Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board with a protective function. Background Art

[0002] Printed Circuit Board (PCB) is a substrate used to support and connect electronic components. It is made of insulating material and printed with circuits connected by metal wires. PCBs are widely used in various electronic devices, such as computers, mobile phones, household appliances, automotive electronics, etc.

[0003] Since circuit boards are easily affected by dust, the current circuit board structure needs a structure that can effectively block dust. Since there may be static electricity in the dust, when the dust is deposited on the circuit board, the static electricity may pass through the wires and components of the circuit board, causing electrostatic discharge to damage the circuit components. This will cause the function of the circuit board to be impaired or even unable to work properly. In addition, dust accumulation on the circuit board may also block the heat dissipation channel and radiator, hindering the conduction and dissipation of heat. This will cause the temperature of the circuit board to rise, which may cause component failure or performance degradation.

[0004] Therefore, those skilled in the art provide a circuit board with a protection function to solve the problems raised in the above background technology. Utility Model Content
