11.2.13 Basically description of all calibration steps
Machine zero point: 11
– The PCB-camera center is the reference at the gantry. All positions at the incremental encoder
of X/Y-axis refer to this camera center.
– A drilling is optically centered with the PCB-camera on a defined position at the calibration tool
support.
– Then the Zero point correction of the gantry axes are changed that if the PCB camera is above
this hole and the Positioncounter shows exactly the value of:
MA nullpunkt_x_PG1 631300 / MA nullpunkt_y_PG1 1298000. ( pg means gantry group)
MA nullpunkt_x_PG2 1368700 / MA nullpunkt_y_PG2 702000 ( See Fig. 11.2 - 2)
PCB camera: 11
– The Pixel size of the CCD sensors of the camera is determined in µm. Measured and calcu-
lated with Ax/Bx/Ay/By calibration values. Saved in KAM_DAT.MA as:XU_Pixel / YU_Pixel
(in 11600 nm Standard-PCB camera SST 5), (in 9900 nm Multicolorillum. PCB camera SST 18)
– The camera center is determined.
– This camera center is now the reference for all Position and Offsets of the gantry!!
– The Mounting angle of the CCD-chip in the camera to the Ma-coordinate system. Saved as
‘Kamera_winkel’ at the Data bloc of the PCB camera in KAMDAT.MA.
Calibration tool position:(optional) 11
– Calibrate the X and Y pick up position of the calibration tool.
Travel range:(optional) 11
– For travel range calibration move the respective axis: -to the Zero-pulse
– Then to the Hardware-limit switch
– Measure the position value at the position counter
– Calculate the position for SW-limit switch (Y +/- 1.5 mm , X +/- 0,5 mm)

Component camera: 11
– The Pixel size of the CCD sensors of the camera is determined in µm. Measured and calcu-
lated with Ax/Bx/Cx/Ay/ByCy calibration values.Saved in KAM_DAT.MA as:XU_Pixel /
YU_Pixel (50000 nm 12 nozzle-comp.-camera SST 12) (81000 nm 6 nozzle-comp.-camera
SST 13) (27500 nm DCA-camera SST14)
– The camera center is determined.
– The Mounting angle of the CCD-chip in the camera to the turning level of the placement star
is measured.Saved as ‘Kamera_winkel’ at the Data bloc of the respective comp. camera in KA-
MDAT.MA.
Sequence segment offset bottom (II): 11
Sequence at one nozzle:
– Is the calibration tool picked with a Nozzle under 0 degree; optically centered and placed with
the PCB-camera is the exact placement position determined (in µm).
– Is the calibration tool picked with a Nozzle under 90 degree; optically centered and placed with
the PCB-camera is the exact placement position determined (in µm).
– Is the calibration tool picked with a Nozzle under 180 degree; optically centered and placed
with the PCB-camera is the exact placement position determined (in µm).
– Is the calibration tool picked with a Nozzle under 270 degree; optically centered and placed
with the PCB-camera is the exact placement position determined (in µm).
– This sequence is repeated. From the 8 placement positions is the average value of the place.
Deviation calculated and taken for the seg. offset.
– The calibration tool do not turn at this sequence.
