Appendix 7. Position Correction/Extraction
a-32
Details of the procedure to adjust electrode tip extraction using characteristic parameters are as follows:
Electrode tip extraction succeeds if the following two conditions are satisfied.
(1) Electrode binarization ... The electrode is binarized with the electrode color.
(2) Solder binarization ... The solder close to the electrode is not binarized with the electrode color.
