Since the resonant frequency of 480 Hz for random vibration is higher than 301 Hz, the 480 Hz dominates and will satisfy both the shock and vibration requirements (the higher the resonant frequency, the lower the PCB displacement and the lower the stress). Step 5. Determine the resonant frequency of the PCB assembly when mounted in the chassis.
