Problems solved by technology

However, the capacitors of the prior art still have disadvantages to be improved
Specifically, when a conductive polymer is used as a solid electrolyte, based on the characteristics of the conductive polymer dispersion itself, it is difficult to fully adhere to the corroded surface of the capacitor element.

Abstract

The invention discloses an anti-surge capacitor and a manufacturing method thereof. The manufacturing method of the anti-surge capacitor comprises the following steps: (a) providing a capacitor substrate, and performing corrosion treatment on the surface of the capacitor substrate to form a corroded surface; (b) using the first conductive polymer dispersion to process the corrosion surface; (c) using the second conductive polymer dispersion to treat the corroded surface; wherein, step (b) and step (c) are to process the corroded capacitor substrate according to a predetermined sequence, so as to form a conductive high Molecular layer; wherein, the concentration of the first conductive polymer dispersion is different from the concentration of the second conductive polymer dispersion. The anti-surge capacitor of the invention has the electrical characteristics of anti-surge and reduced capacity failure rate. The invention also discloses an anti-surge capacitor.

Description

technical field [0001] The invention relates to a method for manufacturing a capacitor, in particular to an anti-surge capacitor and a method for manufacturing the same. Background technique [0002] Capacitors have been widely used in basic components of consumer appliances, computer motherboards and their peripherals, power supplies, communication products, and automobiles. Their main functions include: filtering, bypassing, rectifying, coupling, decoupling, The converter is one of the indispensable components in electronic products. Capacitors have different types according to different materials and uses, including aluminum electrolytic capacitors, tantalum electrolytic capacitors, multilayer ceramic capacitors, and film capacitors. In the prior art, solid electrolytic capacitors have the advantages of small size, large capacitance, and superior frequency characteristics, and can be used for decoupling of the power supply circuit of the central processing unit. Solid e...
