5.9 External reading of the machine ID
The machine ID can be read by the SIPLACE Pro software as for version 3.0. (station computer
interface). The Machine ID is
prerequisite for the following software:
- Setup Center as for version 2.2
- OIS as for version 4.1
- SIPLACE Explorer as for version 2.1
You are asked for the machine id when installing the station software. For details see the installation
manual (00193796-xx).
5.10 Improved placement quality
Placement quality has been improved in the following respects:
- Minimization of missing components on the board
- Detection of missing components on the board
- Minimization the risk of head crashes
This was achieved by implementing additional functions.
- vacuum check for detecting placement errors
- any monitoring functions:
valve plunger position
lower light barrier
15 VDC power supply
upper light barrier of the DLM head
stepper motor boards (short cut monitoring)
dp switch-in function
Note:
On the GUI, additional error messages could appear during the placement process. Because
of the additional monitoring functions which have been implemented to improve the placement
quality.
Vacuum check
In order to detect missing components and placement errors, an additional vacuum measurement
and the associated evaluation have been implemented.

Software Version Description, Station Software 505.05 07/2008 Edition
1. The vacuum values are compared after the component has been picked up and before it is
placed. If the vacuum value is significantly larger before placement, it is assumed that the
valve plunger is in an incorrect position, which may cause components to be lost.
The board is stopped in the output conveyor and an error message is issued.
The board must be checked for placement errors.
2. During the reference run, the threshold for the vacuum check is intensified.
Note:
If the vacuum check causes error messages with respect to the vacuum value appear too
frequently, please consult your service engineer.
Restrictions
- The vacuum check only works on modular DLM heads.
- The vacuum check and the Z height check both depend on the nozzle. They only apply to the
nozzle types specified in the database.
- The additional checks may lead to a higher rejection rate.

5.11 Revision of the traceability feature
Compared with Version 503.04 of the traceability feature, data provision for the XML files which are
generated has been improved and key aspects of the functionality have been corrected (see below).
The behaviour of the traceability feature has been changed. The XML files are only written when the
PCB leaves the station (either in the normal manner or if it is removed by hand). Problems may
occur if the machine is switched off while a PCB is still in the station.
Other improvements:
- Stabilization of the software
- Extension of the logging mechanisms
- Traceablity Version 1.1 or 2.1
- Manual input of the PCB barcode is documented in errorLabel
- Indication of whether a subpanel was inked out or not (omit = TRUE / FALSE)
- Activation of the traceability option
- Activation of the GEM option
- Modified default setting for the scanning of barcodes if the previous setup was identical
5.11.1 Extension to support traceability version 1.1 or 2.1
Previously, the PCB barcode was logged in the XML file when the traceability data was output. It
was however not clear how this data was entered in the output (automatically after successful
barcode scanning or by manual entry). Manual entry often resulted in duplicate or missing XML files
from a given machine. For this reason, manual entry of the PCB barcode is now documented in the
file using the errorLabel (4096).
In addition, information as to whether subpanels were inked out or not is also logged.
This is done by assigning the additional attribute omit to each subpanel:
omit = "false" Î Subpanel was assembled
omit = "true" Î Subpanel was inked out and was not assembled
