[Figure 5-231 Position parameter for cold solder detection]
⑨ Details
- If red ratio of Center Rect is above reference value, decide whether to judge it as lifted or
not.
- Divided area from electrode end to pad end into 4. If the position of red area extracted
from pad area exits in the first area that is close to electrode, judge as lifted. Besides that,
judge as good.
- When solder is large and thin red due to light effect on a little bit big chip above chip 1005,
this algorithm is displayed in similar shape with lifted by the color map. However, this is set
to use the characteristic that it displayed away from electrode.
Chip shift inspection
- Shift Range is max length for Shift from electrode end to pad end viewing from the length
direction of chip. measure distance from electrode end to pad end during inspection.
- If measurement data is larger than Shift Range setting value, judge as defect. In general,
set Shift Range value as long as pad length.

5.3.14 Teaching by using side viewer
Use this option to inspect component of which component height is high and solder area is not
clear.
Teaching method
① Click desired inspection window button among general-purpose/exclusive inspection
windows.
② Change camera using camera selection button and conduct teaching using same method for
main camera.

[Figure 5-235 Teaching example using side viewer]
As shown in [Figure5-147], even teaching for solder area that is not clearly displayed by main
camera can be easily done if side cameras are used and more correct inspection can be
conducted.
Since the frame of side cameras are fixed frames, if camera is different even for teaching at the
same position, „Group component‟ can‟t be done.
③ If component that completed teaching is selected in the frame, click <All> button after
activating of <All> button among camera selection buttons to display images imaged by all
cameras as shown in [Figure5-148].
