The physical separation signal failed to display during a missile＇s free flight vibration test,the cause of which is determined as the malfunction of CAK type tantalum capacitor on the electric connec- tion board via fault tree anarysis and eliminating all invalid causes.Failure analysis is conducted on the capacitor and corrective measure pointing to the failure is advanced in this paperMore severe requirement on component screening process can effectively avoid the occurrence of similar fault.
