Scope

This document specifies the determination method for trace impurity elements in high-silicon aluminum alloys (with a silicon content of ≥40%) used in electronic packaging. This document is applicable to the determination of trace impurity elements in high-silicon aluminum alloys (with a silicon content of ≥40%) used in electronic packaging. The determination scope covers all impurity elements except gaseous elements, with a mass fraction of 0.1 to 500, and after being corrected by standard samples, accurate quantitative analysis of the samples can be carried out. 1.
