Pick-up GF (component)
Pick&Place placement head
Pick up GF (component)
Measure component
Check GF (component), press
Return for next meas. step
Display component
Check GF (component), press
Return for next meas. step
Measure GF (component)
Repeat meas. process several
times (move component onto
nozzle to simulate picking up
different components)
and check results
Assemble component
several times
Important note:
The manipulation of
components at the station
must remain the exception,
rather than the rule.
In general, only a few
components have to be
changed.
1. Handling error: pick-up angle,
nozzle type, CO on nozzle etc.
2. Display component
3. Modify lighting
4. Modify measuring modes
and measuring parameters
5. Modify component dimension
6. Modify pin/ball contrast
7. Modify pin/bal
dimensions
8. Program contrast
(program table)

*) LEAD with combined analysis windows for each row of pins replaces the CORNER measuring
method.
Measurement of the spacing is replaced by measurement of the (standardized) lead deviation.
If one or more of the results are outside the tolerance, the component will not be placed.
If the component cannot be centered correctly, additional measuring methods may be omitted.
You should, however, carry out all the rough centering steps since these reduce the size of the
measuring window.
– In the ’Test component’ menu, the components are optically centered in the individual measur-
ing steps, via the ’Check component’ function, but the results are not output.
– In the ’Test component’ menu, the components are optically centered in the individual measur-
ing steps, via the ’Measure component’ function, but the results are not output.
– If the components are larger than 32 mm x 32 mm, a multiple measurement will be carried out
