Joint Inspection Algorithm

CR Type Algorithm - Joint

1. Joint Inspection

● Tick this to enable joint Inspection

2. 3D Mode

● Consists of 4 mode.

● The main differences between the 2D only and 3D for joint

inspection are the height while solder profile has additional

feature to check slope of joint.

CR Type Algorithm - Joint (2D Only)

1. Fill Pad

● Fill pads is used when the pads are very flat, and hence when

lighted with the default lighting do not come up bright. This can

cause insufficient pads to pass.

● Fill pads would be useful for the 3rd joint down on this image. It

is very dull as it is low on solder and the pads are dull. As it is

dull, the red image may not have many bright pixels and there

may not be sufficient to do the full inspection.

● However with fill pads, it takes this image with Angle 3 also. This

increases the brightness. This only changes the lighting for the

joint, hence there is no visible change on the image. There is no

increase in cycle time.
