2. 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)

3. Refine Location

● Tick this to help to locate the fillet.

● Recommend to on this.

4. Correlation Channel

● Refers to the image used for location

5. Lead Tip Search

● Usually set to standard

6. Revert 4.12
