1: Mask Fiducial
Set this parameter to "Use For Every Board" or "Use For Once" when using mask fiducial marks for position alignment by
vision recognition. If not using mark recognition then set this to "NotUse". When set to "Use For Every Board", position
alignment by mark recognition is performed each time a board is loaded on the conveyor. When "Use for one" is selected,
position alignment by mark recognition is performed only when the first board is loaded. Pressing the [Edit] button at the
upper right displays the dialog box shown below. Select the desired item from the Mark Fiducial drop-down list.

2: Fiducial Type
When "Mask Fiducial" is set to "Use For Every Board" or "Use For Once", select the fiducial type (number of fiducial
marks to be recognized) from among "1 Point" to "4 Points". These marks can be different in shape and size from each
other. Pressing the [Edit] button at the upper right displays the dialog box shown above. Select the desired item from the
Fiducial Type drop-down list.

3: Fiducial Position
This parameter sets whether to share the fiducial mark position with the board and the mask. Pressing the [Edit] button at
the upper right displays the dialog box shown above. Select "Board&Mask Individual" or "Board&Mask Common" from
the Fiducial Position drop-down list.
When "Board&Mask Individual" is selected, the Fiducial Position, Fiducial Type and Standard Position parameters can be
set individually on the board and mask.
When "Board&Mask Common" is selected, the Fiducial Position, Fiducial Type and Standard Position parameters are
shared with the board and the mask.
A confirmation message box appears when you select "Board&Mask Common". Pressing the [OK] button in the message
box copies the fiducial mark setting (Fiducial Position, Fiducial Type and Standard Position parameters) into the board
fiducial mark setting.

■ Board and mask mark positions are on the same coordinates
■ Board and mask mark positions are on different coordinates
Board mark
Positioning marks on board and mask
Image processing is first performed to detect
the amount of position shift with reference to
the theoretical mark positions on the board and mask.
Based on this, the board and mask positions
are determined so that their marks are exactly aligned.
Image processing is first performed to detect the
amount of position shift with reference to the
theoretical mark positions on the board and mask.
Based on this, the board and mask positions are
determined so that their centers are exactly aligned.
Then, angular positioning of the board and mask is
corrected respectively, so that a line connecting
the two marks is aligned with the line connecting
the theoretical positions of the marks.

NOTE
When the Fiducial Position, Fiducial Type and/or Standard Position parameter are changed by either the board
fiducial setting or mask fiducial setting or teaching, then that change is automatically reflected in the other.
4: X, Y (mm)
Enter the XY coordinates of each fiducial mark relative to the mask origin in millimeters. You can perform teaching with
the [Teach] button.
TIP
For details on teaching, see "1. Teach and trace" in Chapter 6.
5: Mark No.
Enter the mark No. of each fiducial mark. (Mark No. should be registered in advance on the Mark screen.)
6: Name
When the mark No. is entered, the corresponding name is automatically displayed here. (Mark name should be registered
in advance on the Mark screen.)
