8.7 Calibration
Overview
With the calibration of the component camera the following values are determined:
the relationship of "camera pixel size to resolution of machine measuring system (X,Y)", the "cam-
era center point in X and Y direction" and the "torsion angle of the CCD sensor in the camera". This
is following by determining the head offset and the segment offsets for the top and bottom.
Head offset: the head offset is the distance between the PCB camera and the nozzle (seg-
ment1). The target is a fixed value (X=0 and Y=‑105mm) to which an offset value (from the
head calibration) is added.
Segment offset top: the top segment offset involves turning the calibration tool in the compo-
nent camera in 0°, 90°, 180° and 270°. The value determined is that of the rotating center of
the nozzle tip in relation to the component camera center in the X and Y direction.
Segment offset bottom: the bottom segment offset involves recording and measuring the
calibration tool in the 0°, 90°, 180° and 270° positions. The value determined is that of the ro-
tating center point of the nozzle tip when the Z axis is extended in relation to the PCB camera.
Segment1 forms the reference (X=0,Y=0) to the other segments.

Select Heads and cameras.
Click on the Continue button.
Follow the instructions on the next pages:
On the next page, select the gantries on which
the heads to be calibrated are located and then
click on the Next button.
The next step is to check the calibration condi-
tions (nozzle, calibration tool etc.). Follow the in-
structions provided.
After this step, calibration will begin. All required inter-
mediate steps (head height etc.) will be performed
automatically.
