Ensure good contact of the metal tab of the wrist strap with your bare skin. Insert the other
end of the wrist strap into the grounding point on the device.
Ensure that the wrist strap works in the normal state. Its resistance value must be between
0.75 megohm and 10 megohm. If the service life (usually two years) of the wrist strap
expires or the resistance value fails to meet requirements, replace it with another one.
Avoid touching the board with your clothes, because the touch generates static electricity
that is beyond the protection scope of the wrist strap.
Wear antistatic gloves and place the board on an antistatic pad when replacing the chip of
the board. Use antistatic tweezers or extraction tools to replace chips. Do not tough chips,
circuits, or pins with your bare hands.
Keep the board and other ESD sensitive parts to be installed in antistatic bags. Place the
removed boards and components on an antistatic pad or other antistatic materials. Do not
use non-antistatic materials such as white foams, common plastic bags, or paper bags to
pack boards or let them touch boards.
Wear an antistatic wrist strap when operating the ports of boards because they are also
ESD-sensitive. Discharge the static electricity of cables and protective sleeves before
connecting them to the ports.
It is recommended that you reserve some materials that can hold boards such as vacuum
formed boxes and antistatic bags in the equipment room for later use.
