Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board convenient for heat dissipation. Background Art

[0002] A circuit board is also called a printed circuit board. The circuit board miniaturizes and visualizes the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. According to the number of layers, circuit boards are divided into three major categories: single-sided boards, double-sided boards, and multi-layer circuit boards. A single-sided board, on the most basic PCB, components are concentrated on one side, and conductors are concentrated on the other side. Since the conductors only appear on one side, this kind of PCB is called a single-sided circuit board. Single-sided boards are usually simple to manufacture and low in cost, but the disadvantage is that they cannot be applied to too complex products. 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. There is copper plating and traces on both sides, and the circuits between the two layers can be conducted through vias to form the required network connections. A multi-layer board refers to a printed circuit board formed by laminating three or more conductive pattern layers and the insulating materials between them with intervening layers, and the conductive patterns are interconnected as required. Multi-layer circuit boards are the products of the development of electronic information technology towards high speed, multi-function, large capacity, small volume, thinness, and light weight.

[0003] In the prior art, when a circuit board is in use, a large amount of heat is generated when the electronic components arranged on the circuit board work. Generally, the circuit board is arranged inside various machines, and the ventilation is poor. The heat is easy to accumulate on the circuit board and cannot be dissipated, thus burning out the electronic components and affecting the working efficiency. Based on this, this application proposes a circuit board convenient for heat dissipation to solve the above problems. Summary of the Utility Model
