7. Applicable PCB Size : 50 × 50 to 610 × 460 mm
(Four Corners : R1 to R1.5 mm)
Thickness : 0.3 to 5.0 mm
Warpage : The following two requirements should be met.
• 0.2 mm or less per 50 mm (unit length)
Example: The warpage must be 0.8 mm or less when the PCB
size is 200 mm.
• Max. 1.0 mm
Example: The warpage must be 1.0 mm or less when the PCB
size exceeds 250 mm.
Warpage
F1E2
Mass : Max. 2.5 kg (completed PCB)
However, for the size X of 260 mm or less, the max. mass is 1.5
kg (for a completed PCB)
Material : Glass Epoxy
Ceramic (Option)
Notes : (a) Consult our marketing department or sales agency for Glass
Epoxy with light color.
(b) Depending on the PCB material, shape, warpage, mass or surface
condition (gloss), etc., it should be tested whether or not the PCB
can be transferred, or the components can be placed normally, to
confirm.

Note : The shadowed areas show the areas where a cutout should not exist.
When a cutout or a hole exists in the shadowed area, perform a PCB
positioning test and confirm that the PCB can be positioned normally.
9. Correction Method
for PCB Location
PEC Recognition
• By recognizing the fiducial marks using the PEC camera, positional
deviation covering the whole area of PCB and expansion of the printed
patterns on PCB can be corrected.
• To correct the positional deviation covering the whole area of PCB,
fiducial marks must be put on two or three places of PCB (Zones 1
through 5). Two fiducial marks are required for each unit PCB of a
multi-unit PCB.
• To correct the positional deviation of component placement points, put
one to two fiducial marks on the PCB. In this case, it is recommended
that two fiducial marks be located symmetrically such that the center of
gravity (the center of the fiducial marks) becomes the center of the
component placement point.

Overall Correction)
To improve recognition accuracy, put fiducial 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 fiducial marks diagonally 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

F1E6
Example 2 : To correct the component placement point
(2-point recognition)
Put fiducial marks on the desired two points around the center
of component 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 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.
