S-type Algorithm - Location Mode (Vector)

100

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.

S-type Algorithm - Location Mode (Correlation)

102

1. Lateral Location

● For Post Reflow, Tick this.

● For Pre Reflow, untick this.

● This can assist during joint inspection in location of the joints which having nice toe

fillets.

● There are occurrences when it does not correctly locate. (Bright Pad & Wide pads)

2. Refine Location

● Tick this to help to locate the fillet.

● Recommend to on this.

3. Correlation Channel

● Refers to the image used for location.

4. Image Plane

● Refers to the image used for presence/absence

5. Offset Thres

6. Skew Thres

● 10 = 1 deg
