5.9 Additional Repick
Compatible mode: Complete
To prevent a machine stop, this option allows an additional repick although the value for repicks is
set to 1 in SIPLACE Pro.
An additional repick will be performed in the following cases, provided that 500 successful repicks
have been performed before (valid for each case):
– after SIPLACE Vision has recognized a material defect
– after an empty tape pocket was recognized
The option is set in the SetupCtrl.xml configuration file.
5.10 Handling of Frequent Vision Errors
Compatible mode: Complete
The display of detailed messages for frequent Vision errors has been enhanced.
In the Overview tab the same information on component and error rate is displayed as before.
In the Dumps tab the dump files are displayed. Beneath the list it can also be filtered by error
numbers and their frequency.

In the Error distribution and help tab a diagram displays all errors. If an error is selected by
clicking on it, corresponding help assistance is displayed to the right.

In the Segment distribution tab the same diagram is displayed but additionally with the counter
for the respective segment.
5.11 Enhanced Placement Error Analysis
Compatible mode: Complete
In the Board view, an inspection option can be selected for each placement position. A Vision
image can be taken of the components before pickup and after placement on the board and the
dump files can be stored. However, with these analysis options it is not possible to differentiate if
the placement problem occured on the way to the placement position, during placement or after
placement. For this, an inspection of the component position is required for one or several
placement positions immediately before the placement process takes place (before the z-axis is
started for placement).
The diagnosis functionality in the Board view has been enhanced by the Compare Image before
placement option.

Figure 5-9: Placement error analysis options
After this option has been selected for one or several placement positions, the placement process
is interrupted before the z-axis starts to place the component and a new measurement with
reduced acceleration is started. The reduced acceleration shall prevent further slippage of the
components. After the additional measurement, the component is brought to the placement
position with reduced acceleration and will be placed with the z-axis acceleration that is defined in
SIPLACE Pro.
The two measurements (standard and before placement) can be compared and evaluated via the
inspection function for Vision measurements on the GUI. A possible slippage of the component can
thus be clearly recognized. Additionally, the results of the additional measurement are entered in
the board history files. This allows a statistical analysis over a longer period.
5.12 Robust Dual Gantry Measurement
Compatible mode: Complete
The dual gantry measurement procedure has been improved.
In a dual gantry configuration, the station software performs a dual gantry measurement every 5
minutes in order to correlate the gantries' positions and correct the positions, if necessary. Until
now, if a fiducial was manually taught or the wrong fiducial was detected by one of the gantries, the
resulting error was applied to all boards produced within the next 5 minutes.
To prevent such process errors, the dual gantry correction will now not be transferred to the next
board(s) if any of the fiducial positions were taught by the operator. This includes all cases in which
the first fiducial measurement failed and the operator intervened via a detailed error. Instead, a new
dual gantry measurement will be performed for the next board.
