Restrictions
1. The size of a component should be able to be recognized at a time, and the component
should satisfy the conditions for recognition within the measurement field view.
2. Only electrodes whose diameter is the same are arranged in a reticular pattern, and look
brighter sufficiently than the background.
3. All parts that look bright except for electrodes are specified as an eliminated area.

Measured
parameters
1. Number of extended array groups
2. Number of balls in an extended array group
3. XY coordinates of a ball in an extended array group (for all balls of a group)
4. Diameter of a ball in an extended array group
* The system measures the items 2, 3 and 4 per group.
Parameters not

Outer dimensions of a component The input value is used.
Element data type Ball components
Data format definition Extended array data format
Extended array group name Numbered in ascending order from a default number.
Element type Ball, land
Light Blue side light (for a ball)
Reflective LGA light (for a land)
Field of view 54mm27mm10mm
Others Default parameters applied when the Component
data was created
Restrictions
1. The size of a component should be able to be recognized at a time, and the component
should satisfy the conditions for recognition within the respective measurement field view.
2. Only electrodes whose diameter is the same should look bright with good contrast in the
teaching window.
3. The maximum number of groups that can be created is 20, and the maximum number of
elements in one group is 256. However, if the number of elements in the teaching window
exceeds 256, the group is divided. Therefore, the number of teaching windows you can
set may be limited to less than 20.
4. Since the data is created with teaching operation, the center of a component may be offset
by approximately one pixel at worst. A theta coordinate may be offset in the same
manner.

3) Operations during teaching of a component
Head to be used for pickup
Regarding selection of a head to be used for pickup, the head is automatically selected.
The existing mounted nozzle has priority so that the frequency of nozzle replacement
may be reduced.
A different head may be used for each measurement in some nozzle mounting
conditions.
When the MNVC function is effective and inspection components are assigned to the
left head, it is possible to select a head for inspection.
Return of components after inspection
After inspection, components may be returned to the original position or discarded.
This depends on the packaging style as shown in the following table.
For discarding, components are discarded according to the "Component reject to"
setting in the component data.
Since a component whose size is 1 mm or less may be placed on its side or turned
upside down when it is returned, the system displays the message so that you can
select how to handle it.

*1 The system displays the message that asks you whether to return a component or
discard it. The system displays this message before it starts continuous measurement
of components in Continuous Measurement mode.
Selection of component supply unit for pickup
If two or more component supply units are assigned to the same type of component in Pick
data, you can change the supply unit. A component starts being picked up based on the
data you entered first by default.
Change of pick coordinates
In case pickup cannot be performed satisfactorily, change the pick coordinates by manual
input or coordinate teaching.
Manual pickup
When there is no pickup data, a component can be attached manually onto the nozzle. In
this case, the pick coordinates cannot be input. The feeder cannot be operated either.

(1) Component teaching operation
1) Component teaching setting
When you select the [Meas/Insp] command from the menu, and then the [Vision teaching]
command, the following screen appears.
Menu item Overview
Component under inspection
The contents of a component required for component teaching are
displayed.
Pick position
The contents of the pickup position to pick up a component are displayed.
It is also possible to change the pick position to the previous component or
next component. When there are no pick data at manual pickup or in the
case of MTC, each item is put to a non-display status, so that pick position
change, feed knock, and teaching are disabled.
<FEED> button
This button feeds a component.
Measure item
Select an item for measurement. At the default, all the measurable items
are selected. The measurement items may be put to a gray-out status
depending on the component type, and cannot be selected.
If no item is selected, measurement is not performed.
VCS recognition field
Specify the VCS type to be measured.
Electrode type
Specify the electrode type of the component to be measured.
<MEAS.> button
This button is used to display the measurement execution screen.
<Prev. component> button
This button displays an alternative component.
<Next component> button
This button displays an alternative component.
<Exit> button
This button is used to go back to the original screen after completing
teaching settings.
