Example 2: Unusable board data without block distribution (Data check error occurs
because X coordinate or R coordinate of block offset is set)
4.2.3 Fiducial
4.2.3.1 Board fiducial
One set of board fiducial is required for the position that can be recognized at “first half
mount”, and another one set of board fiducial is required for the position that can be
recognized at “second half mount”.
Set each board fiducial to [Board] - [Fiducial] tab as following.
(A): Board fiducial for “first half mount” --- Set to “Board (First half)” row
(B): Board fiducial for “second half mount” --- Set to “Board (Second half)” row

* 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”)
