Industrial applications that are designed for vehicles or outdoor applications make special demands. Extreme environmental conditions – operation in high or low temperatures or thermal shock, high humidity or electromagnetic disturbances and startups in low temperature – account for most of these demands. Since system failures often result in high costs, the system must be very reliable under every possible operating condition, and it must provide the highest level of failure tolerance. Extended Temperature Testing ensures the system's reliability before under extreme operating environments.

Phoebus Design involves designing an SBC with pre-qualified onboard components to operate without failure in extreme temperatures. It is also mandatory that each board undergoes a 5-day testing for operation under extreme temperatures.

Advantech's Phoebus testing process guarantees that the boards can operate continuously under extreme temperatures (-40 and 85 ℃ ) for at least 8 hours throughout the whole operation time.
