High-precision capacitor structure and manufacturing method thereof

Abstract

The present invention discloses a high-precision capacitor structure and a manufacturing method thereof in the capacitor technology field. The high-precision capacitor structure comprises a shell, a capacitor core is packaged in an inner cavity of the shell, and a cathode pin and an anode pin are respectively welded at the left and right ends of the top of the capacitor core. A sealing layer is filled in a cavity between the capacitor core and the shell, a circle of cathode aluminum foil is wound on the outer wall of the capacitor core, and the cathode pin is adhered on the cathode aluminum foil. The circumferential outer wall of the cathode aluminum foil is packaged via a layer of conductive paper, the anode aluminum foil is wound on the outer wall of the conductive paper, the anode pin is adhered on the anode aluminum foil, and the capacitor core is packaged overall via the conductive paper. The high-precision capacitor structure and the manufacturing method thereof are small in sizeand high in capacitor capacity, do not waste the materials easily during the preparation process, and enable the production cost to be reduced and the precision of the capacitor to be improved.

Description

technical field [0001] The invention discloses a high-precision capacitor structure and a manufacturing method thereof, and specifically relates to the technical field of capacitors. Background technique [0002] In recent years, the development of science and technology is changing with each passing day, and various electronic products are becoming more and more common. Therefore, a large number of high-precision capacitors need to be applied. For example, the known single-layer ceramic capacitor uses ceramics as the dielectric material, especially spraying metal on both sides of the ceramic substrate. Then, it is fired into a metal film as an electrode, and then a lead wire is welded on the surface of the electrode as an output and input terminal that can be electrically connected with a circuit board. In the known capacitor manufacturing method, it is not easy to grasp the precision of the capacitor, so the delivery date of the product is not easy to control, and it is ea...
