Abstract
A system for testing the electrical conductivity of printed traces, on multiple surfaces, of a printed wiring board using non-contacting probes. The non-contact probes generate a plasma in a plasma generating chamber that is used to apply a voltage to the printed wiring board. A measurement circuit determines the magnitude of the voltage on the printed wiring board.
