Appendix 7. Position Correction/Extraction
a-27
The component extraction succeeds if the following five conditions are satisfied.
(1) The component is binarized with the component color.
(2) The electrode is binarized with the electrode color.
(3) The PCB and silk close to the component are not binarized.
(4) The solder close to the electrode is not binarized with the component and electrode colors.
(5) The component is not binarized with the electrode color.

Acceptable
All the conditions from (1) to (5) are satisfied and therefore component extraction succeeds.
Unacceptable
Component extraction fails
because condition (5) is not
satisfied.
Component extraction fails
because conditions (4) and (5)
are not satisfied.
Component extraction fails
because conditions (1) and (4)
are not satisfied.
