(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 Yesradio button in the Checkfield, 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.

(2) Measure PWB Surface Height
This setting item allows the system to measure the height of the board surface at the
component placement position to correct the Z-coordinate of the component
placement position.
The center (one point) of the component placement position is to be measured.
According to the measurement result, enter the threshold value for determining
whether the board warps or not in the Thresholdfield.
When the measurement result is within the range of Threshold valueto Threshold
value,the system determines that a component can be placed on the board.
To measure a position other than the component placement position, enter the Offset
X” and Offset Yfields.
(3) Check Component Height after place
This setting item allows the system to measure the heights of four corners of a
component such as one having a boss after it is placed on a board, and check to see
if the placed component is tilted or not.
When the measurement result is within the range of Threshold valueto Threshold
value,the system determines that the component has been placed on the board
normally.
If it exceeds this range, the current production stops temporarily.
Setting item
Description
Check
Specify whether to check or not by selecting the corresponding radio button.
No. of Samples
Specify how many positions to be checked within the range of 2 to 4.
Threshold
Specify a value for determining whether a placed component is tilted or not.
Offset X, Y
Specify where to check by entering the offset from the component placement
position. From the top, specify the measurement positions 1, 2, 3 and 4.
The relation between the measurement offset positions and the check positions is
shown in the figure below.
