4.4 Preventing Electrostatic Damage

Many electronic components are sensitive to electrostatic

discharge (ESD). Circuitry design and structure determine the

degree of sensitivity. Networks built into many integrated circuits

provide some protection, but in many cases, the discharge

contains enough power to alter device parameters or melt

silicon junctions.

A sudden discharge of static electricity from a finger or other

conductor can destroy static-sensitive devices or microcircuitry.

Often the spark is neither felt nor heard, but damage occurs.

An electronic device exposed to electrostatic discharge might not

be affected at all and can work perfectly throughout a normal

cycle. Or the device might function normally for a while, then

degrade in the internal layers, reducing its life expectancy.
