ABSTRACT:
A voltage is applied between a first cleaning electrode that in contact with an electrode on a workpiece such as a printed circuit board or a chip, and a second cleaning electrode located in the vicinity of the electrode on the workpiece, from a voltage application circuit so as to produce an electric discharge on the electrode on the workpiece, whereby contamination sticking to the electrode on the workpiece is locally removed by heat generated from the electric discharge.
