Abstract

The invention discloses a half-breadth metallization safety film, and relates to the technical field of capacitors. The half-breadth metallization safety film comprises a base film. When vapor deposition is carried out on the base film, the oil shielding technology or the belt shielding technology is adopted on one half of the breadth of the base film, so that metal can not be plated on a plurality of disconnected small pattern areas, a plurality of micro fuses are formed, and the metallization safety film is formed. Shielding processing is not carried out on the other half of breadth, the whole metallization area is formed, a common metallization film is formed, after the vapor deposition is completed, slitting is carried out, the matching metallization safety film and the common metallization film which are completely consistent in performance can be obtained, a metallization safety film capacitor manufactured by the matching films is good in performance consistency and stability, and the service life of the capacitor is greatly prolonged.

Description

technical field

[0001] The invention relates to the technical field of capacitors, in particular to a half-width metallized safety film. Background technique

[0002] Film capacitor is a capacitor with superior performance, which has the following main characteristics: non-polarity, high insulation resistance, excellent frequency characteristics, small dielectric loss, and small volume and large capacity. Therefore, film capacitors have a wide range of uses and can form different series of products, such as high specific energy storage capacitors, anti-electromagnetic interference capacitors, anti-radiation capacitors, safety film capacitors, long-life capacitors, high-reliability capacitors, and high-voltage full-film capacitors Wait. Metallized safety film is to design multiple disconnected small patterns in the metal area of ​​the film, and divide the metal layer into many small areas connected by very narrow metal channels (miniature fuses). When in use, when excessive...
