Abstract
The utility model relates to a PCB, and especially relates to a dustproof type PCB. The PCB comprises a conducting layer, an insulating layer, and a heat radiation layer. The insulating layer is disposed on the heat radiation layer. The conducting layer is disposed on the insulating layer. Dust collection devices are fixed on side edges of the conducting layer. Static filter screens are disposed in the dust collection devices. The PCB can absorb dusts on the board to keep clean on the surface, thereby prolonging service life of the PCB.
Description
Technical field
The utility model relates to a kind of pcb board, especially dust-protection type pcb board.
Background technology
PCB(Printed Circuit Board), Chinese is printed circuit board, claims again printed circuit board (PCB), printed substrate, is important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.In prior art, PCB plate is widely used, and well-known electronic component can affix dust in the course of the work, and the time is easily caused the damage of device and aging after having grown because of the accumulation of dust.
Utility model content
In order to overcome the deficiency of the easy sedimentating dust of existing pcb board, the utility model provides dust-protection type pcb board.
The utility model solves the technical scheme that its technical problem adopts: dust-protection type pcb board, comprise conductive layer, insulating barrier and heat dissipating layer, and heat dissipating layer is provided with insulating barrier, and insulating barrier is provided with conductive layer, and conductive layer side is fixed with dust exhaust apparatus.
According to another embodiment of the present utility model, further comprise and in dust exhaust apparatus, be provided with static filter screen.
The beneficial effects of the utility model are, the dust that this pcb board is piled up on can baffle, keeps its surface cleaning, has extended its useful life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
1. conductive layers in figure, 2. insulating barrier, 3. heat dissipating layer, 4. dust exhaust apparatus, 5. static filter screen.
Embodiment
If Fig. 1 is structural representation of the present utility model, dust-protection type pcb board, comprises conductive layer 1, insulating barrier 2 and heat dissipating layer 3, heat dissipating layer 3 is provided with insulating barrier 2, insulating barrier 2 is provided with conductive layer 1, and conductive layer 1 side is fixed with dust exhaust apparatus 4, is provided with static filter screen 5 in dust exhaust apparatus 4.
When using this pcb board, just open the dust exhaust apparatus 4 of conductive layer 1 side, the dust sticking in like this on conductive layer 1 can be inhaled in dust exhaust apparatus 4, and dust can be bonded on static filter screen 5, the dust that this pcb board is piled up on can baffle, keep its surface cleaning, extended its useful life.
