Wear the ESD uniform, ESD gloves, and ESD shoes before entering the equipment
room.
Locate the equipment room far away from areas with dense corrosive gases, such as
chemical plants.
The air intake vent of the equipment room must not face any pollution source.
Place batteries in a different room from the devices.
Invite professionals to measure the temperature, humidity, and other factors periodically.
Provide operators with ESD protection training.
Adjust the humidity to reduce the impact of static electricity.
Install an ESD floor in the equipment room.
Wear an antistatic suit, ESD gloves, and antistatic shoes before entering the equipment
room.
Use ESD tools, such as ESD wrist straps, ESD tweezers, and extractors.
All the conductors in the equipment room, including computer terminals, must be
properly grounded. Set up an antistatic workbench.
Electrostatic sources, such as non-ESD plastic bags, non-ESD foam, and rubber objects
must be kept at least 30 cm away from ESD-sensitive components and boards.
Ensure that the USG is properly grounded according to the grounding requirements.
Wear an ESD wrist strap before performing any operations on the USG.
Ensure proper contact between the metal buckle of the ESD wrist strap and the operator's
skin. Ensure that the other end of the ESD wrist strap is already connected to the ESD
