Because of a need for technical informa-

tion, and to develop standards in the ﬁeld

of printed wiring, the IPC was organized

in 1957 by independent producers of

PWBs and began as The Institute of

Printed Circuits.

The IPC continued to grow and expanded

into areas besides PWBs, thus making it

essential to include other aspects of the

industry. The IPC officially changed its

name in 1977 to The Institute for Inter-

connecting and Packaging Electronic

Circuits to reﬂect the range of products

associated with electronic interconnec-

tions.

The IPC has since further expanded its

horizons and has become involved with

ﬂat cable, ﬂexible circuits, connectors,

discrete wiring, hybrid circuits, and

assembly services.

Yet to this day, the IPC is a not-for-proﬁt

organization dedicated to the technologi-

cal advancement of the printed wiring

industry.

The programs of the IPC are made pos-

sible only through the active, voluntary

support of its membership. The member-

ship of the IPC is made up of representa-

tives of companies from a broad cross-

se ct io n of ind ustry and qu aliﬁe d

technical experts from government agen-

cies, colleges, and universities. Member-

ship in the IPC is on a company basis,

with members being companies that pro-

duce printed wiring boards for sale or

internal use, or suppliers of material or

equipment used in the industry. As a

result of this broad cross-section, the

technical information and documents

published by the IPC reﬂect the consen-

sus of all segments of the industry.

Following are the speciﬁc types of pro-

grams undertaken by the IPC:

1) Through the IPC, the industry devel-

ops and publishes standards and

speciﬁcations to establish common

terminology and promote optimum

application, minimize confusion, and

pr o vide an intelligent path to

productivity.

2) The IPC sponsors seminars and tech-

nical workshops to enable all seg-

ments of the industry to study new

ideas in the technology.

3) The IPC, in its monthly member

magazine, the IPC Review, provides

the industry with news on the IPC

programs and technical standards.

4) The IPC provides a forum for coop-

er a tive tec h n i c a l resear ch. A n

example: A Round Robin to study

board solderability, in which members

would voluntarily submit or sample

test boards. The test results can then

be made available to the entire

industry.

5) The IPC publishes several manuals

and handbooks containing major tech-

nical documentation on key aspects of

our technology, including standards,

technical reports, and guidelines. All

manuals and handbooks are devel-

oped through the cooperative and vol-

untary efforts of the membership.

6) Through the exchange of ideas at

various sessions of our 150 different

committee, subcommittee, or task

groups, as well as by attending the

IPC semiannual meetings, where over

70 new technical papers are pre-

sented, you can better keep your ﬁn-

ger on the pulse of new developments

in the industry.

Because the IPC programs are under-

taken on a voluntary basis and shared by

all in the industry, member companies

have saved millions of dollars that would

have been required for each company to

duplicate that effort. This voluntary

exchange of technical information has

been an important factor in the high pro-

ductivity of the industry.

The IPC Test Methods Manual, IPC-TM-

650, typiﬁes the objectives of the IPC.

The IPC-TM-650 provides useful infor-

mation to designers and users of printed

wiring boards to help with problems they

may encounter in the application of

printed wiring test methods.

The purpose of the IPC-TM-650 is to

keep you abreast on industry-approved

test techniques and procedures for chemi-

cal, mechanical, electrical, and environ-

mental tests on all forms of printed wir-

ing and connectors.

The IPC maintains a list of the individu-

als who have purchased a copy of the

IPC-TM-650. As new material is devel-

oped by our technical committees, all

IPC-TM-650 holders who remain part of

our updating service will be sent the

material for inclusion in their manual.

The scope of this manual is broad. Refer

to the Table of Contents, which speciﬁes

the material now included in the IPC-

TM-650. The IPC-TM-650 is a living

document in that the IPC, through the

input of various technical committees

and individual efforts of technical

experts, will continue to develop and

revise data so that the manual stays cur-

rent.

With the continued voluntary, coopera-

tive activity of the membership, it is

anticipated that, through the IPC, we can

undertake programs and activities which

will be of mutual beneﬁt to representa-

tives from both the printed wiring and

electronics industries. The IPC will pro-

vide a forum through which the objec-

tives of the industry can be attained with

the greatest efficiency and economy.

IPC-TM-650

The IPC Test Methods Manual, IPC-TM-650, is divided into several major sections to provide a systematic means of

displaying a variety of information pertinent to testing all types of printed circuits and connectors. The following is a

general description of the information contained in each major section of the IPC-TM-600. A more detailed listing of

the contents of each major section appears as the Table of Contents at the beginning of each major section.

Section One contains a listing of the Test Methods Subcommittee members, an explanation of the use of this volume,

information of general interest relative to calibration of test equipment, reporting formats and practices, organizational

abbreviations and sources, compliance certiﬁcation, and review board procedures.

Section Two contains the speciﬁc test methods, together with appropriate illustrations, sketches, and tables necessary

for the performance of chemical, mechanical, electrical, and environmental tests on all forms of printed circuits. It is

divided into subsections so that each test method can be found easily under the broad titles mentioned above. These

test methods are also intended for use by adapting them for testing materials or end products similar to those for which

these test methods were speciﬁcally written.

Section Three contains the speciﬁc test methods, together with appropriate illustrations, sketches, and tables necessary

for the performance of chemical, mechanical, electrical, and environmental tests on connectors used in printed cir-

cuitry. These test methods are abstracted from the EIA-IPC agreed upon test methods appearing in the EIA-RS-364

Standard.

Section Four contains information on diagnostic techniques for failure analyses. These are not standard test methods

because the methods and procedures vary, depending on the condition or behavior of the test specimen. This section

is intended to provide a feel for the capabilities of diagnostic testing for the relatively sophisticated equipment and

training required, as well as the cost of diagnostic analyses. Most of these analytical test techniques are not feasible

for routine incoming inspection, in-process inspection, or end-product evaluation.

Section Five contains related information to supplement and support the previous sections. It provides a listing of

related test methods that may be utilized even though not yet officially concurred with by the IPC, a listing of related

publications, a subsection dedicated to the metric system, information on preparing samples for testing, and speciﬁ-

cations and sketches of test pattern artwork for all forms of printed circuitry.
