Lead Ringer - Types of Ringer Tests

2. Pad Solder Shape Differs (Pad anchor)

• Inspection area: Pad Area

• Anchor set to (Lock to Search Area (CAD)" anchor)

• Image Plane: max(Angle 1,Angle 3)

• Compare each lead with its neighbours (per row comparison), with invert check (invert the results if most of the

leads of the row are defects).

3. Shoulder Bend Differs

• Anchor set to (Shoulder anchor)

• Image Plane: Angle 1

• Software measure the mean intensity of the pixels contained within the ROI.Compare each lead with its

neighbours (per row comparison), with invert check (invert the results if most of the leads of the row are defects).

• Inspection area: Shoulder Area

• If the lead is lifted (heavily) or bent, the lead will be visibly deformed: the shoulder will appear brighter in the

current region of interest.

4. Toe Sticks Out Gap

• Anchor set to (Lead Tip anchor)

• Image Plane: Angle 1

• Software measure the mean intensity of the pixels contained within the ROI.Compare each lead to a preset

threshold.

• Inspection area: Lead Tip Area

• If the lead is bent, then the lead tip will move forward, making the region of interest appear brighter.
