5.3 Electro Static Discharge (ESD)
CAUTION!
All types of electronic components, particularly integrated circuits, are in some
way sensitive to Electro Static Discharge (ESD). Damage caused by ESD is a
common reason for faults in electronic equipment.
The total operating time between failures can be extended considerably by
avoiding ESD damage during installation and maintenance work. This has
become more important as electronic components decrease in size and increase
in sensitivity.
The following ESD basic rules have to be followed when working with
electronic components.
• Avoid materials or clothes that easily create electrostatic charges.
• Retain spare parts in their transport packaging until just before use.
• Ensure that PCBs (Printed Circuit Boards) are correctly packed.
• Do not slide PCBs over any surface.
• Always wear a wrist strap connected to ground when handling PCBs.
• Not all components carry ESD warning labels. Nevertheless, always treat
electronic components and units as if they were sensitive to electrostatic
discharge.
