标准摘要
[中文适用范围]： 本部分IEC 60749提供了一种评估塑料封装表面安装器件(SMDs)半导体耐焊接热性能的方法。该测试是破坏性的。 [外文原描述]： IEC 60749-20:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60749-20:2020 provides a means of assessing the resistance to soldering heat of semiconductors packaged as plastic encapsulated surface mount devices (SMDs). This test is destructive. This edition includes the following significant technical changes with respect to the previous edition: - incorporation of a technical corrigendum to IEC 60749-20:2008 (second edition ); - inclusion of new Clause 3; - inclusion of explanatory notes.
