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.

2. Joint Interpolate

● Enable this to include decimal place in pixel calculation.

● Value display in integer with converted from pixel decimal

calculation.

3. Joint size

● To adjust the joint inspection area.

● Yellow boxes shown below.

4. Joint Offset

● To adjust the joint boxes away from the component body.

5. Joint Plane

● Select the one that having best contrast among the Joint Area

and background.

● Good Joint having Dark in colour.

● Default set to 160.

● Fail Criteria: Grey scale measured > Threshold set
