9. Prevention of Electro Static Discharge (ESD) to
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by electricity. Such
components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical
ES devices are integrated circuits and some field-effect transistorsand semiconductor “chip”
components. The following techniques should be used to help reduce the incidence of
component damage caused by electro static discharge (ESD).
1. Immediately before handling any semiconductor component or
semiconductor-equiped assembly, drain off any ESD on your
body by touching a known earth ground. Alternatively, obtain and
wear a commercially available discharging ESD wrist strap,
whichshould be removed for potential shock reasons prior to
applying power to the unit under test.
2. After removing an electrical assembly equiped with ES devices,
place the assembly on a conductive surface such as aluminium
foil, to prevent electrostatic charge build up or exposure of the
assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES
