发明名称 DEVICE AND METHOD FOR PRODUCING TARGETED FLOW AND CURRENT DENSITY PATTERNS IN A CHEMICAL AND/OR ELECTROLYTIC SURFACE TREATMENT
摘要 The invention relates to a device and method for producing targeted flow and current density patterns in a chemical and/or electrolytic surface treatment. The device comprises a flow distributor body which is disposed, with the front face thereof, plane-parallel to a substrate to be processed, and which has outlet openings on the front face, through which process solution flows onto the substrate surface. The process solution flowing back from the substrate is led off through connecting passages onto the rear face of the flow distributor body. At the same time a targeted distribution of an electrical field on a conductive substrate surface is effected by a specific arrangement of said connecting passages.
