1.3 Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or
micro-circuitry. Proper packaging and grounding techniques are necessary prerequisites for
avoiding damage. Always take the following precautions:
•
Transport printed circuit boards in static-safe containers such as boxes or bags.
•
Keep electrostatic sensitive parts in their containers until they arrive at a static-free
station.
•
Always be properly grounded when touching a sensitive printed-circuit board,
component, or assembly.
•
Store electrostatic-sensitive printed-circuit boards in protective packaging or on
conductive foam.
1.3.1 Grounding Methods
Guard against electrostatic damage of the device by taking the following preventative steps:
•
Cover workstations with approved anti-static material. Provide a wrist strap connected
to a work surface and properly grounded tools and equipment.
•
Use anti-static mats, heel straps, or air ionizers for added protection.
•
Handle electrostatic-sensitive components, PCBs, and assemblies by the case or the
edge of the board.
•
Avoid contact with pins, leads, or circuitry.
•
Turn off power and input signals before inserting and removing connectors or test
equipment.
•
Keep the work area free of non-conductive materials such as ordinary plastic
assembly aids and Styrofoam.
•
Use field service tools, such as cutters, screwdrivers, and vacuum cleaners that are
conductive.
•
Always lay drives and PCBs with the component-side down on the foam.
