Description

Technical Field

[0001] The utility model relates to the field of circuit boards, in particular to a circuit board with component protection effect. Background Art

[0002] A circuit board is a substrate used to support and connect electronic components. Electronic components such as chips, resistors, capacitors, connectors, etc. can be laid out and interconnected on the circuit board. Electronic components are the basic building blocks of electronic circuits and are used to perform specific functions in the circuits. These components can be passive components or active components. During the use of existing circuit boards, the components on the circuit boards often generate high temperatures after work. Currently, circuit boards on the market can only rely on the components themselves for cooling and heat dissipation, which can easily lead to a reduction in the service life of the components. During use, a lot of dust often accumulates on the surface of the circuit boards and the surfaces of the circuit boards, which can easily lead to a short circuit between the components and the circuit boards, causing damage to the components. Therefore, we propose a circuit board with component protection effect to solve the above problems. Utility Model Content
