EVS-EN IEC 60749-30:2020

IEC 60749-30:2020 establishes a standard procedure for determining the preconditioning of non-hermetic surface mount devices (SMDs) prior to reliability testing. The test method defines the preconditioning flow for non-hermetic solid-state SMDs representative of a typical industry multiple solder reflow operation. These SMDs are subjected to the appropriate preconditioning sequence described in this document prior to being submitted to specific in-house reliability testing (qualification and/or reliability monitoring) in order to evaluate long term reliability (impacted by soldering stress). This edition includes the following significant technical changes with respect to the previous edition: - inclusion of new Clause 3; - expansion of 6.7 on solder reflow; - inclusion of explanatory notes and clarifications.
