Abstract

The invention discloses an aluminum electrolytic capacitor which comprises a body and a lead, the lead comprises a root part, a tip part and a bending part, the root part is subjected to insulation treatment, the bending part is provided with an arc bending structure, and the tip part comprises a spring-shaped buffer structure; a circuit board assembly comprises a circuit board, the aluminum electrolytic capacitor and other electronic devices, the mounting area of the aluminum electrolytic capacitor is located on the front face of the circuit board, and the body of the aluminum electrolytic capacitor penetrates through the circuit board to be located on the back face, so that the aluminum electrolytic capacitor is inversely arranged on the circuit board. According to the scheme, the aluminum electrolytic capacitor is inversely arranged in the perforated circuit board in a front surface mounting manner, so that the circuit board can be normally conducted to work through the aluminum electrolytic capacitor, the luminous flux is improved, meanwhile, a connector is omitted, and the cost is reduced. And the steps of welding the connector on the circuit board and then installing the aluminum electrolytic capacitor in a plug-in manner in the prior art are omitted, so that the electric connection of the circuit board is realized simply and reliably.

Description

technical field [0001] The application belongs to the field of electronic technology, and in particular relates to an aluminum electrolytic capacitor, a circuit board assembly and a preparation method thereof. Background technique [0002] In the existing driving linear scheme, the driving components and the light source are integrated on the same printed circuit board (PCB). Among them, the installation methods of aluminum electrolytic capacitors include automatic patching on the front of the PCB and manual insertion on the back of the PCB. In the case of a large number of components, the automatic placement scheme on the front of the PCB has the problems of insufficient creepage distance and structural interference. At the same time, due to the high aluminum electrolytic capacitor, it will also produce light source shadows. The installation scheme of the manual plug-in on the back usually involves the installation of the connector. For example, first open a hole in the PC...
