* In the case of board data which needed partition mount, “Board” cell of “Type” column is
changed to “Board (First half)” and “Local” cell of no.1 row is changed to “Board (Second
half)”. (However, after mount data is edited, view of grid is not reflected until board data is
reselected)
* The Visual editor of P-Tool does not support board fiducial for “second half mount”. After
converting to YGX board data, add board fiducial for “second half mount” by the board
editor.
4.2.3.2 Block fiducial
Block fiducial is not able to use.
(It is not practical because block fiducial marks have to be located at the recognizable
position in both “first half mount” and “second half mount”)

4.2.3.3 Local fiducial
Local fiducial corresponding to “first half mount” has to be recognizable at “first half
mount”, and local fiducial corresponding to “second half mount” has to be recognizable at
“second half mount”.
Set local fiducial data to after No.2. No.1 is not able to use as local fiducial because it is
used as board fiducial for “second half mount.
Example: Unusable board data (Data check error occurs because local fiducial
corresponding to “first half mount” is not recognizable at “first half mount”)
4.2.4 Bad mark
When using bad mark, be careful following points.

* Bad mark recognition results at “first half mount” are taken over to “second half mount”.
* When starting halfway continue, return board to the main stopper position if board exists at
the exit stopper position, because bad mark has to be recognized at “first half mount”.
* When “Sort Type” is set in “Near mark”, the near mark search is executed at each of “first
half mount” and “second half mount”.
Example 1: Usable board data (The local bad mark corresponding to mount data of “second
half mount” is recognizable at “first half mount”)
Example 2: Unusable board data (Data check error occurs because the local bad mark
corresponding to mount data of “first half mount” is not recognizable at “first half mount”)
Bad mark type Cautions on setting

They have to be recognizable at “first half mount” because they
are always recognized at “first half mount”.
Local bad mark If local bad mark that can be recognizable at “first half mount”, it is
recognized at “first half mount”. If local bad mark that cannot be
recognizable at “first half mount”, it is recognized at “second half
mount”.
Therefore local bad mark which used at “first half mount” has to
be recognizable at “first half mount”. Local bad mark which used
at “second half mount” has to be recognizable either “first half
mount” or “second half mount”.
When the "bad mark take over" function is effective and the board
data has only "first half mount" parts, all bad mark has to be
recognizable at "first half mount".
