(2) Each operation to be done when the system is checking the speed
1) Returning a component after the check
After checking the speed, the system returns a component to its original position or discards
it. Which operation is to be done varies depending on the packaging style as shown in the
table below. The system discards a component to a place specified with the setting of the
“Compo reject to” field of the Component data screen. If you select “Protect” in this field,
the system discards a component according to this setting. Since a component whose size
is 1 mm or less may stand on its side or may be turned over when it is returned, the system
displays the question dialog box that allows you to select how to handle the component.

*1 The system displays the message to ask you whether to return or discard a component.
*2 When you select the “IC collection belt” or “Protect” for the menu item “Component reject
to,” the system operates according to the corresponding setting.
2) Selecting a feeder from which the system picks up a component
If two or more feeders are specified for the same component type (in Pick data), the system
starts picking up a component based on the data entered first. You can change the feeder
to be used intentionally also.
3) Manual pick-up of a component
If there is no Pick data created, you can attach a component onto a nozzle manually also.
In such a case, you cannot enter any pick-up coordinates. You cannot operate a feeder
either.
If you attach a component to the nozzle manually, the system cannot discard it if the length
of the shorter side of its outer dimensions exceeds 33.5 mm. Therefore, the system moves
the component to the protection position after measuring it.

4.5.7.6 Vision teaching
This function attaches on the head a component actually used for production, and measures a
lead of lead component (general-purpose vision) and a ball of a ball component
(general-purpose vision component, BGA or FBGA).
When you open the cover to, for example, pick up a component
manually, make sure that any operation of the machine will not
cause any injuries.
Be careful so that your hand or cloth cannot be hooked over the
feeder bank or you cannot bang your head against the cover.

2) Conditions for teaching a component
① BGA and FBGA
Contrast All balls-PWB or All land (“Out-PWB,” “Out-Ceramic” and “All balls-Ceramic” are not available.)
Base Style Standard and Mark overspill type 1
Ball Pattern User pattern

parameters
Vision recognition
Pitch (vertical, horizontal)
Diameter
Number of rows (vertical, horizontal)
Base style
Arrangement pattern (user pattern)
Others
Component height
Vacuum pressure
Parameters not
to be measured
Outer dimensions
Vision control data
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.”
② General-purpose vision component, ball component types (Extended array)
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
to be measured
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 54mm、27mm、10mm
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.
