Open Lead Detection Based on Logical Change Caused by AC Voltage Signal Stimulus

چکیده
Abstract: In this paper, we propose a new test method for detecting an open lead which occurs when an IC is mounted on a printed circuit board. In the method, an open lead is detected by observing output logical change of an open lead detector. Since the test method is a vectorless test one, test generation and test input application are not needed. Testability of the test method is examined by some experiments. The results show that open leads of SSIs and LSIs will be detected by the method.

متن کاملTest Circuit for Vectorless Open Lead Detection of CMOS ICs
In this paper, a test circuit for a test method is proposed, with which open leads of CMOS logic ICs are detected without generating test input vectors. Open leads are detected by means of supply current of the test circuit that flows when an AC voltage signal is provided to targeted leads with test probes as a stimulus. It is examined by some experiments whether open leads will be detected wit...
متن کاملAlleviating the Small-Signal Oscillations of the SMIB Power System with the TLBO–FPSS and SSSC Robust Controller
Power systems are subjected to small–signal oscillations that can be caused by sudden change in the value of large loads. To avoid the dangers of these oscillations, the Power System Stabilizers (PSSs) are used. When the PSSs can not be effective enough, installation of the Thyristor–based compensators to increase the oscillations damping is a suitable method. In this paper, a Static Synchronou...

A new very simple single phase ac-ac voltage regulator based on LC network is proposed here that compensates wide range supply voltage variations. This has the capability of both buck and boost the input source voltage level without any change of phase angle. The number of components used in the converter circuit is minimum and smooth output waveform can be achieved without any additional filte...
