Figure 3 Unavailable areas for setting up the support pins (Board size: L-Wide)
Note 1: When the PWB transport direction is reversed (leftward flow), the unavailable areas for
setting up the support pins results in the symmetry of the left and right in the view above.
*1 Another restricted area is added when centering pin (option) is used.

PWBs clamping method
This is a method to use the PWB top surface as a reference to have both the PWB front and
rear ends each at the fixed and movable sides supported to the transport rails, then, to clamp
the PWBs.

* Standard： Manually adjusting method with your hand
* Option： Automatic PWB width adjusting method via a motor

4.7.6. Function correcting the PWB positions
Field of vision for recognizing the PWB reference marks
□6. 3 mm (camera’s field of vision for recognition).
Figure 6 Field of vision for recognizing the PWB reference marks
Window size for recognizing the PWB reference marks
This size can be changed within a maximum of 6.3 mm, subject to securing a clearance
between the recognition mark and its surrounding area.
Kinds of recognition marks and corrective method
- PWB reference mark
Two or three marks are located on a PWB to correct the entire PWB.
When a machine detects two PWB reference marks, it corrects the positioning, angle and
expansion/contraction of the entire PWB. When detecting three PWB reference marks,
it corrects the perpendicularity in the X and Y direction also.
- Component positioning marks
If a component such as an IC (QFP) needs to be placed on a board very precisely, two or
three marks set on a component itself are used to correct each component placement
position.
- Marks used to position the component area
Two marks (their positions can be set as you like) are to be provided to a group of
components placement positions, and they are used to correct each component
placement position in the group.
Note
：
The position is arbitrary, subject to not aligning three (3) reference makes,
if this is the case, on one (1) straight line. (It is recommended that the reference marks should
be made at the four (4) corners of the PWBs.
