Self-cleaning PCB

Abstract

The invention discloses a self-cleaning PCB which comprises a PCB, a copper foil layer, a resin bonding layer, a flame-retardant insulating bottom plate, a connecting upper clamping plate, a knob, athreaded rod, a connecting lower clamping plate, a fixing screw, a mounting plate, a fixing bottom plate, a lower connecting plate, a rotating shaft, a rubber pad layer, a fixing clamping plate, an upper connecting plate, a micro fan, an upper fixing plate, a damping spring, a round fixing shell, a connecting round rod, a fixing round plate and a rubber gasket. The self-cleaning PCB has the beneficial effects that the device is reasonable in structure; the heat dissipation effect on the PCB can be achieved through the micro fan; heat accumulation and component damage caused by the too high temperature of the PCB in the using process are avoided; meanwhile, dust accumulated on the surface of the PCB can be blown away by the micro fan; dust is prevented from being accumulated on components;and the self-cleaning effect is achieved.

Description

technical field [0001] The invention relates to a PCB board, in particular to a self-cleaning PCB board, and belongs to the technical field of PCB board application. Background technique [0002] The names of circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. [0003] When using the PCB board, you need to pay attention to many problems. Because the PCB board itself has many electronic components, it is easy to generate electrostatic adsorption of dust from the outside, which will lead to dust accumulation for a lo...

Problems solved by technology

[0003] When using the PCB board, you need to pay attention to many problems. Because the PCB board itself has many electronic components, it is easy to generate electrostatic adsorption of dust from the outside, which will lead to dust accumulation for a long time, affect the life of the electronic components, and cause maintenance. At the same time, the current PCB board is usually It is fixed on the corresponding mounting plate with screws, which is laborious to disassemble and difficult to repair and replace.
