6.3.2. Definition of fiducial mark
The method to define the fiducial mark size for a PCB length is as follows:
Length less than 800 mm: Same as the method to set general boards.
Length is 800 mm ~ 1,500 mm: Set multi work area.
6.3.2.1. Fiducial mark setup
When placing parts on a 0.8~1.2 m long PCB, set 3~4 fiducial marks on it, one of which
must be at the position to which the fiducial camera of the gantry can move.
When setting 3 fiducial marks, they can be set as shown in the following figure.
1) Transfer the PCB to the first workstation.
2) Teach the fiducial mark at center and the right mark.
3) Transfer the PCB to the second workstation.
4) Teach the left fiducial mark.
1: Fiducial mark for ST-Gate2
2: Fiducial mark for ST2F-Work
3: Placement point registered to the ST2F-Work
4: Placement Point registered to the ST-Gate2

Advanced Chip Shooter DECAN S2 Administrator’s Guide
Memo Even though fiducial mark teaching is performed by changing the
workstation, all placement coordinates, fiducial mark coordinates and
the coordinates of various marks are always constant because the
relative distance from the origin is taught.

6.4. Bad Mark Setup
The ‘Bad Mark’ refers to the mark indicated on the PCB to show whether a small PCB in
the array PCB is good or defective. Placement is not performed on the small PCB
indicated defective.
When this <Bad Mark…> button is clicked on, the following dialog box to edit bad mark
data is displayed.
