 Select both of IC color and pixel ratios to activate this.

 Min value of normal range is average value – pixel ratio, and max value is average

value + IC average ratio inspection+ (%). (For example, when average value = 50,

pixel ratio=10, IC average ratio inspection+ (%) = 20, normal range min value = 50

– 10 = 45, and normal range max value = 50 + 20 = 70.)

 Inspection result (common)

- Number Of Lead: number of lead

- Number Of Gap: the number between lead and lead

- Average Lead Width: average width of lead

- Average Gap Width: average width between lead and lead

- Average Pitch: average distance between lead center

- Average Lead Tip Size: average of lead tip width (value display during solder amount

inspection)

- Lead Count Direction: direction to allot No of each lead

[Figure 5-153 inspection result detail (common)]

 IC Bridge inspection result

- Lead Width: width of lead

- Gap: width between lead and lead

- Pitch: distance between lead center
