Environmental testing - Part 2-69: Tests - Test Te/Tc: Solderability testing of electronic components and printed boards by the wetting balance (force measurement) method

Environmental testing - Part 2-69: Tests - Test Te/Tc: Solderability testing of electronic components and printed boards by the wetting balance (force measurement) method

IEC 60068-2-69:2017 outlines test Te/Tc, the solder bath wetting balance method and the solder globule wetting balance method to determine, quantitatively, the solderability of the terminations. Data obtained by these methods are not intended to be used as absolute quantitative data for pass–fail purposes. The procedures describe the solder bath wetting balance method and the solder globule wetting balance method. They are applicable to components and printed boards with metallic terminations and metallized solder pads. This document provides the measurement procedures for solder alloys both with and without lead (Pb). This edition includes the following significant technical changes with respect to the previous edition: - integration of IEC 60068-2-54; - inclusion of tests of printed boards; - inclusion of new component types, and updating test parameters for the whole component list; - inclusion of a new gauge R & R test protocol to ensure that the respective wetting balance equipment is correctly calibrated.

Essais d'environnement - Partie 2-69: Essais - Essai Te/Tc: Essai de brasabilité des composants électroniques et cartes imprimées par la méthode de la balance de mouillage (mesure de la force)

L'IEC 60068-2-69:2017 spécifie l'essai Te/Tc, la méthode de la balance de mouillage au bain de brasure et la méthode de la balance de mouillage à la goutte de brasure, pour déterminer quantitativement la brasabilité des sorties. Ces méthodes ne servent pas à fournir des données quantitatives absolues utilisées dans le cadre d'acception ou de rejet. Les modes opératoires décrivent la méthode de la balance de mouillage au bain de brasure ainsi que la méthode de la balance de mouillage à la goutte de brasure. Ces deux méthodes sont applicables aux composants et aux cartes imprimées munis de sorties métalliques et de plots de brasage métallisés. Le présent document fournit les modes opératoires de mesure pour les alliages de brasage avec et sans plomb (Pb). Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - intégration de l'IEC 60068-2-54; - introduction d'essais de cartes imprimées; - intégration de nouveaux types de composants et actualisation des paramètres d'essai pour la liste complète des composants; - introduction d'un nouveau protocole d'essai R&R de jauge pour assurer que la balance de mouillage est correctement étalonnée.

Environmental testing - Part 2-21: Tests - Test U: Robustness of terminations and integral mounting devices
SIST EN IEC 60068-2-21:2021

IEC 60068-2-21:2021 is applicable to all electrical and electronic components whose terminations or integral mounting devices are liable to be submitted to stresses during normal assembly or handling operations and is also applicable to surface mount devices (SMDs). This seventh edition cancels and replaces the sixth edition, published in 2006, and IEC 60068‑2‑77:1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
integration of parts of IEC 60068-2-77 (see Annex X); IEC 60068-2-77 is withdrawn with the publication of this document;
Annex X is added to show the correlation of the clauses and subclauses in this edition of IEC 60068-2-21 with the clauses in IEC 60068-2-21:2006 and IEC 60068-2-77:1999.

Environmental testing - Part 2-82: Tests - Test Xw1: Whisker test methods for components and parts used in electronic assemblies
SIST EN IEC 60068-2-82:2019

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.

Environmental testing - Part 2-58: Tests - Test Td: Test methods for solderability, resistance to dissolution of metallization and to soldering heat of surface mounting devices (SMD)
SIST EN 60068-2-58:2015

IEC 60068-2-58:2015 outlines test Td, applicable to surface mounting devices (SMD). This standard provides procedures for determining the solderability and resistance to soldering heat of devices in applications using solder alloys, which are eutectic or near eutectic tin lead (Pb), or lead-free alloys. The procedures use either a solder bath or reflow method and are applicable only to specimens or products designed to withstand short term immersion in molten solder or limited exposure to reflow systems. The solder bath method is applicable to SMDs designed for flow soldering and SMDs designed for reflow soldering when the solder bath (dipping) method is appropriate. The reflow method is applicable to the SMD designed for reflow soldering, to determine the suitability of SMDs for reflow soldering and when the solder bath (dipping) method is not appropriate. This edition includes the following significant technical changes with respect to the previous edition: - the addition of Sn-Bi low temperature solder alloy; - the addition of several reflow test conditions in Table 7 - Resistance to soldering heat - Test conditions and severity, reflow method; - introduction of reflow test method for Test Td3: Dewetting and resistance to dissolution of metallization; - implementation of guidance for the choice of a test severity in Clause B.3.

SIST EN 60068-2-83:2012

IEC 60068-2-83:2011 provides methods for comparative investigation of the wettability of the metallic terminations or metallized terminations of SMDs with solder pastes. Data obtained by these methods are not intended to be used as absolute quantitative data for pass - fail purposes. NOTE: Different solderability test methods for SMD are described in IEC 60068-2-58 and IEC 60068-2-69. IEC 60068-2-58 prescribes visual evaluation using solder bath and reflow method, IEC 60068-2-69 prescribes wetting balance evaluation using solder bath and solder globule method.
