Environmental testing - Part 2-82: Tests - Test Xw1: Whisker test methods for components and parts used in electronic assemblies

IEC 60068-2-82:2019 specifies tests for the whiskering propensity of surface finishes of electric or electronic components and mechanical parts such as punched/stamped parts (for example, jumpers, electrostatic discharge protection shields, mechanical fixations, press‑fit pins and other mechanical parts used in electronic assemblies) representing the finished stage, with tin or tin-alloy finish. Changes of the physical dimensions of mould compounds, plastics and the like during the required test flow are not considered or assessed. The test methods have been developed by using a knowledge-based approach. This edition includes the following significant technical changes with respect to the previous edition: – extension of the scope of the test standard from electronic to electromechanic components and press-fit pins, which are used for assembly and interconnect technology; – significant reduction of the testing effort by a knowledge-based selection of test conditions i.e. tests not relevant for a given materials system can be omitted (see Annex D); – harmonization with JESD 201A by omission of severities M, N for temperature cycling tests; – highly reduced test duration (1 000 h instead of 4 000 h) for damp-heat test by introducing test condition at elevated humidity of 85 % R.H. and a temperature of 85 °C providing increased severity.

Essais d’environnement - Partie 2-82: Essais - Essai Xw1: Méthodes de vérification des trichites pour les composants et les pièces utilisés dans les ensembles électroniques

L'IEC 60068-2-82:2019 spécifie des essais de vérification de la propension au développement des trichites pour les finis de surface des composants électriques ou électroniques et des pièces mécaniques comme les pièces embouties/estampées (par exemple cavaliers, écrans de protection contre les décharges électrostatiques, fixations mécaniques, contacts insérés à force et autres pièces mécaniques utilisées dans les ensembles électroniques) qui représentent la phase de finition, avec un fini en étain ou en alliage d'étain. Les modifications des dimensions physiques des composants moulés, des plastiques et autres pendant le flux d'essai exigé ne sont pas prises en compte ni évaluées. Les méthodes d'essai ont été mises au point en utilisant une approche fondée sur la connaissance. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: – extension du domaine d'application de la norme d'essai des composants électroniques aux composants électromécaniques et aux contacts insérés à force qui sont utilisés pour la technologie d'assemblage et d'interconnexion; – réduction significative de l'effort d'essai par une sélection de conditions d'essai fondée sur la connaissance, c'est-à-dire que les essais non applicables à un système de matériaux donné peuvent être omis (voir Annexe D); – harmonisation avec la JESD 201A par omission des sévérités M et N pour les essais de cycle thermique; – réduction considérable de la durée d'essai (1 000 h au lieu de 4 000 h) pour l'essai de chaleur humide par l'introduction d'une condition d'essai à humidité élevée de 85 % H.R. et d'une température de 85 °C assurant une plus grande sévérité.

Okoljsko preskušanje - 2-82. del: Preskusi - Preskus Xw1: Preskusna metoda za nitke v komponentah pri elektronskih sestavih

Ta del standarda IEC 60068 določa preskuse nagnjenosti k tvorjenju vlaknastih kristalov, ki se lahko pojavijo na prevlekah električnih ali elektronskih komponent in mehanskih delov, kot so vgravirani/vtisnjeni deli (na primer povezovalni vodi, zaščite pred elektrostatičnimi razelektritvami, mehanske pritrditve, zatič za pritrditev s pritiskom ter drugi mehanski deli, ki se uporabljajo v elektronskih sklopih) in predstavljajo zaključno fazo, s prevleko iz kositra ali kositrove zlitine. Spremembe fizičnih mer kalupnih mas, polimerov in podobnega med zahtevanim preskušanjem niso obravnavane ali ocenjene. Preskusne metode so bile razvite z na znanju temelječim pristopom.
Ta dokument lahko uporabljajo tudi poddobavitelji, na primer delavnice za prevleke, delavnice za vtiskavanje ali drugi ponudniki storitev za zagotavljanje enakomerne kakovosti površine v oskrbovalni verigi.
Te preskusne metode se uporabljajo z opredeljenimi kriteriji sprejemljivosti, če jih predpisuje ustrezna specifikacija komponente ali uporabe.
Preskusi, ki so opisani v tem dokumentu, se uporabljajo za temeljno kvalifikacijo, redno spremljanje skladno s točko 7 in za spremembe v tehnologiji ali proizvodnih postopkih obstoječih površin skladno s točko 9.
Ta preskusna metoda ne zajema priključnega dela konektorjev. Za priključne dele konektorjev se uporablja IEC 60512-16-21.
