Electronic product anti-static facilities
1. Static safety workbench
a. The electrostatic safety workbench is an essential part of the anti-static work area. It consists of a workbench, an anti-static table mat, a wristband joint, and a grounding wire.
b. There should be no less than two wristband connectors on the anti-static table mat, one for the operator and the other for the technician, the inspector or other personnel.
c. If necessary, the electrostatic safety workbench should be equipped with an ion wind static eliminator.
d. It is not allowed to stack plastic boxes (sheets), rubber, cardboard, glass and other debris that are easy to generate static electricity on the static safety workbench. The drawings and materials should be placed in the anti-static paper bag.
2, anti-static wrist strap
Persons who are in direct contact with electrostatic sensitive devices should wear anti-static wristbands. The wristbands should have good contact with human skin. The wristbands must be non-irritating and non-allergic to the human body. The resistance of the wristband system to ground should be in the range of 106 to 108 Ω. Inside.
3, anti-static container
In the development and production of electronic equipment, all storage and turnover SSD containers (component bags, transfer boxes, printed boards, component storage boxes, etc.) should have electrostatic protection. Metal and ordinary plastic containers are not allowed. If necessary, the tote box for the storage unit should be grounded.
4, ion wind static eliminator
An ion wind static eliminator should be used to eliminate the static charge on the surface of the insulating material.
5, anti-static overalls
a. Persons entering the anti-static work area or contacting the SSD should wear anti-static overalls. The anti-static overalls fabrics should meet the requirements of GB 12014.
b. In an environment with a relative humidity greater than 50%, the anti-static overalls are allowed to use pure cotton products.
6, anti-static work shoes
Persons entering the anti-static work area or contacting the SSD should wear anti-static work shoes. The anti-static work shoes should comply with the relevant provisions of GB 4385. Normal shoes are generally allowed, but a conductive shoe bundle or heel strap should be used at the same time.
7, anti-static transport vehicle
When transporting SSDs or integral parts containing SSD, use a transport vehicle with antistatic properties.
