2. Extract

● If “Compare To” is set to “Threshold”, There are 2 Extract Option as follow:

● Mean Intensity: The mean intensity of the pixels contained in the box is measured and

compared with the threshold for each lead of the row.

● Curvature: the curvature feature is calculated for the current box and compared with the

threshold for each lead of the row

4. Anchor Point

● The region of inspection.

● The anchor points available in the Lead Ringer algorithm are as follow:

➔ Lead Tip anchor: (result of the lead location algorithm)

➔ Shoulder anchor: (result of the lead location algorithm)

➔ Lead Tip (Lock to Cad) anchor: (result of the geometry settings entered by the user, taking into

account the component position, number of leads, pitch, lead length, ...)

➔ Pad End (Lock to Pad) anchor: (result of the Pad Locator algorithm)

➔ Search Area End (Lock to Cad) anchor (similar as Lead Tip (Lock to Cad), but the point is

locked to the search area instead of being at lead tip)

➔ Green Box Inner Edge anchor: (result of lead location algorithm)
