Novel Solder Alloy: Wide Service Temperature Capability for Automotive Applications (original) (raw)

With the growing demand for high reliability in automotive electronics, particularly in electric vehicles and self-driving cars, this research introduces a novel solder alloy, Indalloy 276, specifically designed for superior performance under both moderate and high service temperature conditions. The study characterizes its physical and mechanical properties, compares it with existing solder alloys like SAC305 and SACBSbN, and evaluates its reliability through various thermal and mechanical tests, demonstrating its advantage in thermal cycling and aging contexts. The results indicate that Indalloy 276 outperforms conventional solders, suggesting its potential for enhancing reliability in automotive applications.
