Abstract

This paper presents a theory of the superposition of two signal componentsformed during the inspection of printed circuit board (PCB) by an eddy-current testing probe composed of a meander-exciting coil and a solenoid pick-up coil. Proportion of these two components effects the amplitude and thc phase of the output signal. Characteristic changes of the phase characteristic, obtained from calculations and observed during the real,inspection of PCB, are explained.
