Drive handling 30
A discharge of static electricity from a finger or other conductor can destroy static sensitive devices or microcircuitry even if the spark is neither felt nor heard damage may have occurred 31
An electronic device exposed to esd may not be affected at all and can work perfectly throughout a normal cycle or the device may function normally for a while then degrade in the internal layers reducing its life expectancy 31
Avoid touching pins leads and circuitry handle electronic components as little as possible 31
Before touching an electronic component discharge static electricity by using the guidelines described in this section 31
Caution a product can be degraded by as little as 700 v 31
Caution to prevent damage to the computer when you are removing or installing internal components observe these precautions 31
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 esd contains enough power to alter device parameters or melt silicon junctions 31
