ABSTRACT:
A method of de-burring and cleaning an electrode system, a printed circuit board, or the like comprising at least two conductors positioned at a predetermined distance from each other by means of insulation material. The electrode system is immersed in a dielectric liquid and an electric potential difference is then applied between the conductors which is sufficiently large to generate an electric flash-over between the conductors. As a result of the small free path length in the dielectric liquid metal sputtered from the conductors can not deposit on the insulating parts of the electrode system.
