[0002] Circuit boards are divided into single-sided boards, double-sided boards, and multi-layer boards; for a single-sided board, on the most basic PCB, components are concentrated on one side, and conductors are concentrated on the other side; a double-sided board is an extension of a single-sided board. When single-layer wiring cannot meet the needs of electronic products, a double-sided board is used; a multi-layer board refers to a printed circuit board formed by laminating three or more conductive pattern layers and insulating materials therebetween with intervening layers, and the conductive patterns therein are interconnected as required.

[0003] However, for existing circuit boards with a solder dragging structure, due to the material of the circuit board, it is inevitable to have excess solder during the soldering process. Therefore, it is necessary to clean the excess solder. After the circuit board is installed, external forces need to be avoided acting on the outer wall, which may affect the use of the circuit board. During long-term use, the circuit board will generate a certain amount of heat, which will affect the service life of the circuit board. Summary of the Utility Model
