Nozzle scanning
The dialog for configuring the nozzle scanning under Settings – Machine options contains two
new self-healing actions: Replace and Clean and replace.
Figure 10-34: Dirty nozzle – Machine options
State overview of head segments
The State overview dialog for the head segments contains the new state disabled: nozzle dirty.
Preventive maintenance
Additionally to the above changes, the Preventive maintenance view has been extended. Please
refer to section 10.13.13.
10.15 Enhanced Automatic Feeder Pitch Detection
Compatible mode: Complete
The existing Automatic feeder pitch detection function has been enhanced in this station
software version.
The station software can now increase the pitch automatically to the measured value if the
expected pitch is undefined (value 0). The station software performs frequent measurements of the
pitch (every 700 placements) if the expected pitch is undefined, to continuously verify measured
pitch values and to minimize the impact of wrong automatic pitch increases.
NOTICE
This function has an impact on the placement performance.

10.16 Improved Face Down Recognition for Diodes
Compatible mode: Complete
Small SOT and SOD diodes sometimes are placed lying on their back on the boards what may
lead to problems and high reject rates. Therefore, the SIPLACE Vision functionality for the face
down recognition has been improved. As of station software version 709.1, this feature uses the
different appearance of the gullwing leads on the top and bottom of the component to detect which
side is facing the camera. In lower station software versions, this measurement will be ignored!
SIPLACE Vision performs a measurement in two steps, optionally with different illumination
settings. In the first step the position of the gullwing leads is determined; in the second step the
bend of the leads is recognized.
Component face down -> inner lead ends
are bright
Component correct -> inner lead ends are
dark
The face down recognition can be started from the Options list with the Recognition of flipped
components button. A wizard helps guiding the operator when entering the required data.
The feature can be combined with multiple field of view measurements and Pin1 detection but not
with pattern matching and glue inspection.
NOTICE
The face down recognition only works if the inner lead ends have a sufficiently constant
position to the middle of the component. If there are large tolerances for the component
body, it might happen that the component body or the contact area is evaluated instead
of the inner lead ends. This would then lead to faulty results (body to small -> area bright
-> a correct component is rejected; body to large -> area dark -> a face down component
is not recognized).

10.17 Changing Lower Activity Level to SIPLACE Service
Compatible mode: Complete
For any activity on an activity level lower than SIPLACE service the activity level can now be
changed to SIPLACE service. To do this modification or changing back to a lower activity level,
the SIPLACE service activity level is required.
In the dialog for changing the activity level, SIPLACE service is always offered. This dialog is
displayed for all functionalities for which the default activity level is not SIPLACE service.
10.18 Different Activity Levels for Handling Segment States
Compatible mode: Complete
Three buttons are now offered for handling segment states in the Manual operation view: Enable,
Disable and Do not use. The accessibility of the buttons changes according to the selected
segment.
Disable is available from the Advanced production activity level. Do not use is available from the
Basic production activity level.
10.19 Improved Board Identification
Compatible mode: Complete
The process for identifying a board when loading it into the placement machine has been improved
and now offers a more reliable barcode reading in the input section of the conveyor.
The X/Y barcode position on the board and the location on the current or opposite board side can
be defined in SIPLACE Pro. This information is sent to the station. The conveyor software
calculates the correct moment to trigger the correct barcode reader and proposes the correct
trigger setting automatically.
The operator can select if the proposed barcode reader setting shall be used. It is also possible to
add a constant offset / time to individually adjust the trigger of barcode reading. This parameter will
be preset automatically and refers to the time it takes to move the board to the input section of the
machine. The parameter is editable on the station software GUI under Service – Conveyor
configuration – Lane x – Parameters.
It is possible to combine an external barcode reader with the board camera for reading the
barcode.
The maximum number of characters for the barcode has been increased to 255.
Restrictions
Barcode fiducials and barcode-controlled production cannot be combined.
