The following table is derived from empirical values and is therefore only to serve as an orienta-
tional aid. A few materials often exhibit very drastic fluctuations (particularly in the case of CEM1),
therefore the best illumination has to be ascertained through testing. In each instance this is done
by selecting the setting for illumination during the course of a sample placement with recognition
of the position of the pertinent PCBs or ceramic substrates.

In case of doubt, the best illumination selection must be ascertained by using the function "Test
the fiducial" or the substrate to be populated.
NOTE:
The processes which must be executed prior to setting the illumination are described in detail in
the section "Teaching Fiducials" or "Teaching Synthetic Fiducials" of the User Manual, Software
version SC 502.xx.
During them, the current substrate or PCB is moved onto the processing belt of the conveyor and
mechanically centered / clamped in place.

NOTE:
Utilize Section 2.2 and the table in Section 2.2.2 to select the best type of illumination.
Å Select the desired illumination level by activating the pertinent radio button.
Å Select the complete or the reduced brightness by activating or deactivating the rectangular
field.
Å Select the button "Positioning the gantry" and position the gantry over the fiducial that is cur-
rently to be recognized / taught.
Å Check the quality of the image on the vision screen (see the section "Teaching Fiducials" in the
User Manual SC 502.xx).
Å If the image of the fiducial is still not optimal, select another illumination level or, if appropriate,
change the brightness too and select the button "Positioning the gantry" again.
Å If the image of the fiducial is alright, select the button "OK".
As a result, the illumination set is accepted for all 4 gantries (HS-50) or both gantries
(S-25 HM).

DANGER
Only the line engineer or customer’s service engineer trained at Siemens is permitted to remove
and re-install the camera in the manner described below, including carrying out the preparatory
and final steps.
NOTE:
Depending on the thickness of the substrate or PCB, during the installation of the camera it may
be necessary to place the distance plate from the retrofit kit under the camera or not.. This is al-
ways the case with all of the gantries of the machine.
The distance plate will be delivered during the course of the retrofitting of the Multicolor camera
and has already been installed.
The following data items are recommendations to ensure an optimal placement process:
In most cases, adequate imaging quality will still be achieved even it work is done outside the
ranges indicated above.
With the spacer plate removed, system fiducials can still be adequately recognized.
