S-type Algorithm - Body Mode (Classic)
1. Body Presence consists of 2D detection & 3D Detection.
2. 2D Classic Presence/Absence takes the average grey scale for the red lead boxes and subtracts the average grey scale for the green
boxes to give a presence score.
3. 3D Classic takes the inspected average lead height in the red box and compares it to the presence threshold pre set.
4. This is the recommended solution for detecting presence/absence for s-type, components.

1. Presence Thres
● Presence Thres for 2D
● Average grey scale for the red lead boxes subtracts the average grey scale
for the green boxes larger than the presence Thres Set consider pass.
2. Green Box Size
● To adjust the size for green boxes.
3. Green Box Offset
● To adjust the offset for green boxes

4. Presence Thres (um)
● Need to enable 3D mode.
● Inspected lead height higher than Presence Thres (um) to pass the
inspection.
5. Coplanarity
● Need to enable 3D Mode.
● Can adjust the location for the coplanarity ROI based on the predefined list.
● 2 modes: Corner & Cross
CoplanThres
Pass Fail
6. Coplan Thres (um)
● Fail when the difference between the 2 opposite ROI larger than the coplan
threshold.
Corner Cross
