In this case, the screening speed and efficiency will also increase. But too large vibration frequency will reduce the service life of vibrating screen. For raw materials with large sizes, we should adopt large amplitude and low vibration frequency. For raw materials with small sizes, we should adopt small amplitude and high vibration frequency.

Here, the stress applied is high temperature, and the screen is typically called 'burn-in'. Other types of latent failure modes are accelerated by other stresses. Vibration is effective for failure modes that are due to poor solder joint quality. Dwells at hot and cold temperatures are effective for exposing solder joints prone to solder creep.
