B-type Algorithm - Joint

1. Solder Inspection

● Solder Inspection consists of 3 mode. Which are:

Difference between Terminal & Base

Terminal Reference:

Solder height qualification is based on the height (%) between lead

terminal & PCB surface

Base Reference:

Solder height qualification is based on the height (um) measured from

PCB surface.

● Solder Inspection consists of 3 mode. Which are:

2. Joint Grey Thres

● 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
