In order to effectively improve the anti-static characteristics of mobile terminal, analysis the electrostatic discharge damage to mobile terminal which results from conducted interference and radiated interference, electrostatic generator and related auxiliary equipment are used to make a electrostatic discharge test on 20 mobile terminals, experimental result shows that the radiated and conducted interference are the main means of damage. a mobile terminal electrostatic protection measure which makes contra pose to terminal electrostatic damage way is put forwarded, the measure contains: improve the shell structure、increase electrostatic shielding layer、design ground access、design protection circuit, makes a electrostatic discharge test again, the experimental result indicates that there is great improvement on anti-static characteristics of mobile terminal.
