ESD prevention within an EPA may include using appropriate ESD-safe packing material, the use of conductive filaments on garments worn by assembly workers, conducting wrist straps and foot-straps to prevent high voltages from accumulating on workers ' bodies, anti-static mats or conductive flooring materials to conduct harmful electric charges away from the work area, and humidity control.

ESD and prevention
ESD prevention can be part of the device itself and include special design techniques for device input and output pins.
ESD prevention activities are therefore important with those processes where component is touching on equipment surfaces.
ESD and within
The ESD determines the external parameters such as acceleration curve, temperature and pressure and only activates the weapon when these external effects occur in the correct order and must fall within specific parameters.
ESD and EPA
Prevention of ESD bases on Electrostatic Protective Area ( EPA ).
The main principle of an EPA is that there are no highly charging materials in the vicinity of ESD sensitive electronics, all conductive materials are grounded, workers are grounded, and charge build-up on ESD sensitive electronics is prevented.
ESD and may

ESD and material
Materials in automated manufacturing which will touch on conductive areas of ESD sensitive electronic should be made of dissipative material, and the dissipative material must be grounded.
ESD effects can be reduced by careful design of the mechanical package around the hot-swap component, perhaps by coating it with a thin film of conductive material.
ESD and use
An efficient way to prevent ESD is to use materials that are not too conductive but will slowly conduct static charges away.
For voltage signals, it is customary to use units of V < sup > 2 </ sup > Hz < sup >− 1 </ sup > for PSD, and V < sup > 2 </ sup > sHz < sup >− 1 </ sup > for ESD.

ESD and conductive
The most spectacular form of ESD is the spark, which occurs when a heavy electric field creates an ionized conductive channel in air.
In addition, it is important to prevent ESD when an electrostatic discharge sensitive component is connected with other conductive parts of the product itself.
