Electrostatic Charge
Electrostatic charge phenomena may occur in the human body which is not connected
to surrounding electrical level.
The following data shows the maximum electrostatic voltage which may be generated
when human body contacts specified material. These values are compliant with IEC
801-2 specifications.
Electrostatic voltage on the body of operating personnel
Basic protective measures to prevent ESD:
Ensure excellent equipotential connection:
When holding the ESD-sensitive device, please make sure your body, work area and
package are grounded. This can prevent electrostatic charge.
Avoid direct contact:
Usually, people only contact ESD-sensitive device in unavoidable circumstances (for
example, for repair). When holding the module, do not touch any chip pin or PCB
circuit. In this way, the dissipated electricity will not affect the ESD-sensitive device.
Before handling the module, dissipate the electrostatic charges on your body. They
can be dissipated by contacting grounded metal part. Make sure to use grounded
measuring instrument.
