8.4.3 Setting the segment offsets
► Select the menu Service => Die handling calibration.
► Select the Segments offset calibrationtab .
Fig.239: Die handling calibration => Segments offset calibration
► Select the Illumination button and set the lighting so that the wafer content is recognizable
with as much contrast as possible.
► Then close the illumination window.
► Position the Teflon tape under the wafer camera.
► Click on the Stamp mark for segment 1 button for segment 1 or the Stamp mark for seg-
ment 2 button for segment 2.
Fig.240: Nozzle print on Teflon tape
The relevant segment moves down onto the Teflon tape and creates a print. In an ideal case, the
center point of the print corresponds to the camera center point (red cross in the Vision view). If
you are unable to recognize the print, you may need to adjust the illumination.
If the print deviates from the camera center, you can correct the segment offset in the X and Y dir-
ection.

8.4.4 Correcting the segment offsets
The offsets for segments 1 and 2 can be corrected with the parameter Offset segment 1 or Offset
segment 2 (see15.3.2.4 "Calibration – segment offset calibration in X direction" [}379]).
Alternatively:
Fig.241: Adjusting nut and counternut for mechanical X and Y setting
Alternatively, the setting can be mechanically set via the adjusting nuts (1) and counternuts (2) at
the segments.

8.4.4.1 Correction in X direction (segment 1)
There are two options for correction in the X direction (rotation direction of flip head):
●
(1) Correction of X offset in the SWS GUI via the parameter Offset segment 1 (see 15.3.2.4
"Calibration – segment offset calibration in X direction" [}379]).
A positive entry moves the print to the left while a negative offset entry moves the print to the
right.
●
(2) Move the print via the adjusting nut at the segment.
To adjust the adjusting nut, you first need to loosen the counternut (see below).
Fig.242: Segment 1 - loosening the counternut (X direction)
► Hold the adjusting nut with the fork wrench and open the counternut with the Allen key.
Fig.243: Segment 1 - turning the X adjusting nut
Turning the adjusting nut enables you to correct the segment offset:
Setting valid for segment 1:
●
Moving the print to the right -> turn the X adjusting nut clockwise.
●
Moving the print to the left -> turn the X adjusting nut anticlockwise.
