are not set appropriately.
(The component body color
and electrode color are not
being set sufficiently.)
1) Set the parameters if not set.
2) Select “Inspection Criteria” - “Extract Electrode Tip,” and click
the [Model Editing] button.
3) Confirm if the electrode color is being set.

4) Set the parameters if not set.
Details of the procedure to adjust component extraction using characteristic parameters are as follows:
The component extraction function extracts something similar to the component by template (model)
matching. The component extraction model is created based on the window setting like the figure below.

For stable component extraction, the characteristic parameters need to be configured so that the rate of
matching between the component extraction model and binarized inspection image becomes higher. To
close to the 100% matching rate, the component and electrode need to be binarized with each
characteristic parameter.
