Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some ﬁeld-effect transistors and
semiconductor „chip” components. The following techniques should be used to help reduce the incidence of component damage
caused by electro static discharge (ESD).
body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap,
which should be removed for potential shock reasons prior to applying power to the unit under test.

replacement ES devices are packaged with leads electrically shorted together by conductive foam, alminum foil or comparable
to the chassis or circuit assembly into which the device will be installed.
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
