Step Procedure (Negative Test)

Negative test is used to rotate all components to 180 degree and

reinspect the program. Therefore, the rotated component should

show "failed as polarity" to prove that the program has detected

the polarity defect. There are four steps to complete the

orientation negative test which are:

● Run "Negative Test" under inspect button.

● Analysis negative test inspection result.

● Fine tune escapee component.

● Ensure no escapee component in final result.
