11.1 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".
After that, the head offset and the segment offsets for the top and bottom are determined.
●
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.
11.1.1 Calibration procedure
► Machine zero point
► Board camera
– Camera coefficient (illustration scale in nm/pixel)
– Calibration of PCB camera center point
– Calibration of PCB camera rotation to machine coordinate system
► Calibration tool position (optional)
► Travel distance X/Y axis (optional)
– Calibration of min/max gantry travel distances
► Placement head
– Pressure control valve (SIPLACE C&P20P2)
– Camera coefficient (unit nm/pixel), angle
– Head offset (offset PCB camera to component camera)
– Segment offset II (bottom)
– Segment offset I (top)
► Nozzle changers
– Calibration of pickup position for all magazines
– Calibration of pickup height
– Calibration of reject position

Fig.118: Automatic calibration
► Choose Heads and cameras.
► Choose the Next 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 but-
ton.
► 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.
