| Popis: | 97 Experienced by the end of 2008's financial storm, the personal consumption concept has been changed, people pay more attention for quality requirements of electronic products, and it is one of the major considerations for the life assurance of consumer’s products. The object of this research is how to evaluate the MTTF of wireless mouse products and how to proceed with reliability tests. We apply the different stresses (example for temperature, humidity, random vibration, ESD, ..., and so on) to execute reliability testing, and we find the suitable relationship between the MTTF and stress. And we adopt suitable life-stress relationship to proceed the accelerated life testing. We collect and analysis failure data in a short period to find the suitable life distribution and mouse’s MTTF at normal stress level. The extrapolated MTTF at normal operating condition of 25℃, 65%RH, 5.6KV and 8 hours mission time per day is 32848.661 hours (approximate 11.24 years). Normally the company that manufactures mouse spends 20~30 days for the MTTF testing. Our research’s results obtain the MTTF of wireless mouse at a short period (2 days), and the results are good references for the industries to perform acceleration life testing and estimate MTTF in the future. |
