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 alified
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 ovide an intelli ge nt 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 ative tec hnical research. 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.
