ESD

The nature of electricity was revealed in Chapter 00000. In the PC, the non-motor components operate at 5 Volts or less.

The smallest amount of static you can feel (as you touch a grounded object) has about 30,000 Volts. An electronic component such as an IC doesn't stand a chance of living if it is subjected to a charge of that dimension. Static does not have to be at the level you can feel to kill an electronic component. Any time static electricity is released it is called Electro Static Discharge (ESD).

Static Alert

The probability of creating static is highest with cold temperatures and low humidity.


Because electronic components are sensitive to ESD, they arrive in anti-static bags. Never remove an electronic part from this bag until you are wearing an anti-static strap that is attached to ground. The work area should have an anti-static mat that is attached to ground.

Grounding Strap

Anti-static strap should be worn and attached to ground before removing any components.
