Purpose

This study aims to present a more accurate lifetime prediction model considering solder chemical composition.

Design/methodology/approach

Thermal cycling and standard creep tests as well as finite element simulation were used.

Findings

The study found lower error in the solder joint lifetime evaluation. The higher the Ag content is, the higher the lifetime is achieved.

Originality/value

It is confirmed.
