What is an LRU
Line Replaceable Unit
What percentage of ESD problems cause only partial failure?
80-90%
What are the common factors that contribute to static electricity
- Humidity
- Temperature
- Type of material
- Form of movement
What voltage can cause damage to ESDs
Voltages as low as 100v
What is static electricity
The exchange of atomic electrons between two materials
How does the material affect the affect of static electricity
- Effect very low in conductive materials
- Very high in non conductive materials
How should ESD devices be stored and transported
In anti-static materials
How should you clean ESD components
With natural-bristle brushes
If an ESD is damaged, can it be repaired
It can rarely be repaired, especially in large scale integrated circuits which are common on advanced circuit boards
What must you do before removing an LRU or an ESD
Turn off power
