Electrical Characteristics Test

 

This procedure identifies and segregates the good and bad devices. The bad devices refer to those that failed the electrical criteria. A series of electrical stimulation is administered to the device under test (DUT) and its response is measured. For every set of electrical stimuli, the measured response is compared to the expected response, which is usually defined in terms of a lower

 

and an upper limit.Any DUT that exhibits a response outside of the expected range of response is considered a failure. The test program or test software controls the testing process executed by the tester.
