Closes the <Fiducial Position & Mark> dialog box without saving the fiducial mark
data.
6.3.1. Fiducial Mark Setup Order
1) Block Setup
Omitted for non-block PC
2) Position Type’ setup
3) Mark Position’ setup
Select a fiducial mark in the <Mark Position> group.
Click the <Move> button to move the fiducial camera to the selected fiducial mark.
Perform adjustments so that the center of the fiducial mark falls on the crosshair center
of the SMVision window.
Click the <Get> button to input the coordinate of the fiducial mark.
4) ‘Mark List’ setup
5) ‘Form Data’ setup
6) Outline check
Click the <Outline> button to check if the outline seen in the SMVision window falls
on the fiducial mark outline.
If not, revise the “Shape Information’.

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

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.
