(6) Vacuum time adjust
Specify whether to adjust the vacuum time or not.
When you select the “Yes” radio button in the “Adjust” field, enter a value in each of
the “Vacuum stop timing” field, the “Vacuum stop correction value” field, the “Blow
starting timing” field, the “Blow continuing timing” field and the “Vacuum OFF wait
time” field in unit of ms.
When you use a gripper nozzle, the system does not make any adjustment when it
places a component on a board.
(7) Trial
In the same manner as the setting on the “Placement” data screen, on the
“Production” (Trial mode) screen the system places only components for which the
“Trial” field is set to “Yes.”
When you select “Yes” in the “Trial” field on this “Component” data screen, the system
sets all placement positions of a component by one operation.
If you want to specify whether to perform a trial operation on each component
placement position, use the “Placement” data screen.
(8) Release check
This check is intended for laser centering components. This function checks
whether any component is attached to the nozzle after completion of a placing
operation.
It takes some time for the system to check that a component is released (since the
system checks it while it is put in the pause state). Normally select the “No” radio
button.
(9) Component skip
When you select “Yes” for this “Component skip” field, the system skips the
corresponding component during production and does not place it on a board.
The placement data record that uses a component whose “Component skip” field is
set to “Yes” is not used for production, and is not listed on the “Not placed” list.
When you load the component information form the database, this “Component
skip” field is set to “No.”

4.1.4.2.6 Inspection
Specify the fields “Tombstone,” “SOT Angle,” “Pick Position Detection,” “Component
verification,” and “Dimension check.”
The field “SOT Angle” is optional.
(1) Tombstone
Specify whether to check that a component stands on its side (“Tombstone” error).
Normally, we recommend that you select the “Yes” radio button for a 3216 chip
component or smaller ones. Therefore, when you select a “Chip” as the
“Component type,” the system automatically selects the “Yes” radio button.
“Tolerance”: The system automatically enters a value calculated from the component
height you entered to this field..
(2) SOT Angle (option)
This specifies whether to perform or not 3-terminal lead SOT direction inspection.
The SOT direction inspection of the first component before production and after “no
components” can be performed.
Perform this check mainly to check that a correct component is not set.
This function can be selected only when the component type is SOT.
(3) Pick Position Detection
This function detects whether the center of a component is shifted by a value more
than that set in the “Tolerance” field when viewed from the center of the nozzle.
This function is available only if the packaging style is a tape feeder. Otherwise, this
function is disabled. Select the “Yes” radio button for the desired component, and
enter the value in the “Tolerance” field as the judgment value.
The range of a value you can enter in this field is from 0 to the length of a component (or
width of a component if the component supply angle is 90º or 270º).
When you select the “Yes” radio button, the default value to be set in the “To lerance”
field is calculated with the expression shown below:
Length (or width) of a component ÷ 2 × (set value/100)
The “set value” is set in the “Environment setting” screen of the Program Editor. The
default is 50 (%).

(4) Component verification
* JX-350 is not applicable to the component verification.
(5) Dimension check
Specify whether to check a dimension of a component, and enter the standard size
and the size used for judgment if the system checks.
If you check the “Yes” radio button in the “Check” field, the system checks the width
and length of a component when centered, and an error occurs if these dimensions
exceeds the upper/lower limits and the system judges that the component is
irregularly-shaped.
Use this check function mainly to check that a component of the specified size is not
set.
The system performs this check when it centers a component during production.
The component to be judged is laser centering component.
4.1.4.2.7 Inspection 2
On this tab, you can make settings of the coplanarity check data (“Coplanarity check”),
those of measurement of the board surface height on which a component is placed
(“Measure PWB Surface Height”) and those of measurement of the component height
after it is placed on a board (“Check Component Height after place”).
(1) Coplanarity inspection data
* JX-350 is not applicable to the coplanarity inspection data.
