Environmental treatment As shown in the figure: add conductive foam at the corresponding position of the red arrow to ground the battery back cover Shenzhen Xinbinuo Communication Technology Co.
As shown in the figure, conductive sponge is pasted in the red box to fully ground the main board and screen metal frame As shown in the red box below: connect conductive cloth from the SIM card slot to the screen metal to cover the camera FPC flat cable for grounding Shenzhen Xinbinuo Communication Technology Co.
As shown in the figure, conductive cloth is used to ground the flat wire below the screen in the red box Shenzhen Xinbinuo Communication Technology Co.
As shown in the figure, a conductive cloth is pasted on the FPC cable at the upper right corner of the main board and a conductive foam is pasted inside the screen metal grounding blue box to ground the battery back cover As shown in the red box of the figure, double-sided conductive cloth is pasted on the back of the small board of the main antenna to ground the screen metal, and conductive cloth is pasted on the exposed copper part of the small board of the main antenna to extend to the grounding of the
As shown in the figure below, the conductive cloth is pasted at the exposed copper part of the three in one small plate in the green box, and extended to the grounding at the metal part of the screen. The conductive foam is pasted in the blue box and grounded with the battery back cover。 As shown in the figure, the copper exposed point of diversity antenna shall be pasted with conductive cloth and extended to the screen metal for grounding Shenzhen Xinbinuo Communication Technology Co.
As shown in the red box of the figure, the screen flat cable has a great impact on the sensitivity of the bright screen. Pull a large piece of conductive cloth at the shielding cover of the main board to extend to the metal of the screen to cover the interface between the main board and the flat cable to shield interference.
