1. The storage environment of the terminals is different, from a clean, heated or air-conditioned, wet warehouse, office or factory to an uncontrollable environment.
In the case of heat, humidity or corrosion, the service life of the terminal will be seriously affected.
2. The transportation environment factors in the terminal involve problems caused by vibrations and collisions caused by transportation vehicles and other mechanical devices, road surfaces, and loading and unloading tools during operation.
Extreme temperatures often combine and exacerbate the effects of vibration and collision.
3. The reliability of the terminals is a very important consideration in business decisions.
From the point of view of a quality engineer or a reliability engineer, reliability should be defined as "continuous performance or likelihood of zero-failure operation under established conditions," or "something under specified conditions, at specific intervals." The possibility of functioning properly in its function.
