5.6 EMC and ESD Features
Electrostatic Discharge (ESD) is an electrical transient that poses a serious threat to electronic circuits.
The circuit must be configured to protect NAD Module from electrical damage or ESD.
To protect the circuit from ESD, TVS Diode should be added to RF, antenna port, USIM, USB port.
An integrated ground plane is necessary for EMC design.
To protect sensitive circuitry from electrical overstress failures, ESD protection diodes are connected
to each signal line between the interface connector and the NAD Module.
In the factory line, the operator must remove the element that the ESD affects the NAD module.
Operator should wear ESD strap and ESD gloves and work.
