2) Vision centering
When you select the “Centering” tab, the following screen appears.
① Nozzle No.
② Vacuum level
Set these items as described in “1) Laser centering.”

③ Recog. Offset
The system moves the pick-up center position of a component (normally the center of a
component) to the center position of the VCS to center the component with the VCS.
However, since the system cannot pick up the center of a component such as an MCM
(Multi Chip Module) and the component position may be located outside the VCS field view
range, it may not be able to center the component with the VCS. In this case, enter offset
values (a, b) as shown below to ensure normal recognition.

④ Gripper nozzle data
Set this item as described in “1) Laser centering.”
⑤ S-VCS
Specify whether to recognize a component with an S-VCS or not.

⑥ Multi-recognition
This function is described as follows. As the VCS with a field-of-view of 54 mm captures
images of up to four components and recognizes them, the XY-axis movement distance and
the number of image capturing times during VCS recognition operation are minimized.
Additionally, as the light control is optimized, the exposure time of the VCS camera is
shortened to a level that is 1/6 or less of the conventional exposure time and the placement
tact of the vision recognition is improved from the conventional S-VCS.
The S-VCS can perform the recognition only with the same light within one cycle, but the
multi-recognition can perform the recognition with different light settings using nozzles 1 to 4
and nozzles 5 to 8.
The following describes the component data conditions for the multi-recognition.
1. Vision components with a component size of □ 3 mm to □ 14 mm (Pickup offset is
considered.)
2. Boss height 0.00 mm
3. Recognition center offset (0.00 mm, 0.00 mm)
4. VCS selection is a field-of-view of 54 mm.
5. Lights other than transmission light
6. VCS focus height is 0.00 mm.
7. Batch recognition
8. The direction of a BGA component is not inspected.
When the conditions shown above are satisfied, "Used" or "Not used" can be set.

Not used
Does not perform the multi-recognition even when there are
components applicable to the multi-recognition.
