14.4. Position Correction

After the placement test, any error related to the placement position shall be solved

through position calibration.

14.4.1. Specific Placement Point Position Error

Even though the components were placed on the PCB normally, placement position error

may occur at one specific point and it may have been caused by the incorrect coordinate

of the corresponding position.

Checking position on the PCB 

Move the “Move Camera” to the actual position on the PCB corresponding to the

coordinate of the placement point where placement position error has occurred, and

check the placement position through the vision monitor.

Changing placement position 



If the corresponding position deviates off the actual placement center, change the

coordinate of the placement position once again by teaching the placement point.

14.4.2. Movement of Specific Component Placement Position

When placing the specific component, if the position where the actual component is

placed is deviated from the placement position in the same pattern, the component profile

may have a problem.

Component profile change

Check Align Data in the corresponding component profile. Check if the size and

thickness of the actual component has been entered incorrectly. If so, change the error.

14.4.3. Change of Placement Position on the Entire Block or Some Part of the

Block

If placement position is moved for all components placed on the PCB in the same form,

an error may occur in the PCB origin, initial theta or fiducial mark position.

PCB Origin Error 

If the coordinate of the PCB origin is setup incorrectly, the coordinates of all

placement points are likewise setup differently from the actual positions.

Move the “Move Camera” to the PCB Origin position set in the “Board” dialog box to

check for any error and if there is, change the coordinate.

Initial Theta Error 



If all the components placed on the PCB are being rotated in the same direction, it is

because the PCB is not parallel with the coordinate system of the machine due to

some problem with the PCB.

Teach the Initial Theta of the PCB to check if its value is zero (0), otherwise, change

the PCB and perform the placement test again.

Fiducial Mark Position Error

If there is even a slight error in the coordinate of the fiducial mark center, it causes

slight error to the coordinate of the placement position.
