[0002] PCB (Printed Circuit Board), also known as printed circuit board in Chinese, is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.

[0003] The existing high-power printed circuit boards still have some defects. Most of them do not have the function of automatic cleaning of the dust net. The circuit board will generate a lot of heat when working, which needs to be discharged through the heat dissipation holes. Dust nets are set at the heat dissipation holes. Over time, a lot of dust will accumulate on the surface of the dust net. If it is not removed in time, it may affect the normal heat dissipation of the circuit board and reduce the service life of the circuit board. For this reason, we propose a heat dissipation type high-power printed circuit board. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The automatic cleaning function of the filter is realized by the provided strip holes, sliders, threaded rods, motors and brush plates. It only needs to start the motor to drive the threaded rods to rotate, thereby driving the sliders to slide inside the strip holes, and then driving the brush plates to clean the dust screen. No manual cleaning is required, which saves time and effort and improves the heat dissipation effect of the circuit board.
