S 20.20 is standard that spells out the administrative
and technical requirements necessary to design, establish,
implement, and maintain an Electrostatic Discharge (ESD)
Control Program for activities that : manufacture, process,
assemble, install, package, label, service, test, inspector
otherwise handle electrical, electronic parts, assemblies
and equipment susceptible to damage by ESD greater than
or equal to 100 volts Human Body Model (HBM). The standard
also does not apply to electrically initiated explosive
devices, flammable liquids and powders.
ANSI/ESD S 20.20 is standard developed by the ESD association
and approved by ANSI. The ESD Association is a professional
voluntary association dedicated to advancing the theory
and practice of electrostatic discharge (ESD) avoidance.
It was founded in 1982 in the United States and has
a strong international flavour with members from more
than 30 countries throughout the world. The association
is chartered to expand ESD awareness through standards
development, educational programs, local chapters, publications,
tutorials, certification, and symposia.
ESD Association Standards can be purchased from the
Association headquarter at 7900 Turin Road, Bldg 3,
Suite 2, Rome, New York NY 13440-2069. Tel: 315-339-6937.

PSB Certification Pte Ltd successfully completed the
ANSI/ESD S 20.20 witness assessment at Amkor Technology
Singapore Pte Ltd on 24 Mar 2005 and has been approved
by the ESD Association as an S20.20 certified registrar.
FREQUENTLY ASKED QUESTIONS FOR ANSI/ESD S20.20
1) WHAT IS ESD ?
ESD stands for Electrostatic Discharge. It is a transfer
of electrostatic charges between bodies at different
electrostatic potentials caused by direct contact or
induced by an electrostatic field.
2) WHAT IS THE ESD ASSOCIATION ?
It is a professional voluntary association dedicated
to advancing the theory and practice of electrostatic
discharge (ESD) avoidance. It was founded in 1982. Although,
it is founded and headquartered in the United States,
the ESD association has a strong international flavour
with members from more than 30 countries throughout
the world. The association is chartered to expand ESD
awareness through standards development, educational
programs, local chapters, publications, tutorials, certification,
and symposia.
3) WHAT IS THE ANSI/ESD S20.20 STANDARD ?
It is a standard developed by the ESD association.
It covers the requirements necessary to design, establish,
implement, and maintain an Electrostatic Discharge (ESD)
Control Program for activities that : manufacture, process,
assemble, install, package, label, service, test, inspector
otherwise handle electrical, electronic parts, assemblies
and equipment susceptible to damage by ESD greater than
or equal to 100 volts Human Body Model (HBM).
For devices susceptible to less than 100 volts HBM,
more stringent ESD Control Program Technical Requirements
may be required, including adjustment of program Technical
Element Recommended Ranges.
The standard also does not apply to electrically initiated
explosive devices, flammable liquids and powders.
4) WHERE DO I OBTAIN COPIES OF THE ESD ASSOCIATION
STANDARDS ?
ESD Association Standards can be purchased from Association
headquarters, 7900 Turin Road, Bldg 3, Suite 2, Rome,
New York NY 13440-2069. Tel: 315-339-6937 or www.esda.org.
5) HOW DO I FIND THE ESD SENSITIVITY INFORMATION FOR
SPECIFIC ESDS COMPONENTS ?
The first source would be the manufacturer or supplier
of the component. An additional source is IIT Research
Institute/ Reliability Analysis Centre in Rome, NY.
The organisation issues a publication VZAP-95, Electrostatic
Discharge Susceptibility Data for 22,000 devices.
6) IF MY COMPANY IS NOT CERTIFIED TO ISO 9001:2000,
CAN I GO FOR ANSI/ESD S20.20 CERTIFICATION ?
Yes. Certification man-days would be more than a company
which is ISO 9001:2000 certified. The additional man-days
are to cover ISO 9001:2000 clauses like Quality System,
Document and Data Control, Control of inspection, measuring
and test equipment, Control of non-conforming product;
Corrective and preventive action.
7) IF MY COMPANY HAS SUB-CONTRACTORS WHO HANDLE MY
ESDS ITEMS/DEVICES, WOULD THEY BE INVOLVED IN THE CERTIFICATION
ASSESSMENT ?
YES. As long as your subcontractors handle your ESDS
items and these items eventually are delivered to your
customers, PSB Certification assessors would need to
audit the sites of your subcontractors to verify that
their ESD controls are adequate.
8) WHAT IS THE CERTIFICATION PACKAGE FOR ANSI/ESD S20.20
?
The one-time certification package comprises of the
following :
(i) Manual assessment
(ii) Preliminary assessment (OPTIONAL)
(iii) Certification assessment
9) WHAT IS THE TYPICAL COST OF ANSI/ESD S20.20 CERTIFICATION
?
The cost of certification varies, depending on a number
of factors such as the size of the company and the number
of sub-contractors who handle your ESDS devices/items.
Please submit the registration form and we will give
you a quotation.
10) WHAT ARE THE ADVANTAGES OF USING PSB CERTIFICATION
FOR ANSI/ESD S20.20 CERTIFICATION ?
We have a team of competent and professional assessors
capable of performing integrated quality management
system audits eg. TS 16949, TL 9000 and ISO 14000 together
with the ANSI/ESD S20.20 assessments.
