J-STD-004标准与助焊剂的选用

J-STD-004 Standard and Selection & Use of Soldering Flux

简要介绍了美国联合工业标准Ｊ－ＳＴＤ－００４对助焊剂的分类方法与有关技术要求，并就该标准与传统各类助焊剂标准的异同进行了分析比较。同时，根据作者多年从事电子产品失效分析与助焊剂产品检测的经验，提出了各种不同产品或工艺线对助焊剂产品的选用方法和基本原则。

The classified methods and requirements of American national joint industry standard J-STD-004 were introduced in this article simply, and a comparison between J-STD-004 and other flux standard has been taken too. Meanwhile, basic means and principles of Choosing and using fluxes have been presented on the basis of author＇s experience in many years from testing fluxes and failure analysis of electronic products in the end.
