Reference point
- Reference point designated by a mark. reference point differs from side view type
(hereinafter called as SV) and top view type (hereinafter called as TV) model, and x-shift
and y-shift of LED package will be measured and calculated based on this mark.

50um of processing error.)
2) Teaching method
① Teaching and setting mounting inspection
- Conduct non-mounting, damage, and turnover inspection through mounting inspection.
- Select color light, and select image type by changing R, G, B, and L to select the clearest
image type. Since LED has polarity, we check at polarity.
[Figure 5-243 Mounting inspection setting and preview image]
② Foreign material inspection (solder inspection) teaching and setting
- The purpose of foreign material inspection is to inspect foreign material on fluorescent
substance surface. For this purpose, we use solder inspection window.
- Select proper light type and image type to detect foreign material in Fluorescent substance
area of LED package. If foreign material appears in black, adjust color map to detect
foreign material.
- Select general inspection for inspection type.

- To detect foreign material, only fluorescent substance area is inspected. Therefore, set
electrode area as „Don‟t care region‟. If electrode of LED package appears, regard it as
„Don‟t care region‟.
- Check at pixel unit inspection, and enter allowable number of max white pixel for normal
criteria
