  • Eight Steps For Being S20.20 Compliant

    For all of our ESD prevention, assessment and detection
    products, you’ll find a feature in the description that states something like
    this: “Meets ANSI/ESD S20.20…” or “In accordance with ANSI/ESD S20.20…” What does
    this mean, exactly? In order to meet the need for standard level products in
    the electronics industry, the ESD Association established the ANSI/ESD S20.20,
    which helps organizations design, implement and maintain an ESD program to
    protect all ESD-sensitive electrical parts, assemblies and equipment. There are
    eight steps to follow in order to become S20.20 compliant, and we’ll go over
    each one of them:

    1. Training

    All personnel who handle or even just come into contact with
    ESD sensitive items most have initial and recurrent ESD awareness and
    prevention training.

    2. Product Qualification

    This is conducted during the initial selection of ESD
    control items to ensure that all of the chosen ESD control items meet the plan
    requirements. This list of these items should be included on your ESD Control
    Plan, a controlled document approved by upper management.

    3. Compliance Verification

    The compliance verification plan identifies electrical
    properties needing checked, measurement limits, and test frequencies per
    manufacturer and industry recommendations.

    4. Grounding/Equipotential Bonding Systems

    In this step, you connect ESDS items, personnel and other
    conductors to the same electrical potential. The 3rd-wire AC
    electrical equipment ground is the preferred, recommended ground reference.

    5. Personnel Grounding

    The two options for grounding here are either wrist straps
    or heel grounders. If person will be seated, wrist straps must be the product
    of choice. A flooring system must also be installed if heel grounders are used.

    6. ESD Protected Area (EPA) Requirements

    You must handle ESDS items, parts, assemblies and equipment
    without ESD protective packaging in an EPA Protected Area with clear
    boundaries. The plans for these must evolve to keep pace with costs, device sensitivities
    and the way they are manufactured.

    7. Packaging Systems

    Define ESD protective packing requirements for both inside
    and outside the EPA. When you are moving ESD susceptible devices outside the
    protected area, you must package and enclose the device in an ESD shielding
    bag.

    8. Marking

    Mark ESDS items in accordance with other customer contracts,
    purchase orders, drawings or other documentation.
