Equipment for electronics
The EPA (Electrostatic Protected Area) is adopted from the area set up for the handling of sensitive ESD components. It can include a place, a warehouse or just a single work station. The EPA area must be identified by the appropriate signs.
Particular attention must be paid to the operators, since being vectors and generators themselves of electrostatic charges it is necessary to put them in a position to work by adopting the best precautions to minimize the generation of charges due.
BRACELETS: the bracelet is the most used device to ground the operator and is able to effectively dissipate the electrostatic charges of the body.
FOOTWEAR: in some locations such as warehouses and near production machinery, conductive shoes or ground covering covers are used.
SHOES: the main purpose to be obtained in wearing a conductive coat is to suppress the electrostatic fields generated by the operator's clothes.
GLOVES: ESD sensitive components can be damaged by electrostatic discharge if touched by a person, even if it is connected to the ground, therefore it is necessary to wear static dissipative gloves and gloves.
PACKAGING AND CONTAINERS
The use of ESD protective packaging has been aimed at preventing direct ESD discharge through the sensitive ESD component contained therein, favoring the possible dissipation of the charges on the outer surface of the packaging. Almost always the insulating packaging is electrostatic charges that can not be discharged a land end up with the knock down on the electrical cards damaging the most sensitive components. Packaging material often adds mechanical protection and blocks contamination from dust and moisture. All devices must be contained in appropriate ESD protective containers.
Sometimes it is not possible to ground the operator (eg High Voltage Areas), or completely eliminate the insulating materials from the protected area. In these cases ionization is a valid system for neutralizing the generated electrostatic charges. The system is in flooding the air with reflections: when the ionized air comes into contact with a charged surface, the surface attracts ions of opposite polarity. The result is the static electricity that is formed on the objects is neutralized. Obviously the functioning system is not limited to disperse the charges, but the formation comes from it.
