2.93 Illumination Setting 11/2004 Edition

2.93.2 Orientation Aid for Selecting Illumination

The following table is derived from empirical values and is therefore only to serve as an orientation

aid. A few materials often exhibit very drastic fluctuations (particularly in the case of CEM1), the-

refore 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. 2

2.93.3 Setting the Illumination

The best illumination selection must be ascertained by using the function "Test fiducials" or the

substrate to be populated. 2

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 SR 502.xx.

During them, the current substrate or PCB is moved onto the processing belt of the conveyor and

mechanically centered / clamped in place. 2

: Select the ICON "Setting illumination"

: In the "illumination" menu select the "Setting illumination" button.

The following screen will appear:

Fig. 2.13.1 Screen: "Setting the Illumination"

NOTE:

Utilize Abschn. 2.12.2 and the table in Abschn. 2.12.3 to select the best type of illumination. 2

: Select the desired illumination level by activating the pertinent radio button.

: Select complete or reduced brightness by activating or deactivating the rectangular field.

: Select the button "Positioning the gantry" and position the gantry over the fiducial that is cur-

rently to be recognized / tested.

: Check the quality of the image on the vision screen (see the section "Teaching Fiducials" in the

User Manual).

: 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.

: If the image of the fiducial is alright, select the button "OK".

As a result, the illumination set is accepted for all 4 gantries.
