In general situations, the fiducial mark is not measured individually and the
coordinates of the fiducial mark are created after setting the PCB on the conveyor.
Input the approximate size (by visual judgment) and check the image mark deviation
between the actual mark and the image mark in the data through the SMVision
window to perform recorrection.
In this case also, more accurate correction can be made by performing measurement
through tuning. This function is executed until the actually measured new data
becomes equal to the inputted data.
<Outline/Real> button
Shows the image seen through the Vision in real display to which threshold is not
applied, or in the image (Binary) to which threshold is applied as recognized by MMI.
<Test> button
By using the registered mark information, tests the fiducial mark.. The accuracy of the
registered mark data can be verified. When the test is successful, the following
message box is displayed.
<Scan> button
Executes a scan test on the set fiducial mark. Mark recognition is performed to
minimize the teaching offset for the center points (2 points) of the fiducial mark.
Move the fiducial camera to the position of the set coordinate and recognize the mark.
After recognition of the mark, the offset is indicated as shown in the following figure.
When it is desired to compensate the offset, select “Yes”.
When placing the IC part whose lead pitch is 0.5, use this function to perform
compensation for the fiducial mark.
