LIFE EXPERIMENT REPORTThis report is adapted to similar manufacturing process and similarprojects as the right examples.A001Representative Test P/N:A001Equipment:OVEN►Test PlanL10 Expectancy:52,560hours minimun@ the temperature of 80°C According to the equation for Weibull distribution, MTTF ≒ 7 x L10 = the total test time (t) for verifying the above life estimation by the equations, t = 1.036 x MTTF x {(Br;c)÷n}0.91÷AF, and AF = 2(Ts-Tu)/10367,920hours And we rely on a zero failure weibull test strategy and accelerated testing technique, to determine where, (Br;c) is poisson distribution factor with the failure number of r equal to 0 and the decimal confindence level of c equal to 0.90(90%)►Test procedure (1). Check the flatness , performance (2). Put the product to the oven (3). Power on►Fail Definition (4). Start the test (5). Finish the test and power off the oven (6). Test the performance and flatness (3). Loading test (60PSI) couldn't over SPEC. 10%. (4). Performance test couldn't over SPEC. 10°%PoissonDistributionFactorBr;cRequlred testtime with 1failuret (hours) (1). No fail due leak (2).
