6) Parameter of [chip color inspection] window
Optimization
After completing teaching, click optimization button. Chip type, chip body tap (electrode minor
axis length, electrode major axis length, pad offset, binarization) and pad inspection tap (size of
lifted inspection area, chip offset) information will be automatically calculated and allotted using
the result.
7) Parameter of [chip body] tap
[chip body] tap is to extract pad offset and electrode. This plays the role of calculating optimum
chip inspection parameter.
[Figure 5-218 parameter window of chip body tap]
Pad range
① Pad offset
- Set offset value as long as pad length at both ends in chip color inspection window.
designate range for electrode extraction and area to inspect non-mounting.

- If normal separation of electrode is not done because all part of chip became one due to
binarization or too high binarization value must be used for electrode separation, adjust
pad offset position close to chip electrode to limit electrode size.
- Sometimes, locate it close electrode to reduce false defect of non-mounting. However, if
window is warped, yellow dotted line will be set in electrode area. Hence, do not set it too
closely to electrode.

[Figure 5-220 Example of chip of which electrode is not separated from chip body]
Binarization
- Click „optimize‟ button to conduct optimization after initial teaching, and check for good
separation of electrode in preview. If electrode and chip body is not separated, set proper
value for binarization boundary value for good separation of electrode and chip body part
checking preview.
- After adjusting binarization value, make sure to click optimization button to refresh chip
information (electrode size, electrode distance).
- Adjust parameter on chip body tap before optimization after teaching, and click
optimization button to ignore chip body parameter set by operator. Hence, make sure to
firstly conduct optimization before parameter adjustment after teaching.
Noise removal
① Area
- This is used to extract only electrode by removing white noise besides electrode. Enter
size of white noise to be removed in pixel unit.
② Electrode edit width
