
can not be reached by the lift mechanism of the ACM.
3.8.2 Application of FeederBars
FeederBartypes 1-5 are all used only on FCM I machines whereas
FeederBar_ITF is used only on FCM- II, FCM-MF and FCM-XM machines.
NOTE: The relationship feeder – FeederBar is provided in the ALE file. (The example
provided states which feeders fit on a particular FeederBar.) Furthermore
note that FeederBar4 is designed as a fixed FeederBar for the WVM module
(on a FCM-I machine).
3.9 Pre-assign trays
Tray pre-assignments are possible by using .con files.
