Reflow Soldering 101

Reflow Soldering 101

Reflow soldering, the most common method of attaching surface mount components to a circuit board, plays a critical role in the overall electronics assembly process. Successful reflow soldering depends on knowledge of the reflow process setup, requirements for fixturing and tooling, baseline process parameters and their influence on solder joint quality, and troubleshooting common process defects.

Professor Martin Anselm, Ph.D. from Rochester Institute of Technology will guide you through this informative online course providing a basic understanding of the reflow soldering process.
