Abstract
The utility model relates to an electromagnetic interference resistance printed circuit board, include the printed circuit board who constitutes by upper PCB board and lower floor's PCB board, wherein be in set up absorbing material layer between upper strata PCB board, the PCB of the lower floor board. Ordinary printed wire effectively protects with the electromagnetic interference of inside is unable to external world, adopts an electromagnetic interference resistance printed circuit board, have can effectively reduce on the printed circuit board electrical components and functional module received comes from outside with the inside electromagnetic interference's of printed circuit board advantage.
Description
Technical field
This utility model belongs to printed substrate technical field, is specifically related to a kind of anti-electromagnetic interference printed substrate.
Background technology
Multifunction along with electronic product, get more and more in the upper integrated functional module of printed substrate (PCB), add electronic product and there is this bigger uncertainty in the environmental change of practical application, so about how reducing the problem that the external world or the electromagnetic interference of self have just become puzzlement printed substrate designer.In actual process, a lot of designers, it is also contemplated that a lot of way, as there is the key position of comparatively serious electromagnetic interference on a printed-wiring board, pasting absorbing material and preventing electromagnetic interference.But such measure can only play a role, wiring board can not be all pasted together by absorbing material after all, so electromagnetic interference cannot better be completely cut off.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of anti-electromagnetic interference printed substrate.This printed substrate can effectively reduce from the outside and internal electromagnetic interference (EMI) of printed substrate, it is ensured that electric elements on printed substrate and functional module properly functioning.
For reaching object above, the technical solution adopted in the utility model is a kind of anti-electromagnetic interference printed substrate, including the printed substrate being made up of upper strata pcb board and lower floor's pcb board, wherein arranges absorbing material layer between described upper strata pcb board, lower floor's pcb board.
Further, described absorbing material layer is Ferrite Material.
Further, described absorbing material layer is arranged between described upper strata pcb board, lower floor's pcb board by laminating technology.
Further, described absorbing material layer 4 thickness is 0.06-1.1mm.
The beneficial effects of the utility model have following some:
1. can effectively reduce the electric elements on printed substrate and suffered by functional module from printed substrate electromagnetic interference outwardly and inwardly；
2. technique is simple, uses the laminating technology of routine, it is not necessary to existing equipment is transformed；
3. Ferrite Material isolation electromagnetic interference effective, life-span length, cost are not high.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of anti-electromagnetic interference printed substrate described in this utility model detailed description of the invention；
In figure: 1-printed substrate, 2-upper strata pcb board, 3-lower floor pcb board, 4-absorbing material layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As it is shown in figure 1, a kind of anti-electromagnetic interference printed substrate, including the printed circuit board (PCB) 1 of the layering being made up of upper strata pcb board 2 and lower floor's pcb board 3, it is arranged on the absorbing material layer 4 between upper strata pcb board 2 and lower floor's pcb board 3.
Absorbing material layer 4 adopts Ferrite Material to make, and is arranged on upper strata pcb board 2 and the centre of lower floor's pcb board 3 by laminating technology.Laminar manner is according to the pressing mode of multilayer printed circuit board.The thickness of absorbing material layer 4 is 0.06-1.1mm.
The concrete processing technology of a kind of anti-electromagnetic interference printed substrate provided by the utility model is shown in following table:
Device described in the utility model is not limited to the embodiment described in detailed description of the invention, and those skilled in the art draw other embodiment according to the technical solution of the utility model, also belongs to technological innovation scope of the present utility model.
