Calibration of SIPLACE HS-50
Calibration of the component camera
With this menu we determine:
Ø the mechanical Pixel size of the CCD-sensor in
µm.
This is calculated with the calibration factors
„Kalibrierfaktoren“ AX/BX/CX ...
Saved in REAL.MA
XU_Pixel / YU_Pixel. (in 24000 nm)
Ø the camera center pixel.
Ø the angle of the CCD-Sensor according the
turning level of the Placement Star.
Saved in REAL.MA „Kamera_offset_Winkel“
Ø the camera offset is set to Zero (because the
camera center is the reference for calibrations).

Segment offset II
The sequence at segment offset bottom / II is:
Ø We center the actual calibration tool position
with the PCB camera. Then we pick it up
and center it optically in the component
camera. The moving distance and the com-
ponent offset is taken for the result.
Ø With segment number 1 we calculate the
distance between the two camera centers;
called (RV-head) camera (PCB) camera
offset. This is saved in REAL.MA in the data
bloc of the PCB camera.
KAMERA_OFFSET_X
KAMERA_OFFSET_Y.
Ø All other segments get an OFFSET to this
segment 1;called segment offset II of this
segment .
Ø This is saved in PIP_OFF.MA file

Pcb camera - component camera offset
With segment number 1 we calibrate the distance
between component -and PCB-camera center;
called (RV-head) camera - (PCB) camera offset.
The machine center optically PCB camera the
calibration tool in the “tool pocket”. This
calibration tool is picked up with segment number
1 and optically centered in (RV) component
camera.
The travel distance of PCB camera from the
measured tool position to the measured actual tool
center position is measured.
This measured distance is set for the camera -
camera distance. There is not maximum limit set
for.
The component camera center is set for the
reference position.

Segment offset I
0°
180°
With this menu we determine:
Ø the mechanical distance between center of the
component camera to the center of the turning axis
of the segment in µm.
This is calculated with a 180° turning of the
calibration tool on the nozzle.
Saved in PIP_OFF.MA.
Ø Picture 1 segment with calibration tool in 0° under
the camera. DP station turn than in 90° steps and
on each angle this measurement is done.
Ø First measurement results from 0° and 180° taken
to calculate turning axis.
The plausibility check is done with
the results from 90° and 270°.
Ø Picture 2 segment with calibration tool in 180°
under the camera.

Calibration of SIPLACE HS-50
Machine zero point
Ø With the PCB camera we center the hole
drilled on the fixed transport rail. This position
has fixed X&Y coordinates.
Ø At this mechanical fixed position we calibrate
all gantry axes of 1 placement group area
(maximum is 2 gantries).
Ø With the calculation we consider the actual
valid camera - camera offset.
Ø The Zero point corrections of all gantry axes
are changed about the measured offset.
Ø When the center of the component camera is
exactly above the drilled hole. The axis position
counter shows you the value of
MA_Nullpunkt_X_pg1 /
MA_Nullpunkt_Y_pg1 .
