The connection method of the grounding trunk line should be brazed

The connecting terminals of the anti-static equipment should ensure reliable contact and easy to assemble and disassemble. It is allowed to use various clip-type connecting aluminum, such as fish clip, plug socket, etc.

Ceiling material

Ceiling materials should be made of antistatic materials. Generally, gypsum board products are allowed, and ordinary plastic products are prohibited.

Wall fabric

Antistatic wallpaper should be used for wall fabrics. In general, plaster paint or lime paint is allowed for walls, and ordinary wallpaper and plastic wallpaper are prohibited.

Humidity control

The relative humidity of the anti-static work area should not be less than 50%.

Under the premise of not causing harmful effects on the product, it is allowed to use humidifying equipment to spray formulations or water to increase the environmental humidity.

The humidity of the computer room should meet the relevant regulations in GB 2887, and similar computer rooms should also comply with this regulation.

Regional boundaries

The anti-static work area should be marked with regional boundaries, and warning signs should be hung at obvious places. The warning signs should comply with the GJB 1649 regulations. The entrance of the work area should be equipped with ionized air wind bath equipment.

Charge source

It is forbidden to use and touch charge sources that are prone to generate static charges in the antistatic work area.

Anti-static facilities

Electrostatic safety workbench

The electrostatic safety workbench is the basic part of the anti-static work area. It consists of a workbench, an anti-static table mat, a wrist strap connector, and a ground wire.

There should be no less than two wrist strap joints on the anti-static table mat, one for operators and the other for technicians, inspectors or other personnel.

When necessary, an ion wind static eliminator should be equipped on the static safety workbench.

Plastic boxes (sheets), rubber, cardboard, glass and other debris that are prone to static electricity are not allowed to be stacked on the electrostatic safety workbench. Drawings and materials should be placed in an anti-static document bag.

Anti-static wrist strap

Anyone who directly touches electrostatic sensitive devices should wear an anti-static wrist strap. The wrist strap should be in good contact with the human skin. The wrist strap must be non-irritating or allergic to the human body. The resistance value of the wrist strap system to ground should be 106～108 ohms. Within the scope.

Anti-static container

In the development and production process of electronic equipment, all storage and turnover SSD containers (component bags, transfer boxes, printed board racks, component storage boxes, etc.) should have electrostatic protection performance. Metal and ordinary plastic containers are not allowed. When necessary, the turnover box for storing components should be grounded.

Ion wind static eliminator

Ion wind static eliminator should be used to eliminate static charge on the surface of insulating material.

Anti-static work clothes

Enter the anti-static work area or touch the SSD. The personnel should wear anti-static overalls, and the fabric of anti-static overalls should meet the requirements of GBl2014.

In an environment with a relative humidity greater than 50%, pure cotton products are allowed for anti-static work clothes.

Anti-static work shoes

People who enter the anti-static work area or come into contact with SSD should wear anti-static work shoes, which should comply with the relevant regulations of GB: 4385. Normal shoes are allowed to wear, but conductive shoe bundles or heel straps should be used at the same time.

Anti-static transport vehicles When transporting SSDs or the entire parts and components containing SSDs, transport vehicles with anti-static properties should be used.
