Solder Height Thres (um)
● It’s used to set the minimum height requirement for the solder joint.
● May vary when component body lifted happened.

1. Solder Profile
● Using 2D (Grayscale) and 3D(Height)
● Include Bumpy solder Inspection as fail criteria.
● 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
● 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.
