IPC TEST METHODS MANUAL

FOREWORD

The purpose of this test methods manual is to contain, in one document, pertinent information on test methods that

will be useful to manufacturers and users of printed boards, electronic assemblies, hybrid circuits, discrete wiring, and

ﬂat cable. It provides an organized reference source for test methods, which can be utilized by the testing laboratories

of manufacturers and users of products of the electronic interconnection industry. In addition, this document provides

an organized reference source of test methods that can be utilized by the technical committees of the IPC, in their work

to develop new standards and speciﬁcations.

TELLS HOW TO TEST — NOT REQUIREMENTS FOR ACCEPTANCE

This test methods manual is designed to provide speciﬁc information on test methods. It does not attempt to establish

acceptability levels for performance. Details of performance requirements can be found in appropriate IPC speciﬁca-

tions, which are referenced in the manual.

ABOUT THE TEST METHODS IN THIS MANUAL

Each test method includes a brief description of its purpose and provides a listing of all equipment, apparatus, and

other required materials necessary to perform the speciﬁed procedures. The test method may also include brief men-

tion of limitations and/or speciﬁc areas of non-applicability.

Procedures for performing each test method are detailed in this publication. They include information on speciﬁc con-

ditioning, curing, or other specimen preparation, as well as the speciﬁc procedure for conducting the test. Each pro-

cedure is sufficiently detailed so that the test can be accomplished by a technician familiar with standard laboratory

practices and procedures.

SOURCE OF TEST METHODS IN THIS MANUAL

Most of the test methods published in this manual have been taken from previously approved standards and speciﬁ-

cations of the IPC. Therefore, these test methods have been reviewed and approved by the entire membership of the

IPC. Since the IPC membership represents both manufacturers and users, and since they represent technical represen-

tatives from supplier member companies and technical experts from many government agencies, the standards and

speciﬁcations approved by the IPC have a broad base of acceptance.

In the event of a dispute over details of an IPC test method, the details of the test method published in the individual

IPC standards and speciﬁcations should be considered the governing document.

Other test methods included in this manual have been taken from government standards or other standards that have

extensive use in the electronic interconnection industry.

FUTURE TEST METHODS

The IPC will continue its efforts to maintain an awareness of all new developments in test methods. As new require-

ments for testing are developed, they will be studied by the IPC Test Methods Subcommittee and by other appropri-

ate technical committees of the IPC. Where appropriate, such test methods will be approved and formatted for inclu-

sion in the IPC-TM-650.

With regard to new test methods, the IPC seeks ideas and recommendations from all who are concerned with printed

board and related interconnection products. If you have ideas for new tests that are needed, or information on new

tests that are available for use in our industry, contact the IPC at 3000 Lakeside Drive, Suite 309 S, Bannockburn, IL

60015, Tel 847/615/7100, Fax 847/615/7105.

Introduction

This manual establishes uniform methods for testing electronic

and electrical parts including basic environmental, physical

and electrical tests. These tests were developed to support

IPC standards and specifications.

The tests described herein are not to be interpreted as an

exact and conclusive representation of actual service opera-

tion in any one geographic location, since it is known that the

only true test for operation in a specific location is an actual

service test at that point. The specified test conditions for a

test method are those, which are obtainable in the laboratory

and result in reproducible results.

No attempt has been made to include pass/fail criteria in the

test methods. This information is found in the individual speci-

fications and standards that reference the specific test

method.
