Which Parameter Matters Most? A Structured Literature Review and Unified Simulation Comparison of Design and Material Influences on PCBA Solder-Joint Lifetime
This paper presents a condition-controlled, simulation-based ranking of five key design and material parameters governing solder-joint fatigue life in printed circuit board assemblies (PCBAs) under thermal cycling: substrate material, substrate thickness, copper thickness, solder alloy, and solder thickness. All parame...
