V. QUICK GUIDE TO CALIBRATION OF BGA/CSP-3500

IS YOUR PICTURE CORRECT?

Note: This should be done with a PCB in the board holder

What to check:

• Is the camera mounted so the video image is straight?

If not, rotate the camera.

• Is the color right in the picture?

If not, check lighting, aperture of lens.

Mirror Adjustment:

• Can you cross the split field to produce a single image at full magnification?

If not, using the 4 mirror adjustment screws and Allen key, align until you get a single image.

• When fully zoomed out, is there a shadow across the bottom of the screen?

If yes, check for fluorescent lighting above (in room), turn off if possible.

ARE YOU IN CALIBRATION?

Note: This should be done with the Calibration Plates in the Board holder. The medium vacuum cup should

be installed fully on, with the fine Z-Height adjusted down then turned back through 180° (Half a turn).

What to Set-up:

• Is the image of the vacuum cup central on the screen?

If not, use the 2 knurled screws to center it on the screen. Align with the image of the lower

calibration plate and magnify the circle to fill the screen. Place the second calibration plate

on top and lift using the vacuum pick up. Adjust the lights so that both top and bottom image

can be clearly seen.
