Description

[0002] A thin film capacitor is a capacitor with a structure in which metal foils are used as electrodes and are overlapped at both ends with plastic films such as polyethylene terephthalate, polypropylene, polystyrene, or polycarbonate and then wound into a cylindrical shape; due to many excellent characteristics, thin film capacitors are a type of capacitor with excellent performance. In order to ensure the quality of the thin films leaving the factory, it is necessary to detect the aging resistance performance of the thin films to ensure that the thin films have sufficient service life. Therefore, a thin film aging resistance testing machine for thin film capacitors is designed.
