Abstract

PURPOSE:To improve reliability in measuring the electric characteristics by providing two or more lands for measuring probes at a terminal of a circuit to be measured. CONSTITUTION:In the conventional method, if any one of several probes 1 fails to conduct, the reliability of the entire measuring system is lost. In the measuring method of the present invention, however, the reliability of the entire measuring system can be maintained unless all the probes arranged on the same conductor pattern fail to conduct simultaneously. The reliability Rk<n> of the measuring system is expressed by an equation Rk<n>=[1-(1-r)<k>]<n>, where (n) is the number of terminals, K is the number of the measuring probes per each terminal, and r is the reliability of each probe. In the case the reliability of the probes is high, two probes on the same terminal are sufficient.
