1. Joint Logic control
● OR Logic: Either 2D or 3D pass will consider as pass.
● AND Logic: 2D and 3D must be passed to consider as pass.
2. Fillet Gradient Thres
● To enable Fillet Gradient Inspection.
● Unit in degree.
Bumpy Detection
Slope Detection
Length Detection
3. Fillet Image Plane
● These are the types of 2D Lighting. Select the one with having
highest contrast among interested inspection region and the
background.
● Usually choose angle 2+3

6. Fillet Solder Length (%) & Fillet Width (%)
● The overall pass criteria depends on:
a. Solder Width (%) > Solder Width Thres (%)
b. Solder Length (%) > Solder Length Thres (%)
c. Both solder Length and Solder Width must pass.
● Pass Criteria for single pixel:
a. Measured Grayscale < Joint Grey Thres
b. Solder Height (%) > Joint Height Thres (%).
c. OR Relation between 2D and 3D as pass criteria for single pixel
