8.10 Calibration
Overview
The following values are determined during calibration of the component camera:
●
Relation of camera pixel size to resolution of machine measurement system (X, Y).
●
The camera center point in the X and Y directions
●
Rotation 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-
ment1). The target is a fixed value (X=0 and Y=‑105mm) 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.
Segment1 forms the reference (X=0,Y=0) to the other segments.

You can choose between Combined steps
and All steps.
The procedure for All steps is described
below.
► Go to Select calibration steps and se-
lect All steps
.
► Choose Heads and cameras.
► On the next page, select the gantries
on which the heads to be calibrated are
located and then click on the Next
but-
ton.
Follow the instructions on the next pages:
► The next step is to check the calibration
conditions (nozzle, calibration tool etc.).
Follow the instructions provided.
After this step, the calibration will begin. All
required intermediate steps (head height
etc.) will be performed automatically.
