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:
All personnel who handle or even just come into contact with
ESD sensitive items most have initial and recurrent ESD awareness and
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
Mark ESDS items in accordance with other customer contracts,
purchase orders, drawings or other documentation.
