Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive
devices.
Proper packaging and grounding techniques are necessary precautions to prevent
damage. Always take the following precautions:
Transport ESD-sensitive products in ESD-safe containers such as boxes or bags.
Keep electrostatic sensitive parts in their containers until they arrive at the ESD-
safe workplace.
Always be properly grounded when touching sensitive products, components, or
assembly.
Store electrostatic-sensitive products in protective packaging or on antistatic mats.

Grounding Methods
To avoid electrostatic damage, observe the following grounding guidelines:
Cover workstations with approved antistatic material. Always wear a wrist strap
connected to the workplace. Always use properly grounded tools and equipment.
Use antistatic mats, antistatic wristband, heel straps, or air ionizers for more
protection.
Always handle electrostatically sensitive components by their edge or by their
casing.
Avoid contact with pins, leads, or circuitry.
Switch off power and input signals before inserting and removing connectors or
connecting test equipment.
Keep work area free of non-conductive materials such as ordinary plastic assembly
aids and Styrofoam.
Use only field service tools that are conductive, such as cutters, screwdrivers, and
vacuum cleaners.
Always place any boards PCB-assembly-side down on a grounded conductive base
Protective Grounding
The protective grounding provides a secure connection to the ground potential to
protect against dangerously high touch voltages in the event of a malfunction.
Risk of electric shock through contact with live wires!
Only personnel with proper qualifications or qualified electricians should perform work
on the low-voltage network (<1000 VAC) and all work must comply with the
national/local requirements for electrical connections.
