Metal support capacitor with high welding heat resistance and manufacturing method

The embodiment of the invention discloses a metal support capacitor with high welding heat resistance and a manufacturing method. The method comprises the steps that a chip capacitor terminal electrode is prepared, the chip capacitor terminal electrode comprises a first base material and a first plating layer, and the first plating layer is arranged on the surface of the first base material; a metal pole plate is prepared, the metal pole plate comprises a second base material and a second plating layer, and the second plating layer is arranged on the surface of the second base material; welding the first nickel layer of the end electrode of the chip capacitor and the second nickel layer of the metal polar plate by using a high-temperature high-lead solder; the first plating layer is made of nickel or palladium-nickel alloy; the second plating layer is made of nickel or palladium-nickel alloy. According to the invention, the temperature resistance limit of the product after high-temperature welding can be grea
