GN Series Hardware Manual 1.3 Electrostatic Discharge (ESD)51.3 Electrostatic Discharge (ESD)A sudden discharge of electrostatic electricity can destroy static-sensitive devices ormicro-circuitry. Proper packaging and grounding techniques are necessary prerequisites foravoiding 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-freestation.• Always be properly grounded when touching a sensitive printed-circuit board,component, or assembly.• Store electrostatic-sensitive printed-circuit boards in protective packaging or onconductive foam.1.3.1 Grounding MethodsGuard against electrostatic damage of the device by taking the following preventative steps:• Cover workstations with approved anti-static material. Provide a wrist strap connectedto 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 theedge of the board.• Avoid contact with pins, leads, or circuitry.• Turn off power and input signals before inserting and removing connectors or testequipment.• Keep the work area free of non-conductive materials such as ordinary plasticassembly aids and Styrofoam.• Use field service tools, such as cutters, screwdrivers, and vacuum cleaners that areconductive.• Always lay drives and PCBs with the component-side down on the foam.
