Solder amount inspection (advanced inspection) result
- Avg Lead Color (Min, Max):
Average value of lead color ratio
Calculated normal range of average value based on min color ratio – (%) and max
color ratio + (%) on lead tap
- Avg Shoulder Ratio:
Average value of color ratio of lead shoulder
Calculated normal range of average value based on shoulder color ratio ± (%) on
fillet tap
- Lead
No: No of inspection lead
Color: color matching ratio of inspection lead
Avg: average value of shoulder color ratio of other lead that excludes inspection
lead
- Fillet
Area: ratio of type fillet area of inspection lead fillet (%)
Blue: blue pixel ratio of inspection lead fillet (%)
Color: min color ratio – of inspection lead fillet (%)
Red: red pixel thickness of inspection lead fillet (%)

IC color result
- Pixel ratio inspection
Pixel ratio of color inspection area is displayed in each lead. If it is above normal
ratio, judge as good.
Normal ratio: the first value is value entered in pixel ratio. Min value to judge as
good.
- IC average ratio inspection
Pixel ratio of color inspection area is displayed in each lead. If it is within normal
ratio range, judge as good.
Normal ratio: average value and pixel ratio of lead, calculated by IC average ratio
inspection input value.
