| description | The invention discloses a composite welding method for a thin-film capacitor core and an extraction electrode, which belongs to the technical field of thin-film capacitors and comprises the following steps of: performing electric resistance welding on a metal surface of the thin-film capacitor core and a welding point of a copper bar, and welding a tin layer on the surface of the welding point of the copper bar with the metal surface of the core, good strength and electrical connection are formed between the copper bar and the core; welding is conducted in a tin soldering mode, soldering iron contact welding points are preheated firstly, after the temperature of the metal surface of the core and the temperature of the copper bar rise, a soldering tin wire is fed, the soldering tin wire makes contact with a soldering bit to be melted, and composite welding of the film capacitor core and the extraction electrode is achieved after tin is flatly spread, the soldering bit leaves and is cooled.
