Placing the head into the head transport box
If you need to perform further work on this placement head (e.g. replacing spare parts), fit the
placement head to the head mount [03056231-xx].
Installation
Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:
Fit the fastening screws on the other side of the module, if needed (see above).
Make a note of the force values for the new module. These force values can be found on a
label at the side of the module.
Make sure that the assembly position is correct.
Perform a head calibration.

8.10 Calibration
Service Manual SIPLACE X-Series S (from Hxxxx) 01/2021 279
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-
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.
