What are the electrostatic protection requirements of employees?
1. Wear anti-static overalls and anti-static shoes as required.
2. Before touching the static sensitive components, you must wear the grounding wrist strap or the grounding strap as required, and pass the corresponding static test.
3. Items that are prone to static electricity are prohibited from being brought into the anti-static area.
EPA (ESD-protected area) - A controlled working environment in which the electrostatic voltage of materials and equipment is controlled. Areas that are built and equipped with the necessary antistatic materials and equipment to protect the electrostatic sensitive device (ESSD) from static electricity, usually have obvious anti-static warning signs. Personnel entering the anti-static work area must strictly follow the anti-static work specifications. Also known as ESD (ESD controlled area).
In the field of production, assembly, and maintenance of conventional electronic equipment, various static electricity generating materials and electric fields generated by them are common phenomena, and these static electricity generating materials and electric fields generated therefrom may cause damage to electrostatic sensitive devices. Therefore, the electrostatic sensitive device should be protected throughout its use.
Conductive containers with shielding properties provide the necessary protection during storage and transfer of electrostatically sensitive devices. However, there are also operations outside the shielding container for electrostatically sensitive devices. In this case, the electrostatically sensitive device is very susceptible to damage, so it is necessary to provide a safe working area. The Antistatic Work Area (EPA) is designed for this purpose. In order to ensure the anti-static safety of the workbench, it must meet the following requirements:
(1) All electronic components in the anti-static area should be treated as static sensitive devices.
(2) Operation of any static sensitive device outside the protected state (outside the Faraday cage) must be performed in an antistatic work area.
(3) Electrostatic sensitive devices that are transported in non-antistatic areas between the antistatic work areas must be in a safe state of protection.
(4) The anti-static work area should be designed to ensure that the electrostatically sensitive components are not easily accessible to the metal grounded enclosure of the instrument.
(5) It is forbidden to place static electricity generating materials that are not necessary for work in the anti-static work area, such as plastic bags, boxes, foams, tapes, notebooks, paper sheets, personal items, etc. that are not treated with antistatic. These materials must be separated from the static sensitive devices. More than a centimeter.
(6) All auxiliary materials such as detergents, solvents, coating materials, aerosols, etc. used on the workbench must be approved by the person in charge of static electricity control.
