(4) Pick Condition
Pick conditions are setting items for pickup and the default values are applied. Accordingly,
they do not need to be changed. If pickup cannot be performed in the default value status,
change the settings.
CAUTION
If you change any of the basic settings after changing any value on the
“Pick Condition” tab, some values are reset to their defaults on the “Pick
Condition” tab.
1) Picking stroke:
Specify the distance for pushing a component during component pick-up.
If you set “0” here, the nozzle may not reach a component and may not pick up the
component, or a chip rise error may occur due to the variation of component heights. In
such a case, enter the larger value (that is, by entering a positive value) so that the nozzle
can reach a component.
The initial value is “0.2 mm” (0 mm for a 0603 or 0402 component).
2) Retry:
Set the number of times the system will pick up a component again if a component pick-up
error occurs during production.
If a retry over error occurs during PWB production, the signal light flashes in yellow to notify
you of the error.

3) Picking offset X, Y
If you want to shift the component pick-up position from the center of a component because
the machine cannot pick the center of the component or for any other reason, set the
“Picking offset X, Y.” Set the distance from the center of a component to the component
pick-up coordinates to be applied when the component is picked up in the “X” and “Y” fields
of the “Picking offset” menu item. Each value is added to or subtracted from the initial
value of the “X” coordinate and that of “Y” coordinate automatically calculated when you
create Pick data.
Since the settings of the “Picking offset X, Y” are to be used to decide the recognition
window for recognizing a component or to check a component pick-up position error, it is
recommended to set them if the center of the component is different from the component
pick-up position.
4) Picking offset Z
Specify how much to push the tip of the nozzle from the pick-up height when a component is
picked up. This value is used to automatically calculate the “Z” coordinate of the “Pick
position” of the Pick data. If you change the value set in the “Z” coordinate of the “Picking
offset” even though the pick-up coordinates are already completed, the system does not
calculate the pick-up coordinates again. When you change the setting of the menu item
“Side” of the Pick data corresponding to the changed Component data to “AUTO” and
specify the pick-up position again, the system calculates the pick-up coordinates again, and
changes the value in the “Z” field also.
5) Pick-up coordinate offset
If you have to shift the component pick-up position from the default position X, Y in order to
pick up the center of a component, set the “Pick-up coordinate offset (X, Y).” The function
of a coordinate Z is not different from that of the “Picking offset Z.” Enter a correction value
to be applied to each initial value that is automatically calculated when Pick data is created.
Set the distance from the pick-up coordinates calculated automatically to the center of a
component and the height in the “Pick-up coordinate offset” fields. Each value you set in
these fields are added or subtracted to/from the corresponding initial value automatically
calculated when Pick data is created. Set these fields if any of the initial values of the
component pick-up coordinates is shifted from the center of a component or the component
pick-up height.
When you set both the “Picking offset” and the “Pick-up coordinate offset,” the total of
these offsets is reflected in automatic calculation of the pick-up coordinates as a value to
be added or subtracted.

6) Speed
Select the speed at which the Z-axis moves when a component is picked up.
When you select load control, the pick descent speed is changed to "FC speed."
7) Auto correct pick
For tape components to be centered with laser, this function corrects a pickup mis-position
automatically based on the recognition result.
The corrected position is entered to the coordinates field of the component pick-up position
on the “Pick” data screen when you select the <Yes> button.
CAUTION
For a component whose center is not picked up, select “No” as the
“Auto correct pick” (select “No” also if you enter the “Picking offset”).
The system corrects the component pick-up position without causing the simultaneous
pick-up to be disordered by correcting the pitch in Y direction when an electric feeder is
used.
8) Auto teaching
This is the function for automatically measuring the center of a component when the system
tracks the component pick-up position.
For square chips 0402 to 3216 whose packaging style is an 8-mm paper tape or 8-mm
emboss tape, you can set [Yes].
However, the default setting is [No] as the auto teaching cannot be performed in accordance
with the color or shape when the packing style is an emboss tape.
9) Vacuum time adjustment
Specify whether to adjust the vacuum time or not.
When you press the <Setting> button, the following screen appears.
When you select the <Yes> button for the menu item “Adjust,” you can enter an adjustment
value for each item of “Vacuum starting timing,” “Vacuum starting correction value” and
“Vacuum stability waiting time” in milliseconds.
