Board fiducial and local fiducial functions
1. This function runs board
fiducial recognition and
calculates the amount of offset
for correcting the board
deviation that may occur when
clamped on the print table.
2. This function uses board fiducial
recognition results to correct the
board deviation that may occur
when clamped on the print table.
It then recognizes the marks at
the local fiducial positions that
were preregistered.
3. If there is no elongation or
distortion on the board then no
local fiducial recognition offset is
issued. But if elongation or
distortion is present, the local
fiducial recognition offset (only in
XY direction) is added unchanged,
to the board fiducial offset.

TIP
When there are multiple positions on the board where you want to essentially maintain satisfactory printing accuracy
and the local fiducial function is used on each of these positions, the average of the recognition offset amount for
each local fiducial mark is used as the correction offset.

1. No.
Shows the local fiducial No.
2. Skip
Sets whether to run or to skip the local fiducial function for the specified No. Clear the check box if running the local
fiducial function.
3. X(mm), Y(mm)
Sets the position for the local fiducial mark position for the specified No. The coordinate reference position is the same
as the board fiducial mark.
4. Mark No.
Specifies the mark No. to use for recognizing the local fiducial mark of the specified No.
5. Name
Shows the name of the mark data specified in the mark No.

CAUTION
Always set the board fiducial function to "Use" when using the local fiducial function. The board fiducial function is
disabled if set to "NotUse".

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.

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.)
