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.

Obtain correct size, center coordinate and accurate tuning of the fiducial mark.

Array Setup Error 

Refers to the placement position error that occurred to the components placed on the

specific block in the case of the Array PCB.

An error may occur due to an incorrect array coordinate. Move the “Move Camera”

to the actual Array coordinate and check for the error through the vision monitor,

changing the coordinate if any error is found.

Move and place the machine at the corresponding location using the teaching box.

Teach the origin point of the Array PCB 1. Pressing the “Enter” key after teaching will

display the following screen.

Pt.

Teach the origin point of the Array PCB that is at the position that can determine the

offset. Pressing the “Enter” key after teaching will display the following screen.

If the “Enter” key is pressed, the teaching of the Array PCB offset is completed.

14.4.4. Placement Error of the Component Placed Using Specific Head

If a placement error occurs only to the component placed using a specific head, it may

have occurred due to a problem with the head.
