Appendix 9. Land Inspection Adjustment Procedure
a-51
Inspection item 7. Land exposure
Based on the land color detected in the land window, inspect if land is being exposed.
If false call or overlooking still remains in the inspection result, “Land exposure” is displayed.
The inspection result image, cause, and repair method of land exposure are as follows:
Inspection result
Component image (PCB test)
Land exposure
Cause
Confirmation/repair method
When position does not match between the actual land and extracted land:
The land window is not positioned
appropriately.
Refer to Appendix 7.2.
The land window of the peripheral
components of the applicable component
is not positioned appropriately.
Refer to Appendix 7.2.
The fiducial correction is not appropriate.
Refer to Appendix 7.1.
The position correction color is not
appropriate.
Refer to Appendix 7.2.
When position does not match between the actual component (electrode) and extracted component
(electrode):
The component is not extracted in an
appropriate position.
Refer to Appendix 7.5.
The electrode tip is not extracted in an
appropriate position.
Refer to Appendix 7.7.
The electrode side is not extracted in an
appropriate position.
Refer to Appendix 7.6.
The electrode window is not sized
appropriately.
Refer to Appendix 7.5.

Characteristic parameters are not set
appropriately.
1) Move to the “Criteria Setting” tab.
2) Select “Inspection Criteria” - “Land Exposure”, and click
the [Model Editing] button.
3) Edit characteristic parameters using the color table editing
tool so that metal portion of the land (such as copper foil) is
extracted.
The inspection criteria are not set
appropriately.
Refer to Appendix 10.1.
