1.2.10.1. Fix Camera Scale Calibration

The fix camera calibration must be performed before performing fiducial camera

offset calibration.

First, teach the fiducial mark on the upper surface of the fix camera and perform

calibration of the fix camera scale using the CNT20 nozzle.

 <3. Fix 1 Camera> button

This calibration is performed to calibrate the Scale (um/pixel), Rotation (deg)

and Position (mm) of the fix-camera.

In order to perform this calibration first, the R-Offset Calibration must be

performed in advance and the calibration-nozzle must be used. Use Hole #1 as

the ANC hole exclusively used for the calibration-nozzle.

The following is the procedure to calibrate the Fix Camera Scale;

1. If the <3. Fix1 Camera> button is clicked, the message “First, We must Put

all Nozzles From Heads on Manually. To Move down Z Axis, Click

[Next]” appears in the message box. Click the <Next> button to move

down the Z axis of the head in order to manually move all nozzles inserted

in the nozzle holder of the head.

2. Then, after the head assembly moves to the designated position, move all Z

axes down. At this time, remove all inserted nozzles manually

3. “Then the message “Next Attach the Calibration Tool to Head 1. Click

[Next] for Moving Down Head. After Moving, Attach the Tool to head

Manually” appears. Click the <Next> button after inserting the CNT20

nozzle at nozzle holder of Head #1 manually.

Cautions to be taken when inserting the CNT20 nozzle.

Insert the CNT20 nozzle by referring to the following figure.

<Direction Setup Pin of CNT20 nozzle > <Direction Setup Groove of Nozzle

Holder >

4. The message “Move To Center Position of [Fix1] Camera. To Move, Click

[Next]” appears in the message window. Click the <Next> button to move

The CNT20 nozzle must be inserted in

the nozzle-holder so that the direction-

setup pin of the CNT20 nozzle is suitable

for the direction-setup groove of nozzle-

holder. Otherwise, an error may occur.

Caution

the head assembly to the center of the fix-camera..

5. The message “Calibration is Prepared. To Calibrate, Click [Next]” appears

in the message box. At this time, click the <Light…> button and adjust the

brightness of the light in the ‘Light Control’ dialog box so that the fiducial

mark on the CNT20 nozzle that is seen in the ‘SMvision’ window can be

seen clearly. Then click the <Next> button..

6. The calibration is performed automatically. If it is completed, the

calibration result is displayed as shown in the following figure. Click the

<Update> button to apply the new calibration value.
