Abstract:
Presently, the inspection of printed wiring boards includes the conductivity, the capacitance, the appearance inspections, and so forth. There are problems of the conduction defects, the effect of the stray capacitance and the mistaken image in these inspections. In order to resolve these problems, in our research a pin probe with a dielectric substance is produced.
