Méthodes d’essai pour les matériaux électriques, les cartes imprimées et autres structures d’interconnexion et ensembles - Partie 5-503 : Méthodes d’essai générales pour les matériaux et les assemblages - Essais des filaments anodiques conducteurs (CAF) des cartes à circuit imprimé

L’IEC 61189-5-503:2017 spécifie le filament anodique conducteur (ci-après appelé CAF) et spécifie non seulement l’essai continu de température et d’humidité, mais aussi un essai cyclique de température-humidité et un essai de vapeur pressurisée non saturée (HAST).

Preskusne metode za električne materiale, tiskane plošče ter druge povezovalne strukture in sestave - 5-503. del: Splošne preskusne metode za materiale in sestave - Preskušanje tiskanih vezij s prevodnimi anodnimi vlakni (CAF)

Ta del standarda IEC 61189 opredeljuje prevodno anodno vlakno (v nadaljevanju CAF) ter navaja preskus s stalno temperaturo in vlago, ciklični preskus s temperaturo in vlago in preskus z nenasičeno paro pod pritiskom (HAST).
