Hi Lonnie, It seems SKB ask us to provide the calcultion B0.01~B10 based on the Eagle original MTBF report? Anyway, I have sent this request to our HWQA team for evaluation. I will get back to you tomorrow once I get the reply from our QA team tomorrow. Thanks, Regards, Sean |

Hi Lonnie, According to our QA, we have to collect the samples q'ty/ test time/ the failure rate & time of the burn-in test in Eagle's production, so that we have data to calculate the MTBF B10 However, our factory PE told us that they don't found any defect boards in burn-in station from 04/2020 to now. So, the B10 seems can not be calculated. Anyway, we are checking with factory side to know the exact number of samples, which has been tested in the burn-in since 04/2020. Could you check it and let us know your idea? Thanks, Regards, Sean |
