Patent number: 6300771Abstract: An electric inspection device impresses between a pair of terminals a current pulse train having a constant pitch, a constant pulse width and a constant current, and measures the resistance appearing between the terminals based on the voltage appearing between the terminals. The variation of the resistance measured for the current pulses is compared against a threshold. If there is any latent defect in the circuit, such as latent open-circuit or short-circuit failure resides which is not in effect at present, a large variation of resistance is observed.Type: GrantFiled: November 23, 1998Date of Patent: October 9, 2001Assignee: NEC CorporationInventor: Tsutomu Goshima
