Removal and Replacement Preliminaries 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 life cycle. Or the device might function normally for a while, then degrade in the internal layers, reducing its life expectancy. 4.5 Packaging and Transporting Precautions Use the following grounding precautions when packaging and transporting equipment: ■ To avoid hand contact, transport products in static-safe containers, such as tubes, bags, or boxes. ■ Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging. ■ Keep electrostatic-sensitive parts in their containers until the parts arrive at static-free workstations. ■ Place items on a grounded surface before removing them from their containers. ■ Always be properly grounded when touching a sensitive component or assembly. 4-4 Maintenance and Service Guide
