SIST EN 60749-42:2014

Semiconductor devices - Mechanical and climatic test methods - Part 42: Temperature humidity storage

This part of IEC 60749 provides a test method to evaluate the endurance of semiconductor
devices used in high temperature and high humidity environments.
This test method is used to evaluate the endurance against corrosion of the metallic
interconnection of chips of semiconductor devices contained in plastic moulded and other
types of packages. It is also used as a means of accelerating the leakage phenomena due to
the moisture penetration through the passivation film and as a pre-conditioning for various
kinds of tests.

Dispositifs à semiconducteurs - Méthodes d'essais mécaniques et climatiques - Partie 42: Stockage - Température et humidité

L'IEC 60749-42:2014 décrit une méthode d'essai pour évaluer l'endurance des dispositifs à semiconducteurs utilisés dans les environnements à température élevée et à forte humidité. Cette méthode d'essai est utilisée pour évaluer la résistance à la corrosion des interconnexions métalliques des puces des dispositifs à semiconducteurs sous boîtiers moulés en plastique ou contenus dans d'autres types de boîtiers. Elle est aussi utilisée comme moyen pour accélérer le phénomène de fuite dû à la pénétration d'humidité à travers le film de passivation et comme préconditionnement en vue de différents types d'essais.

Polprevodniški elementi - Metode za mehansko in klimatsko preskušanje - 42. del: Shranjevanje pri določeni temperaturi in vlažnosti (IEC 60749-42:2014)

Ta del standarda IEC 60749 podaja preskusno metodo za ocenjevanje vzdržljivosti polprevodniških elementov, uporabljenih v okoljih z visoko temperaturo in visoko vlažnostjo. Ta preskusna metoda se uporablja za ocenjevanje vzdržljivosti proti koroziji kovinskih medsebojnih povezav čipov polprevodniških elementov na plastičnih modulih in drugih vrstah embalaže. Uporablja se tudi kot sredstvo za pospeševanje fenomena puščanja zaradi prodiranja vlage skozi pasivirano plast in kot predpriprava za različne preskuse.

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,
