Problems solved by technology

In the above manufacturing process, due to the vibration in the mechanical manufacturing process, although it has no effect on the electrical properties and life of the capacitor, the vibration sound may cause noise and reduce the quality of the coated capacitor
The reason for the noise is that when the film capacitor is coiled, due to the elasticity of the automatic coiler, there is a gap between the films.
In addition, when the coiled elements are impregnated, when the wax is not completely impregnated, the capacitor will generate noise

Abstract

The invention relates to the technical field of electron, in particular to a manufacturing method of a cylindrical capacitor. The manufacturing method of the cylindrical capacitor comprises the following steps: coiling; heat treatment; packaging: packaging a prime by a paper adhesive tape so as to prevent tin powder from being sprayed on the surface of the prime in the spraying process, and spraying the tin powder on the two ends of the prime; fusion welding: welding pin lines; dipping; powder coating: carrying out external powder coating, and hardening and drying the powder; examination: examining construction, automatically selecting, and finally examining series of checked operations; and pin processing. Compare with the common compression capacitor, the invention can reduce 30-40% of noise and increase 10% of available current and has the obvious advantages of reasonable structure, convenient use, excellent performance and the like.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for manufacturing a cylindrical capacitor. Background technique [0002] As we all know, capacitance is a physical quantity that characterizes the ability of a capacitor to hold charges. A capacitor is a storage medium for static charges. It has a wide range of uses in industrial production and life. It is an indispensable component in the field of electronics and electric power. It is mainly used for power filtering. , Signal filtering, signal coupling, resonance, DC blocking and other circuits. According to different materials and structures, capacitors are divided into electrolytic capacitors, solid capacitors, ceramic capacitors, tantalum electrolytic capacitors, mica capacitors, glass glaze capacitors, polystyrene capacitors, glass film capacitors, alloy electrolytic capacitors, polyester capacitors, polypropylene capacitors, etc. Among them, the film capacitor...
