S-type Algorithm - Location Mode (Vector)

5. Extra Reducer

● Extra reducer omits corners of the search area from inspection that may

be brighter than the leads and results in the leads locating incorrectly.

● This is useful for components with leads on 4 sides, where there are bright

via holes, text or components at the corner of the inspected search area,

which are causing the component to locate incorrectly.

● Units: microns

● Recommended value: 0

8. Edge Strength

● Parameter changes the strength of transition from bright to dark required

for it to be called an edge. It searches out from the center of a component

for the leads, picking up on the edges. Default value is 0

7. Used Inside Edges

● It searches out from the center of a component for the leads, picking up

on the edges.

9. Image Plane

● Select the image plane that having best contrast between the component

and the background.

10. Offset Thres

● Unit in micron (um)

11. Skew Thres

● Unit in degree.
