Surface treatment method e.g. for flat substrates and circuit-boards, involves treating surface with air-ionization by electrical discharge at high-voltage

摘要

A method for treating/processing the surface of a flat substrate (20) for removing impurities from the surface or for improving the surface wetting properties of the surface. The surface is treated with air-ionization (22) by electrical discharge at high-voltage (HV) between at least one electrode (13) and at least one counter-electrode (16). INDEPENDNET CLAIMS are included for (a) a device for treating the surface of a substrate and for (b) application of an air-ionization device.
