Open Localization with LIT

Abstract

Abstract This paper discusses a method to observe open traces with the LIT. An overview is given of FA techniques capable of localizing high Ohmic fails. It is discussed how a wire can be made observable with LIT by injecting an AM modulated RF carrier signal. The electrical stimulus is described that excites the device and triggers the LIT. Results that demonstrate the capability of the technique are presented for several devices and the findings are evaluated.
