Compared with prior art; The present invention will inhale the electromagnetic shielding component that the ripple paster is used as portable terminal; Can not only play shielding action, can also be with the absorption of electromagnetic radiation in the electromagnetic shielding component, the coupling and the reflection that prevent electromagnetic radiation cause crosstalks; Can also absorb the outside space radiation of radome, reduce the injury of radiation the user.Simultaneously, the bionical suction ripple paster cost of employing is lower, has further reduced the manufacturing cost of portable terminal.
Embodiment
The present invention provides a kind of portable terminal, and is clearer, clear and definite for making the object of the invention, technical scheme and effect, below to further explain of the present invention.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Because the electromagnetic shielding component in the existing portable terminal only has shielding action, do not have the ripple effect of inhaling, the electromagnetic radiation in the electromagnetic shielding component is easy to cause through aerial coupling and reflection crosstalks other elements in the EVAC.Therefore, in the present invention,, can not only play shielding action with inhaling the electromagnetic shielding component of ripple paster as portable terminal, can also be with the absorption of electromagnetic radiation in the electromagnetic shielding component, the coupling and the reflection that prevent electromagnetic radiation cause crosstalks.Said suction ripple paster can also absorb the outside space radiation of radome, reduces the injury of radiation to the user.
Said suction ripple paster comprises substrate and inhales the ripple particulate, inhales the ripple particulate and is attached on the substrate through binding agent, forms described suction ripple paster through compression forming.Said suction ripple particulate has microwave and absorbs and reflex.The material of said suction ripple particulate can be metal powder, metallic fiber, sheet metal or polycrystalline ferrite etc.Said binding agent can be sheet, spherical or rod-shaped material etc.
In the present invention program; Preferably will inhale the electromagnetic shielding component of ripple paster as portable terminal; Be about to this suction ripple paster and use as electro-magnetic shielding cover, this suction ripple paster preferably is substrate with the spirulina, inhales the ripple particulate at the surface deposition of spirulina substrate; Said suction ripple particulate adheres on the spirulina substrate through bonding agent, forms bionical suction ripple paster through compression forming.This bionical suction ripple paster has characteristics with low cost, excellent performance with respect to other general suction ripple pasters.
As electromagnetic shielding component, above-mentioned bionical suction ripple paster can be fixed on the said pcb board through the mode that adheres to or weld.When electromagnetic shielding component is fixed on the pcb board through the mode of welding; Said portable terminal can be employed in a fixing support on the pcb board, and this support is welded on the pcb board through SMT (surface mounting technology), then bionical suction ripple paster is fixed on the support; Fixed form preferably adopts the mode of adhesion; Also can adopt fixed form well known in the prior art, be fixed on the said pcb board, form electro-magnetic shielding cover thereby will inhale the ripple paster.
Said portable terminal can be that standard is the mobile phone of TD-SCDMA, WCDMA or CDMA etc.It also can be panel computer.
It is the embodiment of mobile phone that said portable terminal also is provided among the present invention; Said mobile phone is when the pcb board structural design; Be preferably baseband circuit part and radio circuit part are concentrated setting respectively, directly over baseband circuit part and radio circuit part, be respectively arranged with said suction ripple paster.Because the baseband circuit part is different with the frequency of electromagnetic radiation of radio circuit part, is fixed with the suction ripple paster suitable with its frequency of electromagnetic radiation above it respectively.As, the frequency of electromagnetic radiation of baseband portion mainly concentrates on below the 1GHz, and then said baseband portion adopts the suction ripple paster that adapts to the 1GHz frequency range as electromagnetic shielding component; The frequency of electromagnetic radiation of radio frequency part concentrates on more than the 2GHz, and then said radio frequency part adopts the suction ripple paster that adapts to the 2GHz frequency range as electromagnetic shielding component.On the pcb board structure, carry out the fixed position of electromagnetic shielding component, said suction ripple paster just can adhere to or be welded on base band and radio circuit the part directly over.
