4.1. Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or micro-circuitry.
Therefore proper packaging and grounding techniques are necessary precautions to prevent damage.
Always take the following precautions:
1. Transport boards in ESD-safe containers such as boxes or bags.
2. Keep electrostatic sensitive parts in their containers until they arrive at the ESD-safe workplace.
3. Always be properly grounded when touching a sensitive board, component, or assembly.
4. Store electrostatic-sensitive boards in protective packaging or on antistatic mats.
4.1.1. Grounding Methods
The following measures help to avoid electrostatic damages to the device:
1. Cover workstations with approved antistatic material. Always wear a wrist strap connected to
workplace as well as properly grounded tools and equipment.
2. Use antistatic mats, heel straps, or air ionizers for more protection.
3. Always handle electrostatic sensitive components by their edge or by their casing.
4. Avoid contact with pins, leads, or circuitry.
5. Turn off power and input signals before inserting and removing connectors or connecting test
equipment.
6. Keep work area free of non-conductive materials such as ordinary plastic assembly aids and styrofoam.
7. Use field service tools such as cutters, screwdrivers, and vacuum cleaners which are conductive.
8. Always place drives and boards PCB-assembly-side down on the foam.
