Table 1-1 ESD precautions
Item Precaution
Wrist strap Wear an antistatic wrist strap when handling printed boards and
components containing electronic components.
ESD mat An approved ESD mat provides protection from static damage
when used with a wrist strap. The mat also acts as a cushion to
protect the small parts that are attached to printed boards.
Antistatic bag/
ESD safe packaging box
After removing a printed board or component, place it in the
antistatic bag or ESD safe packaging box.
Caution
- Do not connect the wrist strap clip to the ESD mat. By connecting the wrist
strap clip to the chassis, the operator and components have the same electrical
potential, thus eliminating the danger of static damage.

How to use a wrist strap
