Film capacitor metal spraying process

Abstract

The invention discloses a film capacitor metal spraying process. The first end face of the film capacitor is subjected to first time metal spraying, the second end face of the film capacitor is subjected to first time metal spraying, the first end face of the film capacitor is subjected to second time metal spraying, the second end face of the film capacitor is subjected to second time metal spraying, the first end face of the film capacitor is subjected to third time metal spraying, the second end face of the film capacitor is subjected to third time metal spraying, and the first end face and the second end face are two opposite end faces of the capacitor. Through carrying out the first time metal spraying of the first end face of the capacitor and then the first time metal spraying of the second end face of the capacitor and so on, the two end faces are subjected to metal spraying, the pollution of another end face by the metal spraying of a single end face for many times is reduced, and a problem of a capacitor failure caused by poor welding of a capacitor end face can be solved.

Description

technical field [0001] The present disclosure generally relates to the field of capacitor processing, specifically relates to the field of capacitor gold spraying technology, and particularly relates to a film capacitor gold spraying process. Background technique [0002] There are many types of capacitors depending on the medium, such as: electrolytic capacitors, paper capacitors, film capacitors, ceramic capacitors, mica capacitors, air capacitors, etc. However, the most frequently used in audio equipment are electrolytic capacitors and film (Film) capacitors. Electrolytic capacitors are mostly used in places that require a large capacitance, such as the filter capacitor of the main power supply, which is used for storing electric energy in addition to filtering. Film capacitors are widely used in the cross-connection of analog signals and the bypass (reverse cross-connection) of power supply noise. [0003] Film capacitors use metal foil as an electrode, and it is lamin...
