| Abstract: |
| Objective To evaluate the residual storage life of typical electronic equipment under integrated environmental stresses through accelerated test. Methods In allusion to the integration of various environmental stresses that affects storage life of electric equipment, an accelerated test method considering the integrated stress of temperature-vibration-electric was proposed. Meanwhile, an accelerated life test under the proposed method was conducted with typical electric equipment which has already reached the design storage life as experiment subject. Results Through an accelerated storage test under integrated stresses of about 4 months, the typical electronic equipment's residual storage life of 5 years was verified and evaluated, and good experimental results were obtained. Conclusion The accelerated test under integrated stresses takes into full consideration of the environmental factors experienced by electric equipment during the storage process, and it can accurately simulate the cumulative effects of various environmental stresses during the service period and different mission stages. |
