Title: Apparatus for inspecting printed circuit board
Inventor: FUJISAWA MASAYUKI
IPC: G01R31/00
Filed: 1987-01-29
Abstract: PURPOSE:To perform accurate inspection by removing the effect of the residual charge, by a method wherein a measuring voltage signal and a negative-phase voltage signal are applied to one end of a standard board and one end of a board to be measured through probes and, after the response signals to both signals are detected, the input terminal of a detector is grounded. CONSTITUTION:The measuring voltage signal Vref emitted from a signal source E is applied to the reference part in a standard board Bs through the in-phase amplifier A and a probe P3 and the negative-phase voltage signal reversal Vref from a negative-phase amplifier reversal A is applied to the part to be inspected in a board Bx to be measured through a probe P4. When the impedances Zs, Zx of the reference part and the part to be inspected are Zx>Zs, the response signal Vo taken out from the common connection point of the probes P1, P2 becomes the same phase as the signal Vref and, when Zx=Zs, Vo=0 is formed and, when Zx<Zs, the signal Vo becomes the same phase as signal reversal Vref and, by this method, the quality of the board Bx is measured by a detector V. The input terminal of the detector V is grounded by a switch S before and after measurement to discharge the residual charge.
