Item Description
Example :
To correct the positional deviation covering the whole area of PCB (PCB
Overall Correction)
To improve recognition accuracy, put ducial marks diagonally on two
places of PCB when the 2-point recognition mode is selected. In the case of
3-point recognition mode, put two ducial marks diagonally and one ducial
mark close to one of the remaining corners.

Example 1 : To correct the positional deviation of component placement
points (1-point recognition)
Put a ducial mark on the center of component placement point
or a desired point around the center.
Recommended Position : Center of Component Placement Point
Fiducial Mark
Example 2 : To correct the component placement point
(2-point recognition)
Put ducial marks on the desired two points around the center of
component placement point.
Recommended Position
:
Point Symmetry
It is recommended that two points
(ducial marks) should be located
symmetrically on both sides of the
center of the placement position.
(A-A'/B-B')
•
These ducial marks are used to correct the component position and the
theta (angle).
The 2-point recognition is effective to correct deviated and distorted part
of the printing patterns.

Notes
: (a) PCB support pin position can be moved "10mm" by "10mm" .
(b) Set the PCB support pin on the position where it does not touch
the already placed component.
(c) The gure shows that the PCB is being supported.
(d) The dimensions are those for design reference.
Leave some room for the actual setting.
