The position correction color
is not appropriate.
1) Select “Tool” - “PCB Image Management.”
2) Click the [Model Editing] button.
3) Confirm that the position correction color is set appropriately.
4) Change the color if not set appropriately.

3. Extraction offset confirmation procedure
After conducting a PCB test using an adjustment image, whether the extraction offset occurs or not on
the component number (component number group) in which an inspection fault has occurred is verified
based on the shape of the histogram of the model editing screen according to the following inspection
items.
When the extraction offset occurs, refer to the component extraction procedure and the
component tip extraction procedure of appendix section 5 and 7, respectively to adjust to
eliminate extraction offset.

For the component body
window:
- Component offset –
Offset X [Absolute
value]
- Component offset –
Offset Y [Absolute
value]
All the measured
values of good
components must be
within the default
inspection criteria.
IC
Connector
Resistor array
The width of the land
for the electrode width
is less than 120%.
Electrode window:
- Side overhang
- End overhang
The distribution width of
the measured value of
the good component
must be 20% or less.
Example 1: Verifying extraction offset of 2-pin mini mold
On the left figure, the values are within the inspection criteria so it is judged as no offset. On the center
and right figures the values are not within the inspection criteria so they are judged as offset.
