Addressing Low-Temperature Rework Concerns

This research article explores the implementation of low-temperature solders, focusing on bismuth-containing alloys and their rework challenges. It assesses the performance of eutectic tin/bismuth solid wire and SAC305 flux cored wire in rework settings, providing insights into material properties, solder joint quality, and operator training. The study aims to guide manufacturers in effectively using low-temperature solders while identifying potential issues in the rework process.
