The following display appears on the screen:
IS NOZZLE DOWN ON COMPONENT CAMERA ?
PRESS <RETURN>
4. Visually inspect the contact point of the nozzle and confirm with "RETURN" (even when
the Z-axis has been incorrectly placed on the plate). The following display appears on the screen:
CENTERING CAMERA HEIGHT 1.3
CENTERING CAMERA HEIGHT; OLD: ............... NEW: ................
ACCEPT VALUE(S) ? (YES / NO)
NOTE
The height value displayed indicates the difference between the PCB lower edge and the surface of the
glass disk, in mm.
5. If the point of contact was incorrect, then select "NO" and repeat the sequence as described above from
point 3 onward.
6. If the point of contact was correct then select "YES". The values determined are accepted.
• The COMPONENT CAMERA MENU is displayed.
7.14.2 Procedure: "EXECUTE THE FOLLOWING POINTS"
NOTE
Carefully take hold of the calibration plate only at the outer edges. Check the calibration plate:
➤ The surface must be clean (no dust, etc.) and without any oxidation layer on it.
➤ All metal surfaces must have the same coloring. Otherwise it is possible that the pin configuration
cannot be recognized during the measurement procedure!
1. On machines up to and including batch identity no. 3, adjust now the conveyor width to the width of the
PCB (handwheel).
2. From the Centering Camera menu select "EXECUTE THE FOLLOWING POINTS". The following display
appears on the screen:
PLUG-IN POSITION NEXT TO COMPONENT CAMERA MUST BE FREE DURING CALIBRATION !!!!
PRESS <RETURN>
• Performance of the action:
Check the space to the left and right of the optic module and remove , if necessary, the feeder modu-
le(s). The coplanarity laser module is not a hindrance when measuring (same height) and therefore re-
mains installed. When these requirements have been fulfilled, confirm with "RETURN".
3. The "DETERMINE CALIBRATION FACTORS" run follows automatically:
• The calibration plate is picked up and centered. The following display appears on the screen:

• Performance of the action:
Teach the calibration plate centrally over the glass disk of the component camera (check the vision
evaluation screen) → press the "END" button on the teach panel.
• The calibration plate is now placed onto the glass disk of the component camera several times from dif-
ferent directions.
4. The calibration factors determined are displayed as follows, for example:
CALIBRATION FACTORS
COEFFICIENTS IN X -.0016 ........ .........
COEFFICIENTS IN Y ....... . ........ ..........
VALUES X3 AND Y3 ARE NOT STORED BUT OCCUPIED WITH 0.
➤ In the case of an error, the screen display appears:
CALIBRATION NOT SUCCESSFUL AFTER FIVE ATTEMPTS
PLEASE CHECK HARDWARE (E.G. AMPLIFICATION, POSITION CONTROL )
• In this case of error the values are not transferred into the computer and the measuring procedure is
not continued.
Troubleshooting:
• Select "END" (function key) → the PCB together with the plate is conveyed to the output conveyor.
• Check the calibration plate for contamination or oxidation.
• Clean the glass disk of the component camera module with a premoistened lens cloth.
• Repeat the measurement (see point 2). If the measurement is correct, point 6 follows.
• If this error recurs during the second measurement run, inform the SMD Service of Siemens AG.
5. If the measurement is correct (no display) then the check measurement is carried out automatically and
the display appears on the screen:
EXAMINATION OF CALIB. FACTORS
➤ The calibration was incorrect: Error message (as above) "CALIBRATION NOT SUCCESSFUL
AFTER FIVE ATTEMPTS".
➤ The calibration was successful: The values are transferred to the main memory and point 7 follows.
6. The measurement "DETERMINE CAMERA CENTRE" follows automatically. The values are displayed,
as for example:
DETERMINE COMP. CAMERA CENTRE
CAM. CENTRE RELATIVE TO REF. POINT X= 423.28 [MM]
Y= -17.94 [MM]
• The values determined are automatically transferred to the main memory.
7. The procedure "DETERMINE ROTATION ANGLE" is automatically carried out:
• After the calibration plate has been deposited the center of the row of leads in both x and y-directions
is determined and the angular offset is calculated from these values.

8. The result is displayed as follows, for example:
DETERMINE ANGLE OFFSET
ANGLE OFFSET; CAMERA <--> GANTRY AXES: -0.33 [GRAD]
PRESS <RETURN>
• Press "RETURN". The angle offset determined (designation in the MA-Data: "PLACEM.ANG. CORR.
AFT.CENTER.) is transferred to the main memory.
9. The function keys as well as the following text are displayed:
SELECT A REFERENCE TRACK !
10. Press the function key of the track which is used as the reference for the component camera center.
The selected values for "POSITION CENTERING STATION" (position of the component camera) are
transferred to the main memory. If "CONTINUE" is selected, the values determined are not saved!
11. Confirm with "RETURN". The COMPONENT CAMERA MENU is displayed.
12. Select "END" (function key). The calibration plate is deposited on the PCB and conveyed to the
output conveyor together with it.
13. The placement head is moved to the waiting position.
14. Remove the PCB from the output conveyor. The main menu is displayed on the screen.
15. From the main menu select now "STORING".

INCREASE DANGER OF ACCIDENT
Before you continue working, note the following text!
➤ The coplanarity laser module should be situated next to the component camera (track-related)!
➤ Special safety regulations apply when working with the coplanarity laser module.
➤ Adhere to all the safety notes/instructions described in the operating instructions, section "Coplanarity
Laser Module", as the laser works in a wave and power range
that is dangerous to skin and eyes !!
➤ The safety device must on no account be bypassed or manipulated in any other way (see operating in-
structions "Coplanarity Laser Module", under "Safety Devices").
➤ The keyswitch must remained locked during the whole procedure!(see also chapter 2 "Safety")!)!

DANGER OF A PLACEMENT HEAD CRASH!
If you release the EMERGENCY STOP function (by actuating the EMERGENCY STOP button or by
opening the protective cover without being prompted to do so) during this measuring routine, the Z-axis -
due to the Z-axis clamping unit - is always in the "lower" position and cannot be raised by the software
while the control is deactivated.
In this situation, the information contained in section 2.2 is to be observed!
