ESD and EMI hazards in mobile phones--Solutions for the audio system connectorBy Richard Renard, STMicroelectronics Mobile Handset DesignLine (06/15/08, 12:35:00 PM EDT) Modern materials and technology produce electro-static discharge (ESD) and electro-magnetic interference (EMI) as ever-present hazards. What we wear and what we touch create potential for ESD. Digital technology has added to the EMI hazard always present in any electrical device. ESD can destroy electronic components in mobile phones. The mobile phone can be easily replaced but the disruption to the user can be significant. Circuit designers need to ensure that they employ measures to suppress the potentially damaging effect of ESD.
