FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC technical committees is to prepare International Standards. However, a

technical committee may propose the publication of a technical report when it has collected

data of a different kind from that which is normally published as an International Standard, for

example "state of the art".

IEC 61340-5-2, which is a technical report, has been prepared by IEC technical committee

101: Electrostatics.

This version cancels and replaces the first edition, which was issued as a technical

specification in 1999. It constitutes a technical revision.

INTRODUCTION

This user guide and has been produced for individuals and organizations that are faced with

controlling electrostatic discharge (ESD). It provides guidance that can be used for

developing, implementing and monitoring an electrostatic discharge control program in

accordance with IEC 61340-5-1.

This user guide applies to activities that: manufacture, process, assemble, install, package,

label, service, test, inspect or otherwise handle electrical or electronic parts, assemblies and

equipment susceptible to damage by electrostatic discharges greater than or equal to 100 V

using the human body model (HBM). The 100 V HBM limit was selected for IEC 61340-5-1 as

the baseline susceptibility threshold, since a large majority of the ESD products on the market

have a sensitivity of greater than 100 V.

The limits established for each of the ESD control items are specified for an ESD program

designed for 100 V HBM devices. The 100 V value is predicated on maximum voltage levels

attainable on an individual when they are grounded via techniques accepted throughout the

electronics industry as outlined in IEC 61340-5-1.

For organizations concerned with charged device model damage, IEC 61340-5-1 establishes

requirements concerning the use of insulators in the ESD protected area (EPA) based on

maximum electrostatic field limits. This topic is addressed in more detail in 4.6.

The general principals described in IEC 61340-5-1 are not limited in their applicability to

ESDS with ESD sensitivities of 100 V or greater. For companies that handle ESDS with

sensitivities of less than 100 V (HBM), the general principals of IEC 61340-5-1 can still be

used. The organization may have to modify some of the required limits specified in Tables 2

to 4. The program documentation would then identify that ESDS with sensitivities of less than

100 V HBM were being handled and that this required a change to the limits established in

IEC 61340-5-1.

The fundamental ESD control principles that form the basis of IEC 61340-5-1 are as follows:

a) Avoid a discharge from any charged, conductive object (personnel, equipment) into the

device:

This can be accomplished by bonding or electrically connecting all conductors in the

environment, including personnel, to a known ground or contrived ground (as on shipboard

or on aircraft). This attachment creates an equipotential balance between all items and

personnel. Electrostatic protection can be maintained at a potential different from “zero”

voltage ground potential, as long as all items in the system are at the same potential.

b) Avoid a discharge from any charged ESD sensitive device (the charging can result from

direct contact and separation or can be field induced):

Necessary insulators in the environment cannot lose their electrostatic charge by

attachment to ground. Ionization systems provide neutralization of charges on these

necessary insulators (circuit board materials and some device packages are examples of

necessary insulators). Assessment of the ESD hazard created by electrostatic charges on

the necessary insulators in the work place is required to ensure that appropriate actions

are implemented, according to the risk.

c) Once outside of an electrostatic discharge protected area (hereafter referred to as an

EPA) it is often not possible to control the above items, therefore, ESD protective

packaging may be required.

ESD protection can be achieved by enclosing ESD sensitive products in static protective

materials, although the type of material depends on the situation and destination. Inside

an EPA, low charging and static dissipative materials may provide adequate protection.

Outside an EPA, low charging and static discharge shielding materials are recommended.

While all of these materials are not discussed in this standard, it is important to recognize

the differences in their application.

1 Scope
This technical report has been developed to support IEC 61340-5-1.

The controls and limits referenced in this standard were developed to protect devices that are

susceptible to discharges of 100 V or greater using the human body model test method.

However, the general concepts are still valid for devices that are susceptible to discharges of

less than 100 V.

3 Terms and definitions

For the purposes of this document, the terms and definitions of IEC 61340-5-1 apply.

4 ESD control program plan

This clause outlines a step-by-step approach that can be used to establish an ESD control

Program.
4.1 Developing an ESD control program plan
4.1.1 Assignment of an ESD coordinator

In order to have a well thought out and implemented ESD program an ESD coordinator must

be assigned. The ESD coordinator is responsible for all aspects of ESD in the facility. In order

to be effective the ESD coordinator needs:
a) the full support of management;

b) a good understanding of electrostatics and how ESD sensitive devices can be damaged.

The ESD coordinator will often need to attend educational classes or seminars related to

ESD in order to maintain or update their knowledge;

c) a thorough understanding of IEC 61340-5-1 and all of the organization’s processes related

to the handling of ESD sensitive devices.

d) access to measuring equipment for the purposes of performing compliance verification

audits as well as testing new ESD products and materials for use in the ESD program;

e) depending on the size of the facility, the ESD coordinator might also need to have auditors

assigned to conduct the ESD audits.

Finally, management must provide the ESD coordinator with the authority and funding

necessary to ensure that the ESD control program is maintained and enforced.
4.1.2 Determination of part ESD sensitivity

The next step in developing an ESD control program plan is to determine the part, assembly

or equipment sensitivity level under which the plan is to be developed. Although the

requirements outlined in IEC 61340-5-1 are effective fo
