Surface mounting technology - Environmental and endurance test methods for surface mount solder joint -- Part 1-2: Shear strength test

The test method described in this part of IEC 62137 is applicable to leadless surface mounting components and surface mounting connectors to which pull test is not applicable. It is not applicable to multi-lead components and gull-wing leads. The method is designed to test and evaluate the endurance of the solder joint between component terminals and lands on a substrate, by means of a shear type mechanical stress. This test is applicable to evaluate the effects of repeated temperature change on the strength of the solder joints between terminals and lands on a substrate.

La méthode d'essai décrite dans la CEI 62137-1-2:2007 est applicable aux composants montés en surface sans connexion et aux connecteurs montés en surface auxquels l'essai à la traction n'est pas applicable. Elle n'est pas applicable aux composants à sorties multiples ni aux composants à sortie en aile de mouette. La méthode est conçue pour soumettre à essai et évaluer l'endurance du joint brasé entre les bornes des composants et les plages d'accueil sur un substrat, au moyen d'une contrainte mécanique de type cisaillement. Cet essai permet d'évaluer les effets de variations répétées de la température sur la résistance des joints brasés entre les bornes et les plages d'accueil sur un substrat.

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.

International Standard IEC 62137-1-2 has been prepared by IEC technical committee 91:

Electronics assembly technology.
The text of this standard is based on the following documents:
FDIS Report on voting
91/683/FDIS 91/699/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all the parts in the IEC 62137 series, under the general title Surface mounting

technology – Environmental and endurance test methods for surface mount solder joint, can

be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until

the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in

the data related to the specific publication. At this date, the publication will be

• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

ENVIRONMENTAL AND ENDURANCE TEST METHODS
FOR SURFACE MOUNT SOLDER JOINT –
Part 1-2: Shear strength test
1 Scope

The test method described in this part of IEC 62137 is applicable to leadless surface

mounting components and surface mounting connectors to which pull test is not applicable. It

is not applicable to multi-lead components and gull-wing leads.

The method is designed to test and evaluate the endurance of the solder joint between

component terminals and lands on a substrate, by means of a shear type mechanical stress.

This test is applicable to evaluate the effects of repeated temperature change on the strength

of the solder joints between terminals and lands on a substrate.
