Abstract
Gas plasma reactor for treatment of printed circuit boards and other relatively large, generally planar objects. The reactor includes a rack assembly having a plurality of spaced apart bars for holding the objects and a pair of generally planar electrodes positioned outside the rack assembly. The rack assembly is maintained at ground potential, and the electrodes are energized with RF energy to form an ionizing field between the electrodes and the rack bars.
