・ Edit the Auto Extraction Result
The auto extraction of lands may not be successful if the bare PCB is applied with solder
leveling. Use the system learning feature to teach it the colors of the lands. The more lands the
system learns, the more precise the auto extraction can be.
1.
Click [Edit Extraction].
2.
The extraction editing tool starts up.
Select the [Show extracted land area] checkbox. The land pixels
successfully extracted are shown in aqua color.

Click unextracted land areas on the image display area.
Refer to <Color Table Edit Tool> on “2.15.3 Editing a Model”.
Click [Initialize] to return to the pre-editing image.
4.
Click [Update]. The land window is auto extracted and displayed.
5.
If irrelevant locations e.g. the lands of other components in the
surroundings are extracted, select the [Delete an unnecessary
land.] checkbox and click [Update] again.
Repeat Steps 3 to 6 until only the land windows for the relevant
component are extracted.
6.
Click [Close] to quit the extraction editing operation.

2.4.5.3 Electrode Group Setting
This section describes the creation of electrode windows and setting of electrode groups.
Drawing windows is not required for chip-type components (i.e. chip resistors, chip capacitors
or other chip components), since the electrode windows are automatically extracted.
1.
Set groups for each electrode.
Divide electrodes of different shapes and sizes into separate groups,
since the electrode inspection criteria are specified by the unit of
group.
The example below shows the group setting for an SOP with the
electrodes on both ends (specified as Group 2) larger than the
others.
The electrode group default setting is provided depending on
the land window size.
