Semiconductor devices - Mechanical and climatic test methods - Part 7: Internal moisture content measurement and the analysis of other residual gases

This International Standard specifies the testing and measurement of water vapour and other
gas content of the atmosphere inside a metal or ceramic hermetically sealed device. The test
is used as a measure of the quality of the sealing process and to provide information about
the long-term chemical stability of the atmosphere inside the package. It is applicable to
semiconductor devices sealed in such a manner but generally only used for high reliability
applications such as military or aerospace. This test is destructive.

Dispositifs à semiconducteurs - Méthodes d'essais mécaniques et climatiques - Partie 7: Mesure de la teneur en humidité interne et analyse des autres gaz résiduels

La CEI 60749-7:2011 spécifie les essais et les mesures de la teneur en vapeur d'eau et en autres gaz de l'atmosphère à l'intérieur d'un dispositif métallique ou céramique scellé hermétiquement. L'essai est utilisé en tant que mesure de la qualité du procédé de scellement et en vue de fournir des informations sur la stabilité chimique à long terme de l'atmosphère à l'intérieur du boîtier. Il est applicable à tous les dispositifs à semiconducteurs scellés de cette manière mais généralement réservés pour les applications à haute fiabilité comme dans les domaines militaire et spatial. Le présent essai est destructif. Cette deuxième édition annule et remplace la première édition parue en 2002, dont elle constitue une révision technique. Cette seconde édition a été complètement remaniée de manière à l'aligner sur le texte des dernières versions de la MIL-STD-750, méthode 1018 et la MIL-STD-883, méthode 1018. La modification principale est la suppression des deux méthodes alternatives, anciennement désignées méthode 2 et méthode 3.

Polprevodniški elementi - Metode za mehansko in klimatsko preskušanje - 7. del: Merjenje količine notranje vlage in analiza drugih preostalih plinov

Ta mednarodni standard določa preskušanje in merjenje količine vodne pare in drugih plinov v atmosferi znotraj kovinskih ali keramičnih hermetično zaprtih elementov. Preskus se uporablja za merjenje kakovosti procesa zatesnitve in za zagotavljanje informacij o dolgoročni kemijski stabilnosti atmosfere v paketu. Velja za tako zatesnjene polprevodniške elemente, vendar se v splošnem uporablja samo za aplikacije, kjer je potrebna velika zanesljivost, na primer v vojski ali aeronavtiki. Ta preskus je porušitven.

Part 7: Internal moisture content measurement

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.
International Standard IEC 60749-7 has been prepared by IEC technical committee 47:
Semiconductor devices.
This second edition cancels and replaces the first edition published in 2002 and constitutes a
technical revision. This second edition has been completely re-written so as to align it with the
text of the latest versions of MIL-STD-750, method 1018 and MIL-STD-883, method 1018.
The main change is the removal of the two alternative methods formerly designated method 2
and method 3.
