Example: To correct the positional deviation covering the whole area of
P.C.B. (P.C.B. Overall Correction)
To improve recognition accuracy, put fiducial marks diagonally on two
places of P.C.B. when the 2-point recognition mode is selected.
In the case of 3-point recognition mode, put two fiducial marks diago-
nally and one fiducial mark close to one of the remaining corners.
Example 1: To correct the positional deviation of component placement
points (1-Point Recognition)
Put a fiducial mark on the center of component placement point or a
desired point around the center.
Recommended Position: Center of Component Placement Point
Example 2: To correct the component placement point (2-Point Recogni-
tion)
Put fiducial marks on the desired two points around the center of com-
ponent placement point.
Recommended Position: Point Symmetry
It is recommended that two points (fiducial
marks) should be located symmetrically on
both sides of the center of the placement
position. (A-A’/B-B’)
• These fiducial marks (two points) are used to correct the component
placement position and the theta (angle).
The 2-point recognition is effectively used to correct deviated and
distorted part of the printed patterns.

P.C.B. Clamping: Mechanical Clamping
Note: The center of the
mark is the reference point.
The reference point and plane differ depending on the contents
of the specifications.
There is no change in the distances between the reference
point and the P.C.B. stopper and between the reference plane
and the P.C.B. locating side clamp (Y pusher).
