7.7.7.5 Testing Illumination Settings
You can set the illumination parameters by calling the 'Illumination' option (see Section 7.6.4.4, Page 7 - 92).
Using the Option “Measure component” you can then measure the component and check your settings with
the aid of the measurement results.
Proceed as follows to test your illumination setting:
●
Using the illumination values suggested in Figures 7.7.9 or 7.7.10 carry out measurement. Measurement
should run through successfully.
●
For each level reduce the set brightness level by 50%.
Measurement should run through successfully.
●
For each level raise the set brightness level by 50%.
Measurement should run through successfully.
If you are not successful with the above procedure, proceed as follows:
●
Starting with the suggested illumination value, increase the brightness of each individual illumination level
for as long as measurement is still successful.
●
Find this upper limit value for each individual illumination level in turn.
●
Starting with the suggested illumination value, decrease the brightness of each individual illumination level
for as long as measurement is still successful. Find this lower limit value for each individual illumination
level in turn.
●
Determine the average value of the upper and lower limit values. This will be the optimum illumination
value.
Example of an illumination test:
–
Settings from the diagram:
flat: 170
middle: 60
steep: 5
Measure the component. Measurement is successful.
–
Reduce setting values by 50 %.
flat: 85
middle: 30
steep: 2
–
Increase setting values by 50 %.
flat: 255
middle: 90
steep: 8
Measure the component. Measurement is successful.

7.7.7.6 General Information on Setting Illumination Values
–
As a rule it is better to overilluminate the component than to underilluminate it. A saturated image is prefer-
able to a low-contrast image.
–
Optimum illumination is attained when only the leads are imaged and the component body is not shown.
–
If you cannot clearly separate the image of the component body from the leads, we recommend to illumi-
nate body and leads equally and then to measure the outline.

7.8 Teaching Fiducials: Additions to the 80F Machine
The placement machine 80F is, in contrast to the 80S machine, a single gantry machine. For this reason the
menu “Teach fiducials” does not include the option “Teach gantry” which you could use with the 80S machine
to select gantry 1 or 2 for teaching.
Both the revolver placement head and also the IC placement head are mounted on this gantry. The camera
system for PCB centering is fitted to the revolver placement head.
All menus are identical to those for the SI80S machine with the exception of this option.
The description of the menu and its options will be found in Chapter 7.5 Teaching the Fiducial.
