Abstract

The invention relates to a metallized film for a thin film capacitor, comprising a dielectric layer and a metallized film layer, the metallized film layer and the dielectric layer are combined with each other, and a misaligned edge is left at one end of the dielectric layer. The metallized film layer is in a triangular shape; the thicker side of the metallized film layer is located at the metallized edge after the metallized film layer is combined with the dielectric layer. The present invention also relates to a method for making a metallized film for a film capacitor of the present invention, comprising the following steps: coating a metal material on a dielectric layer, leaving a wrong edge at one end of the dielectric layer to form a metallized film layer, and The metallized film layer is in a triangular shape, wherein the thicker side of the metallized film layer is located at the metallized edge after the metallized film layer is combined with the dielectric layer. The processing technology of the invention is simple, and the contact resistance of the thin film capacitor made by it is small, so that the characteristics of the product are good.

Description

technical field [0001] The invention relates to the technical field of metallized films, in particular to a metallized film for film capacitors and a manufacturing method thereof. Background technique [0002] Existing metallized films such as figure 1 As shown, it includes a dielectric layer 1, a metallized film layer 2 and a metal thickened layer 3. The metallized film layer 2 and the dielectric layer 1 are combined with each other, and a misalignment 11 is left at one end of the dielectric layer 1, and the metal thickened layer 3 is set The metallized edge after the metallized film layer 2 is combined with the dielectric layer 1. The manufacturing process of this structure is complicated, and the contact resistance of the thin film capacitor made with it is large, which affects the product characteristics. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metallized film for film capacitors and its manufactu...
