QUALIFICATION AND PERFORMANCE SPECIFICATION OF PERMANENT
SOLDER MASK AND FLEXIBLE COVER MATERIALS
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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC PAS 61249-8-5, submitted by IPC has been processed by IEC technical committee 91:
Electronics assembly technology. It is based on IPC-SM-840E. It is published as a double-
logo PAS. The structure and editorial rules used in this PAS reflect the practice of the
organization which submitted it.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
91/1157/PAS 91/1174/RVD
Following publication of this PAS, the technical committee or subcommittee concerned may
transform it into an International Standard.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single period up to a maximum of 3 years,
at the end of which it shall be published as another type of normative document, or shall be
withdrawn.

The Principles of
In May 1995 the IPC’s Technical Activities Executive Committee (TAEC) adopted Principles of
Standardization
Standardization as a guiding principle of IPC’s standardization efforts.
Standards Should: Standards Should Not:
Show relationship to Design for ManufacturabilityInhibit innovation
(DFM) and Design for the Environment (DFE)Increase time-to-market
Minimize time to marketKeep people out
Contain simple (simplified) languageIncrease cycle time
Just include spec informationTell you how to make something
Focus on end product performanceContain anything that cannot
Include a feedback system on use and be defended with data
problems for future improvement
Notice IPC Standards and Publications are designed to serve the public interest through eliminating mis-
understandings between manufacturers and purchasers, facilitating interchangeability and improve-
ment of products, and assisting the purchaser in selecting and obtaining with minimum delay the
proper product for his particular need. Existence of such Standards and Publications shall not in
any respect preclude any member or nonmember of IPC from manufacturing or selling products
not conforming to such Standards and Publication, nor shall the existence of such Standards and
Publications preclude their voluntary use by those other than IPC members, whether the standard
is to be used either domestically or internationally.
Recommended Standards and Publications are adopted by IPC without regard to whether their adop-
tion may involve patents on articles, materials, or processes. By such action, IPC does not assume
any liability to any patent owner, nor do they assume any obligation whatever to parties adopting
the Recommended Standard or Publication. Users are also wholly responsible for protecting them-
selves against all claims of liabilities for patent infringement.
IPC Position It is the position of IPC’s Technical Activities Executive Committee that the use and implementation
Statement on
of IPC publications is voluntary and is part of a relationship entered into by customer and supplier.
Specification
When an IPC publication is updated and a new revision is published, it is the opinion of the TAEC
Revision Change
that the use of the new revision as part of an existing relationship is not automatic unless required
by the contract. The TAEC recommends the use of the latest revision. Adopted October 6, 1998

one another better. Standards allow manufacturers greater efficiencies when they can set up their
processes to meet industry standards, allowing them to offer their customers lower costs.
IPC spends hundreds of thousands of dollars annually to support IPC’s volunteers in the standards
and publications development process. There are many rounds of drafts sent out for review and
the committees spend hundreds of hours in review and development. IPC’s staff attends and par-
ticipates in committee activities, typesets and circulates document drafts, and follows all necessary
procedures to qualify for ANSI approval.
IPC’s membership dues have been kept low to allow as many companies as possible to participate.
Therefore, the standards and publications revenue is necessary to complement dues revenue. The
price schedule offers a 50% discount to IPC members. If your company buys IPC standards and
publications, why not take advantage of this and the many other benefits of IPC membership as
well? For more information on membership in IPC, please visit www.ipc.org or call 847/597-2872.
Thank you for your continued support.
