Such components com- monly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated cir - cuits 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 static electricity . 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly , drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive sur - face such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly . 3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices. 4. Use only an anti-static sol
