Description
Technical field:
The utility model relates to insulation and technical field of electromagnetic shielding, refers in particular to a kind of Novel soft electromagnetic shielding film.
Background technology:
Electronic electric equipment digitlization increasingly, Highgrade integration, signal level small quantization, to meet the requirement of its high speed, lightweight and miniaturization, right electronic devices and components very easily produce misoperation by outside electromagnetic interference, have serious consequences; Electromagnetic wave also can cause damage to human body in addition.Therefore, in the design of electronic electric equipment, except correct design circuit and rational deployment electronic component, adopt electromagnetic shielding material to be the choose reasonable eliminating and weaken electromagnetic interference, conventional electromagnetic shielding material is software electromagnetic shielding film.
At present, existing software electromagnetic shielding film is generally cloth is carried out plating to form metallized fabrics, software electromagnetic shielding film is soft, smooth, and there is the advantages such as lightweight and easy cutting, but, along with the trend of miniaturization of electronic products, ultrathin, propose requirements at the higher level to the shielding properties of shielding material and insulation property, existing shielding material cannot meet the demands.
Utility model content:
The purpose of this utility model is for the deficiencies in the prior art, and provides a kind of Novel soft electromagnetic shielding film, the simple science of its structural design, avoids electronic devices and components when mutually superposing, and produces the phenomenon of short circuit, also effectively prevents electromagnetic radiation simultaneously.
For achieving the above object, the utility model comprises screen, insulating barrier, carrier film, conductive adhesive layer, diaphragm, metal protection layer, and the lower surface of screen is provided with insulating barrier, carrier film successively, and the upper surface of screen is provided with conductive adhesive layer, diaphragm successively.
Described insulating barrier is painting black polyurethane on a carrier film, and thickness is the insulating barrier of 0.003-0.007mm.
Described shielding thickness is 0.001-0.002mm,
Described conductive adhesive layer thickness is 0.005-0.01mm.
The utility model beneficial effect is: screen, insulating barrier, carrier film, conductive adhesive layer, diaphragm, metal protection layer; the lower surface of screen is provided with insulating barrier, carrier film successively; the upper surface of screen is provided with conductive adhesive layer, diaphragm successively; the simple science of its structural design; avoid electronic devices and components when mutually superposing; produce the phenomenon of short circuit, also effectively prevent electromagnetic radiation simultaneously.
Accompanying drawing illustrates:
Fig. 1 is cutaway view of the present utility model.
Embodiment:
As shown in Figure 1: the utility model comprises screen 1, insulating barrier 2, carrier film 3, conductive adhesive layer 4, diaphragm 5, metal protection layer 6; the lower surface of screen (1) is provided with insulating barrier 2, carrier film 3 successively, and the upper surface of screen 1 is provided with conductive adhesive layer 4, diaphragm 5 successively.
Described insulating barrier 2 is painting black polyurethane on a carrier film, and thickness is the insulating barrier of 0.003-0.007mm.
Described screen 1 thickness is 0.001-0.002mm,
Described conductive adhesive layer 4 thickness is 0.005-0.01mm.
Namely there is the effect of electromagnetic wave shielding, have again the effect of insulation.Under the development trend of existing miniaturization of electronic products, avoid electronic devices and components when mutually superposing, produce the phenomenon of short circuit, also effectively prevent electromagnetic radiation simultaneously.
This insulating barrier 2 is painting black polyurethane coating on a carrier film, and forming thickness is the insulating barrier of 0.007mm; Vacuum sputtering of metal screen is utilized again, applying conductive glue-line 4 on metal screen layer, covered with protective film on conductive adhesive layer 4 on insulating barrier 2.Shielding thickness is 0.001mm, and conductive adhesive layer 4 thickness is 0.01mm, and forming gross thickness is the effect that can reach shielding, and thickness is the electromagnetic shielding film of 0.018mm.
The above is only preferred embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
