Solder fatigue is the mechanical degradation of solder due to deformation under cyclic loading. This can often occur at stress levels below the yield stress of solder as a result of repeated temperature fluctuations, mechanical vibrations, or mechanical loads. Techniques to evaluate solder fatigue behavior … See more Solder is a metal alloy used to form electrical, thermal, and mechanical interconnections between the component and printed circuit board (PCB) substrate in an electronic assembly. Although other forms of cyclic … See more While not as prevalent as thermomechanical solder fatigue, vibration fatigue and cyclic mechanical fatigue are also known to cause solder failures. Vibration fatigue is … See more • • See more • Solder joint fatigue calculators See more During a product's operational lifetime it undergoes temperature fluctuations from application specific temperature excursions and self-heating due to component See more Solder damage models take a physics-of-failure based approach by relating a physical parameter that is a critical measure of the … See more • Cold solder joint • Creep (deformation) • Fatigue (material) • Plasticity (physics) See more
