| Abstract: | Spacecraft electronic equipments often suffer all kinds of vibration environments. The lead and solder may be fatigue in the rough stochastic vibration. The paper presents a practical and effective method to analyze the fatigue of lead and solder in the stochastic vibration on the basis of Miner＇s Cumulative Damage and Three Band Technique. |
