Constant stress ADT for superluminescent diode and statistical analysis
Within severe time and cost constraints, constant stress accelerated degradation testing (CSADT) was utilized to evaluate high reliability and long life of Superluminescent Diode (SLD). Firstly, the assumptions of CSADT were given On the basis of FMECA and FTA results of SLD, accelerated model was determined. Then, by the means of drift Brownian movement crossing continuous boundary and time scale transformation, reliability evaluation model of CSADT with non-linear degradation was generated. According to the independence increment property of drift Brownian movement, the maximum likelihood and regression analysis were used to evaluate the parameters of reliability model. Engineering application validated that reasonable evaluated results could be obtained by the methodology proposed in this paper.
