Lead Ringer - Parameter Description

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)

5. Offset Along

● To adjust the offset of ROI from the anchor point set.

6. Size Along

● To adjust the size of ROI (Y-Direction).

7. Size Across

● To adjust the size of ROI (X-Direction).

8. Centre Gap

● Enables the user to separate the ringer box into two for each lead.

● The RInger comparison will be carried on the resulting sum of the values with those two boxes.

● The Centre Gap option is used when a change appears on the sides of the lead/solder areas, or when an

unwanted reflection is present in the middle of the lead width.

● Note that inserting a centre gap different from zero should lead to a revision of the current thresholds.
