TL;DR: The improved time-variant reliability model proposed can avoid the redundant and complex calculations and obtain accurate reliability results, and is proved to be exceptionally effective for engineering applications.

TL;DR: In this article, the authors proposed a lifetime prediction method for solid state lighting power converter based on SPICE models and finite element thermal simulations, where the estimated lifetime can be obtained by a number of iterations of electronic and thermal performances of the interested power converter.

TL;DR: Results show that the solder joints are one of the key weakness points that influence the reliability of MEMS package and the maximum effective stress in the structure occurs at the outer corner in the outermost solder point.

TL;DR: In this article, a method of modeling the degradation of GaAs space solar cells is proposed to find one crucial performance parameter to depict the degradation process, and reliability can be calculated through the attenuation of output power which was easy to detect and record.

TL;DR: In this paper, the effects of irradiation hardening and irradiation embrittlement on fatigue performance parameters were quantified and a fatigue life prediction model was developed based on this model, which takes into account the cumulative effect of a neutron dose, the total fatigue damage was calculated according to Miner's linear cumulative damage law, and the reliability analysis was carried out using the Monte Carlo simulation method.
