3.2.7 Electrostatic Discharge
The static electricity generated by the human body may damage the electrostatic sensitive
components on the circuit board, such as the large-scale integrated circuit (LSI).
In the following situations, the human body will generate a static electromagnetic field:
l
Human body moving
l
Clothes friction
l
Friction between shoes and the ground
l
Holding ordinary plastic in hand
The static electromagnetic field will remain within the human body for a long time.
Before touching the device, hand-operating parts, circuit boards, or ASICs, wear a grounded
electrostatic discharge (ESD) wrist strap. It can prevent the sensitive components from
damage by the static electricity in the human body.
