1.2.7 OCC parts identification
(1) Offset correction camera
The machine is equipped with a coaxial light and polarizing filter as the standard
devices. The camera detects a BOC mark and corrects the detected mark
automatically.
① OCC camera
② OCC lens
③ Illumination LED board
④ Mirror box
Figure 1.2.7.1
Adjusting the polarizing filter
1) Place a white ceramic board on the calibration block, then move the camera over
this board.
2) Loosen the screw to turn the filter holder to the right and left. When the screen
becomes brightest, fix the screw.

1.2.8 VCS parts identification
The VCS recognizes a component with the following devices: reflective/penetrative
lights, three-dimension movable light and coaxial light, then places on a board a
component such as a QFP, BGA, CSP and connector.
