Semiconductor devices - Mechanical and climatic test methods - Part 37: Board level drop test method using an accelerometer

IEC 60749-37:2022 is available as IEC 60749-37:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60749-37:2022 provides a test method that is intended to evaluate and compare drop performance of surface mount electronic components for handheld electronic product applications in an accelerated test environment, where excessive flexure of a circuit board causes product failure. The purpose is to standardize the test board and test methodology to provide a reproducible assessment of the drop test performance of surface-mounted components while producing the same failure modes normally observed during product level test. This edition includes the following significant technical changes with respect to the previous edition: - correction of a previous technical error concerning test conditions; - updates to reflect improvements in technology.

IEC 60749-37:2022 est disponible sous forme de IEC 60749-37:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 60749-37:2022 fournit une méthode d’essai destinée à évaluer et comparer la performance de chute des composants électroniques à montage en surface dans des applications de produits électroniques portatifs dans un environnement d’essai accéléré, où une flexion excessive d’une carte de circuit imprimé provoque une défaillance de produit. Le but est de normaliser la carte d'essai et la méthodologie d'essai pour fournir une évaluation reproductible de la performance d'essai de chute des composants à montage en surface, en reproduisant les mêmes modes de défaillances que ceux observés normalement au cours d'un essai au niveau du produit. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - correction d’une erreur technique précédente concernant les conditions d’essai; - mises à jour afin de refléter les progrès technologiques.

Polprevodniški elementi - Mehanske in klimatske preskusne metode - 37. del: Metoda preskušanja s padcem z namizne višine z uporabo pospeševalnika (IEC 60749-37:2022)

Ta del standarda IEC 60749 podaja preskusno metodo, ki je namenjena ocenjevanju in primerjavi učinka padca površinsko nameščenih elektronskih komponent za uporabo v ročnih elektronskih izdelkih v pospešenem preskusnem okolju, v katerem upogibanje plošče s tiskanim vezjem povzroči okvaro izdelka. Namen je standardizirati preskusno ploščo in preskusno metodologijo, da se zagotovi ponovljiva ocena uspešnosti preskusa padca površinsko nameščenih komponent, ter obenem ustvariti enake vrste okvar, kot so običajno opažene med preskusom na ravni izdelka.
Namen tega dokumenta je predpisati standardizirano preskusno metodo in postopek poročanja. Ta dokument ni preskus ustreznosti komponent in naj ne bi nadomeščal katerega koli preskusa na ravni sistema, ki se včasih uporablja za preverjanje ustreznosti določenega ročnega električnega izdelka. Standard naj ne bi zajemal preskusa padca, ki je potreben za simulacijo udarcev elektronskih komponent ali sestavov tiskanih vezij, povezanih z odpremo in rokovanjem. Te zahteve so že obravnavane v preskusnih metodah, kot je standard IEC 60749-10. Metoda se uporablja tako za površinsko nameščene komponente z okrovi z matričnimi priključki v ravnini kot površinsko nameščene komponente s svinčenim obodom.
Ta preskusna metoda uporablja pospeševalnik za merjenje trajanja mehanskega udarca in uporabljene stopnje, ki je sorazmerna z obremenitvijo dane komponente, nameščene na standardno ploščo. Preskusna metoda, opisana v standardu IEC 60749-40 uporablja merilnik deformacije za merjenje deformacije stopnje deformacije plošče v bližini komponente. Specifikacija stranke določa, katera preskusna metoda mora biti uporabljena.

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.
