The invention discloses a metallic coating, a coating machine for producing the metallic coating and a technology which is used for evaporating the metallic coating and is applied on the coating machine, wherein the metallic coating comprises an insulation thin layer and a metal plating which is plated on the thin layer, the metal plating is varied in a curved shape, and comprises a thickening area with thickened edges, a low resistivity area which varies in an N-type sine half wave shape and a high resistivity area which is in a long and narrow strip shape, the low resistivity area joins the thickening area and the high resistivity area, and arc transition is adopted between the low resistivity area and the thickening area as well as the low resistivity area and the high resistivity area. The metallic coating is characterized in that the edge of a metallic coating sheet resistance for a capacitor can be thickened, an active area varies according to the N-type sine half wave shape, the current density of a dielectric surface when the capacitor works is distributed in a balanced manner, so the requirements of inrush current resistance, low temperature rise and aging resistance are met.
Description
technical field [0001] The invention relates to a metallized film, a film coating machine and an evaporation metallization film process, in particular to an innovative process control method for an evaporation metallization film, which is suitable for the production of metallization films for power electronics AC and DC filter capacitors, so that the metal Power electronic capacitors made of chemical film materials have the properties of anti-inrush current, low thermal resistance, small temperature rise and long life. Background technique [0002] At present, power electronic AC and DC filter capacitors are used in inverters, and the general life span cannot meet the design requirements. Changing the performance and requirements of such capacitor materials is a way to improve capacitor performance, and with the continuous development of new energy sources, the The performance requirements of capacitors will be higher and higher. [0003] Generally, the traditional metalliz...
